Revelation 16

1 Then I heard a loud voice from the temple telling the seven angels, “Go and pour out on the earth the seven bowls of the wrath of God.”

2 So the first angel went and poured his bowl on the earth, and a foul and painful sore came on those who had the mark of the beast and who worshiped its image.

3 The second angel poured his bowl into the sea, and it became like the blood of a corpse, and every living thing in the sea died.

4 The third angel poured his bowl into the rivers and the springs of water, and they became blood. 5 And I heard the angel of the waters say,

“You are just, O Holy One, who are and were, for you have judged these things;
6 because they shed the blood of saints and prophets, you have given them blood to drink.
It is what they deserve!”

 7 And I heard the altar respond, “Yes, O Lord God, the Almighty, your judgments are true and just!”

8 The fourth angel poured his bowl on the sun, and it was allowed to scorch them with fire; 9 they were scorched by the fierce heat, but they cursed the name of God, who had authority over these plagues, and they did not repent and give him glory.

10 The fifth angel poured his bowl on the throne of the beast, and its kingdom was plunged into darkness; people gnawed their tongues in agony, 11 and cursed the God of heaven because of their pains and sores, and they did not repent of their deeds.

12 The sixth angel poured his bowl on the great river Euphrates, and its water was dried up in order to prepare the way for the kings from the east. 13 And I saw three foul spirits like frogs coming from the mouth of the dragon, from the mouth of the beast, and from the mouth of the false prophet. 14 These are demonic spirits, performing signs, who go abroad to the kings of the whole world, to assemble them for battle on the great day of God the Almighty. 15 (“See, I am coming like a thief! Blessed is the one who stays awake and is clothed, not going about naked and exposed to shame.”) 16 And they assembled them at the place that in Hebrew is called Harmagedon.

17 The seventh angel poured his bowl into the air, and a loud voice came out of the temple, from the throne, saying, “It is done!” 18 And there came flashes of lightning, rumblings, peals of thunder, and a violent earthquake, such as had not occurred since people were upon the earth, so violent was that earthquake. 19 The great city was split into three parts, and the cities of the nations fell. God remembered great Babylon and gave her the wine-cup of the fury of his wrath. 20 And every island fled away, and no mountains were to be found; 21 and huge hailstones, each weighing about a hundred pounds, dropped from heaven on people, until they cursed God for the plague of the hail, so fearful was that plague.

The final cycle of judgments begins with the seven bowls held by the seven angels. There are many similarities in this scene with the seven seals in Revelation 6-8:4 and the seven trumpets in Revelation 8:5-11:13 which I explore in greater depth in the exploration of Revelation 6, but with this cycle there are several parallels with the signs and wonders, or plagues as they are commonly known, from Exodus 7-12. The Exodus is the defining narrative of the Hebrew people and one thing we have seen from Revelation is John’s deep familiarity with the Hebrew scriptures. As I mentioned when I wrote about the plagues in Exodus and as I have mentioned throughout this exploration of Revelation one of the often-unnoticed portions of these passages is the divine restraint that is exercised. Throughout Revelation there has been a desire for repentance, for those who have allied themselves with the forces opposed to God and creation to change their allegiance. Revelation operates under the prophetic hope that every knee will bow, and every tongue confess that God is the Lord and master of the earth. But here, echoing the language of Jesus with Nicodemus in the gospel of John we will find that ‘this is the judgment, that the light has come into the world, and people loved darkness rather than the light because their deeds were evil.” (John 3: 19)

The pouring of libations as an offering to a god was practiced by cultures throughout the Greco-Roman world including in Jewish worship at the temple, but here we see the practice inverted: instead of the faithful devotees of a deity pouring out wine or blood to appease a deity now it is the God of Israel who has the angels of God pour out the wine of God’s wrath upon God’s adversaries on earth. In chapter fourteen God trod the winepress of the harvested grapes and what came forth was blood, now we will see the harvest of the earth returned to the earth. The angel of the sea will proclaim that God is just for what God is doing, and those in the altar can also celebrate the long-awaited justice as the final bowls are poured and God’s judgment is finally ended.

The first bowl causes those who have the mark of the beast to have a painful sore. Much like the boils of Exodus 9: 8-12, the plague is painful but not fatal and still allows people a time to change their allegiance. There is time for repentance and in both Jewish and Greco-Roman cultures the expectation would be that plagues like the ones throughout this chapter would be divine judgment and the proper response would be to seek out how to reconcile oneself with the offended deity.  As Craig Koester can state about this first bowl:

Yet there is a divine restraint. Those who received the beast’s mark seemed to escape the threat of death under the beast, while those who refused the mark were to be killed (13:15). God’s plague is not a simple reversal of this practice. Painful though it is, the sore that God inflicts on the followers of the beast is less severe than the death that the beast inflicts upon the followers of the Lamb. (Koester, 2014, p. 654)

The second and third bowls cause the waters of the earth (first the sea and then the streams and springs) to become blood. There is a sense of justice that those who have poured out the blood of the saints and martyrs are now forced to drink blood from their own wells. Their own actions which forced the creation to drink up the blood of the fallen now sees the creation returning to the people the drink which the soil has drunk on the field of war or from sites of execution and coliseums throughout the empire. The Hebrew people often associated angels with being associated with elements like fire, water, thunder and here the angel of the water proclaims the justice of the command of God to cause bloody waves to come upon the shore and bloody rivers and springs to provide an additional sign of God’s judgment. Yet, even here there is not death. Much like the transformation of the Nile River to blood (Exodus 7: 14-25) there is a chance for life to continue and for repentance to occur. Yet, God has heard the suffering of God’s people and God is now judging those who have oppressed the people and the creation.

The fourth angel’s bowl being poured upon the sun does not have a parallel among the signs and wonders in Egypt, but it continues the use of the creation as an instrument of God’s judgment. Yet, even this fiery wrath does not bring about repentance, in fact it brings about the opposite. Those who remain aligned with the beast and with Satan will not change their allegiance at this point so instead of pleading for God’s forgiveness or mercy they curse God. Similarly, the darkness which plunges the empire of the beast into darkness may cause people to gnaw their tongues in agony (a phrase with a similar meaning to gnashing of teeth) and for a second time to curse God. In the signs and wonders in Egypt darkness was the penultimate sign and it showed the powerlessness of the Egyptian gods (particularly Ra) to oppose the Lord, the God of Israel (Exodus 10: 21-29). Here the beast and the forces of the beast are also powerless in comparison to God’s might.

Like Egypt gathering its forces for a decisive elimination of the people of God after the signs and wonders in the Exodus, the first six bowls cause the forces opposed to God to assemble for a final conflict. The drying up of the Euphrates can allow the people of God to remember how God would allow the people of God to pass through the Red Sea under Moses (Exodus 14), the Jordan River under Joshua, (Joshua 3), or how Elijah and Elisha could pass through the Jordan in 2 Kings 2. Another level of memory may associate the Euphrates with the Assyrian and Babylonian empires who conquered Israel and Judah respectively, since both empires were based along the Euphrates. Finally, the Euphrates formed a barrier between the Roman empire and the Parthians empire to the east. The kings from the east may refer to the fear that the Parthian empire would someday invade Rome, or it may refer to a tradition that emperor Nero would return with a large force from the Parthians were some believed he had fled to, or it could refer to the idea of a great gathering of the kings of the earth for a final war to end all wars against each other and the forces of God.

The frog like demonic spirits which come from the mouth of the dragon, the beast and false prophet and speak with their words to deceive in opposition to God. On the one hand, the frog like spirits link this passage with the frogs of Exodus 8:1-15 but these take a much more active role in the movement towards the final conflict. In Revelation they are the response of the adversaries of God in response to the judgment being poured out upon the kingdom of the beast. They rally those loyal to the beast to remain unified in their opposition to the reign of God. To the early Christians the military might of the empire must have seemed to be an indomitable force and yet, amid the assembling of military might we are reminded that Christ is coming at a time when we do not expect. Christ breaks in like a thief in the night and these followers of Christ are to remain faithful even when they may appear to be powerless.

Armageddon, or Harmegedon, most likely links the Hebrew word for hill or mountain (har) with Megiddo. Megiddo is located on the Jezreel plain on the route linking Egypt with Syria and is a place of several conflicts in the scriptures including Deborah’s victory over Sisera and the Canaanites (Judges 5: 19) and it is the region where King Ahaziah (2 Kings 2: 27) and King Josiah of Judah (23:29) die in battle.  The connection with Revelation, particularly by the spelling and content, is most likely Zechariah 12: 11 where God intervenes to provide victory against an enemy who is threatening the people of Judah:

On that day the mourning in Jerusalem will be as great as the mourning for Hadad-rimmon in the plains of Meggido.

As Zechariah continues to move towards its climax the nations will gather against Jerusalem and as half of the city is cut off God finally intervenes and goes forth to fight against the nations. John frequently joins multiple passages together in Revelation’s imagery and here the mountains probably come from the invasion of the forces of Gog and Magog, which will be referenced in Revelation 19.

Regardless of geography or scriptural references the progression of the narrative is easy to follow: in response to the actions of God in judgment the forces opposed to God’s reign unite in a common location for a final stand. The dragon, who was already thrown out of heaven in Revelation 12, and his allies prepare for a final act of defiance against God’s will.

With the final bowl poured out and the declaration of the completion of the cycle the earth and skies react in judgment against the city and the forces opposed to God. The metaphorical telling of the judgment of Babylon (Rome) will continue in Revelation 17-18, but here in a hailstorm far more violent than the lethal thunder and hail of Exodus 9: 13-35 and an earthquake unlike any the world had recorded the power of God’s among the creation is unleashed and the great city along with the cities of the nations fell. The disasters in the vision would be rightly called ‘acts of God’ showing God’s judgment upon those who continue to hold to the dragon and the beasts in their allegiance. Yet, unlike Pharaoh who can declare after the hailstones, “This time I have sinned; the LORD is right, and I and my people are in the wrong.” (Exodus 9: 27), the people who have received the mark of the beast curse (literally blaspheme) God for a third time in the chapter. With the nations assembled for war the time of waiting is finally ended. Those who still resist the oncoming reign of God now have come to the end of God’s restraint. It is a time of great reversals, which reminds me of the language of the extended judgment of Babylon in Jeremiah 50-51, particularly:

Flee from the midst of Babylon, save your lives, each of you!
Do not perish because of her guilt, for this is the time of the LORD’s vengeance;
he is repaying her what is due.
Babylon was a golden cup in the LORD’s hand, making all the earth drunken;
the nations drank of her wine, and so the nations went mad. Jeremiah 51: 6-7

Now Babylon, the beast, the dragon and all the other forces opposed to God have gone mad and now they must drink the cup of God’s fury, the justice of the slain. In the following two chapters as Babylon falls and the princes and merchants mourn for her they will, in the language of Jeremiah 51: 8-9 find that there is no balm that can heal the fallen city. The cry for her judgment has reached the ears of God, the harvest of their actions has been turned into the bloody waters they drink, and their opposition to God is leading them to their destruction.

Revelation 15 A Song Before the Wrath

York Minster, Great East Window, 4a, The Plague Angels and the Harpers (1405-1408)

Revelation 15

1 Then I saw another portent in heaven, great and amazing: seven angels with seven plagues, which are the last, for with them the wrath of God is ended.

2 And I saw what appeared to be a sea of glass mixed with fire, and those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands. 3 And they sing the song of Moses, the servant of God, and the song of the Lamb:

“Great and amazing are your deeds, Lord God the Almighty!
 Just and true are your ways, King of the nations!
4 Lord, who will not fear and glorify your name? For you alone are holy.
All nations will come and worship before you, for your judgments have been revealed.”

5 After this I looked, and the temple of the tent of witness in heaven was opened, 6 and out of the temple came the seven angels with the seven plagues, robed in pure bright linen, with golden sashes across their chests. 7 Then one of the four living creatures gave the seven angels seven golden bowls full of the wrath of God, who lives forever and ever; 8 and the temple was filled with smoke from the glory of God and from his power, and no one could enter the temple until the seven plagues of the seven angels were ended.

Chapter fifteen provides a transition into the final cycle of plagues and a metaphorical telling of the collapse of the forces opposed to God’s will. The seven angels with the seven bowls should remind us of the seven angels with the seven trumpets in Revelation 8:6-11:13 and the seven seals in Revelation 6:1-8:5. Since the seven bowls are actually poured out in the following chapter I’ll look at the parallels between the bowls, trumpets and seals as well as the similarities with the plagues in Exodus at that point. For this brief chapter I’ll focus on this brief pause to worship prior to the unveiling of the judgment of God upon the earth.

Throughout Revelation there is this pause and restraint that interrupts the descent into judgment. While these portions of Revelation may not occupy the imaginative space of the horsemen of the apocalypse, the great dragon, the beasts and the numerous other images of the book of Revelation they are important to the rhythm and understanding of the book. Amid all the chaos that appears to be unleashed upon the earth they are continual reminders to the faithful that God is in control and that their faithful witness is how they will conquer the seemingly unconquerable forces that are arrayed against them. They will stand with Moses and the faithful of all ages proclaiming the praise of God and the Lamb.

The sea of glass follows the image of the rivers of blood up to the horse’s bridle, and as the faithful gather to sing the song of Moses and the song of the Lamb we are reminded of when Moses and Miriam and the people of God sang on the far side of the Red Sea as Pharaoh and his armies were submerged in the sea in Exodus 14. The song which the faithful sing is not the song of Moses, recorded in Exodus 15, even though it reflects some similar themes but instead the song of Moses and Lamb. The Lamb is joined to the messenger of God who told the people how to celebrate the first Passover. In the story of Exodus there is an extended pause for worship and ritual prior to the final judgment on Egypt. Here the faithful gather around the glass sea to sing songs of praise before the seven golden bowls are distributed.

The song reflects the most hopeful vision of the prophets where all nations will come and worship before God. Texts like Isaiah 2: 2-4, Isaiah 66: 23, Jeremiah 16:19 and Zechariah 8:22 all point hopefully to the time when all the earth realizes the Lordship of the Creator. A time when no one worships the beast or the dragon or any other idol, but all can realize that God alone is holy.

In Revelation 8: 3-5 the prayers of the saints are offered up with incense to God and earlier in Revelation 6:9-11 when the fifth seal was opened the martyrs had cried out “how long will it be before you judge the earth.” God sees, hears and now responds to this earlier offering. God’s wrath at those who have oppressed not only God’s people, but God’s creation will no longer be contained. Earlier the prayers of the faithful were offered on the altar, now from the temple come the seven bowls filled with God’s wrath.

The language of the temple of the tent of witnesses also harkens back to the tabernacle created for the journey through the wilderness. While earlier we have heard the temple referenced we now are referred to the central portion of a heavenly tabernacle. The tabernacle was built on a model given to Moses in the book of Exodus and many Jewish people believed it was an earthly model of God’s heavenly temple. Yet it is also the place of worship for a people and a God on the move and as the movement of Revelation continues we will see that God is on the move to have God’s kingdom dwell on earth. The tabernacle on earth and the tabernacle in heaven are temporary structures to serve until the time when there is no longer a need for a temple in the city of God for God dwells in the midst of the city.

 

Revelation 14 The Harvest of God

 Revelation 14

1 Then I looked, and there was the Lamb, standing on Mount Zion! And with him were one hundred forty-four thousand who had his name and his Father’s name written on their foreheads. 2 And I heard a voice from heaven like the sound of many waters and like the sound of loud thunder; the voice I heard was like the sound of harpists playing on their harps, 3 and they sing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the one hundred forty-four thousand who have been redeemed from the earth. 4 It is these who have not defiled themselves with women, for they are virgins; these follow the Lamb wherever he goes. They have been redeemed from humankind as first fruits for God and the Lamb, 5 and in their mouth no lie was found; they are blameless.

6 Then I saw another angel flying in midheaven, with an eternal gospel to proclaim to those who live on the earth — to every nation and tribe and language and people. 7 He said in a loud voice, “Fear God and give him glory, for the hour of his judgment has come; and worship him who made heaven and earth, the sea and the springs of water.”

8 Then another angel, a second, followed, saying, “Fallen, fallen is Babylon the great! She has made all nations drink of the wine of the wrath of her fornication.”

9 Then another angel, a third, followed them, crying with a loud voice, “Those who worship the beast and its image, and receive a mark on their foreheads or on their hands, 10 they will also drink the wine of God’s wrath, poured unmixed into the cup of his anger, and they will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb. 11 And the smoke of their torment goes up forever and ever. There is no rest day or night for those who worship the beast and its image and for anyone who receives the mark of its name.”

12 Here is a call for the endurance of the saints, those who keep the commandments of God and hold fast to the faith of Jesus.

13 And I heard a voice from heaven saying, “Write this: Blessed are the dead who from now on die in the Lord.” “Yes,” says the Spirit, “they will rest from their labors, for their deeds follow them.”

14 Then I looked, and there was a white cloud, and seated on the cloud was one like the Son of Man, with a golden crown on his head, and a sharp sickle in his hand! 15 Another angel came out of the temple, calling with a loud voice to the one who sat on the cloud, “Use your sickle and reap, for the hour to reap has come, because the harvest of the earth is fully ripe.” 16 So the one who sat on the cloud swung his sickle over the earth, and the earth was reaped.

17 Then another angel came out of the temple in heaven, and he too had a sharp sickle. 18 Then another angel came out from the altar, the angel who has authority over fire, and he called with a loud voice to him who had the sharp sickle, “Use your sharp sickle and gather the clusters of the vine of the earth, for its grapes are ripe.” 19 So the angel swung his sickle over the earth and gathered the vintage of the earth, and he threw it into the great wine press of the wrath of God. 20 And the wine press was trodden outside the city, and blood flowed from the wine press, as high as a horse’s bridle, for a distance of about two hundred miles.

The triumphant tone of this chapter can be both jubilant and unsettling. For those who have undergone suffering and who are awaiting God’s decisive action they perhaps hear the distant refrain of the new song of the 144,000 proclaiming the victory of the lamb and an end to their tribulations. Yet, the image of a bloody harvest and the trampling of the great wine press of the wrath of God highlights the destructive power of God. The chapter has a militant tone which echoes in the lyrics of Julia Ward Howe’s “Battle Hymn of the Republic”

Mine eyes have seen the glory of the coming of the Lord
He is trampling out the vintage where the grapes of wrath are stored
He hath loosed the faithful lightning of his terrible swift sword
His truth is marching on

There are a number of contrasts between this vision and the vision that immediately precedes it in Revelation 13: while the dragon may stand upon the seashore the lamb stands upon the high ground of Mount Zion; while those who worshipped the beast were marked with its number the followers of the lamb bear the name of God upon their foreheads; the previous chapter showed the social cost of not conforming to the demands of the beast (or the empire) while here conformity’s cost is revealed as drinking the undiluted wine of God’s wrath. The chapter also looks forward to remaining chapters of Revelation and tells through one set of images the judgment of Babylon (Rome) what will be developed in two additional sets of images in chapters 15-16 and chapters 17-18 respectively. Much like the dragon’s defeat in heaven foreshadows the final defeat in Revelation 20, here Rome’s derivative rule will be announced here but told through the story of the harlot and the beast in Revelation 17-18. For those who have waited for God’s action the time of their waiting has ended and the time open to the possibility of repentance is quickly closing as well.

The one hundred and forty-four thousand, introduced in chapter seven, are reintroduced here. The number is a number of completeness, twelve times twelve thousand, where every tribe of Israel is sealed. They are purchased or redeemed out of humanity as a first fruit of the larger harvest that is expected and which will happen metaphorically below. As chapter seven remined us they will eventually be a part of the multitude beyond counting of every language, tribe, nation and people. These one hundred forty-four thousand are described as male virgins who have no family commitments and are free to follow the lamb wherever he goes. The old nursery song is now reversed where instead of Mary having a little lamb who follows wherever she goes the Lamb of God has these men who follow it regardless of where it goes. The virginity of these first fruits of humankind may be literal representing people unencumbered by familial ties but it also may be metaphorical referring to those who have not compromised their relationship with God or indulged in practices which Revelation views as immoral. There is a parallel with how Jeremiah uses bridal imagery for Israel in Jeremiah 2: 2-3

Go and proclaim in the hearing of Jerusalem, “Thus says the LORD: I remember the devotion of your youth, your love as a bride, how you followed me in the wilderness, in a land not sown. Israel was holy to the LORD, the first fruit of his harvest. All who ate of it were held guilty; disaster came upon them.

The figures of the one hundred forty-four thousand as chaste males also contrasts them strongly with not only those who have compromised in their faith but also sets them diametrically against the way Revelation views Rome (Babylon). Now in a striking use of language reminiscent of Jeremiah 2, the one hundred forty-four thousand represent an Israel that has remained faithful and now instead of Israel ‘playing the whore’ it is Rome (Babylon) who has made the nations drink the ‘wine of her fornication.’ This also contrasts with the public image that post-Augustan Rome tried to craft for itself being a nation of piety and law. Revelation continues to unmask the true character of Rome from the perspective of the early followers of Christ.

Three angels come announcing an eternal gospel. While many people are used to the word gospel being used to describe books out of the bible or its typical English translation of ‘good news’ the Greek word euangellion which we translate as gospel typically in Roman culture a ‘gospel’ is a proclamation on behalf of the emperor. There were gospels proclaiming the celebration of a victory (proclaiming to a people conquered their liberation by the forces of Imperial Rome) or to celebrate a birth or birthday or assumption of power related to the emperor. The language of the early Christians is full of political implications but they are people whose allegiance is to Christ, which means Messiah or King, and not to Caesar. The gospel proclaimed here is truly good news for those whose allegiance has been to Christ and who have resisted accommodating to the ways of the empire, but for those whose allegiance rests with the beasts, wittingly or unwittingly, it is the announcement of judgment. The purpose of Revelation is to encourage those who are among the faithful to continue in their perseverance even in the midst of persecution and to trust that the time of God’s action is approaching. Here the faithful have their reward and rest announced while those who have allowed the beast to have their allegiance and worship must drink the cup that has been prepared for them.

Talking about the judgment of God or the wrath of God has become unpopular in many churches and yet it is an essential, if uncomfortable, thing for Christians and the church to wrestle with unless we also want to, often unwittingly and unthinkingly, proclaim a God who either is unable to help people in the midst of their struggles or who always stands on the side of the oppressor. Christianity and Judaism before it has always believed that God takes sides, that God acts, and that God expects certain things from those who become covenant partners with God. For me one of the passages that reoriented how I think about Revelation comes from Miroslav Volf’s Exclusion and Embrace

Most people who insist on God’s “nonviolence” cannot resist using violence themselves (or tacitly sanctioning its use by others). They deem the talk of God’s judgment irreverent, but think nothing of entrusting judgment into human hands, persuaded presumably that this is less dangerous and more humane than to believe in a God who judges! That we should bring “down the powerful from their thrones” (Luke 1: 51-52) seems responsible; the God should do the same, as the song of that revolutionary Virgin explicitly states, seems crude. And so, violence thrives, secretly nourished by belief in a God who refuses to wield the sword.

My thesis that the practice of nonviolence requires a belief in divine vengeance will be unpopular with many Christians, especially theologians in the West. To the person who is inclined to dismiss it, I suggest imagining that you are delivering a lecture in a war zone (which is where a paper that underlies this chapter was originally delivered). Among your listeners are people whose cities and villages have been first plundered, then burned and leveled to the ground, whose daughters and sisters have been raped, whose fathers and brothers have had their throats slit. The topic of the lecture: a Christian attitude toward violence. The thesis: we should not retaliate since God is perfect noncoercive love. Soon you would discover it takes the quiet suburban home for the birth of the thesis that human nonviolence corresponds to God’s refusal to judge. In a scorched land, soaked in the blood of the innocent, it will invariably die. And as one watches it die, one will do well to reflect about many other pleasant captivities of the liberal mind. (Volf, 1996, pp. 303-304)

The harvest image that concludes this chapter and foreshadows the narrative of the coming chapters. The first harvest can be read as either a positive or negative image. On the positive side the harvest of wheat, barley and other grains, which were typically harvested by the sickle, indicate the end of the growing season and the gathering of the long-awaited harvest into the barns. There is no indication of the sifting of the wheat away from the tares, only the ingathering of the grain. However, the two harvests can be read together as a common bloody harvest. The images do pair the Son of Man image from Daniel 7:13 with the language of the harvest of grain and the winepress in Joel 3: 13:

Put in the sickle, for the harvest is ripe. Go in, tread, for the wine press is full.
 The vats overflow, for their wickedness is great.

Yet, I do read the first harvest as a positive image. The first reaping brings together the harvest from across the earth. The second reaping comes from the temple, which in the next chapters will be a place where judgment will come from. Although grapes are not typically harvested with a sickle, Revelation continues the metaphor to describe the harvest of the vintage of the earth. The image ends with the winepress of the wrath of God and blood flowing for two hundred miles to the depth of a horse’s bridle. On first reading it is easy to think of the God who treads this winepress as a blood thirsty God and more like the beasts than the Lamb, and while those who have undergone oppression may want to see the blood of those who shed their blood I don’t believe that vengeance is the primary function of this image, instead it is unveiling the way things are. The image of God treading the winepress echoes the beginning of Isaiah 63: 1-6

“Who is this that comes from Edom, from Bozrah in garments stained crimson?
Who is this so splendidly robed marching in his great might?”
“It is I, announcing vindication, mighty to save.:
“Why are your robes red, and your garments like theirs who tread the wine press?”
“I have trodden the wine press alone, and from the peoples no one was with me;
I trod them in anger and trampled them in wrath; their juice spattered on my garments,and stained all my robes.
For the day of vengeance was in my heart, and the year for my redeeming work had come.
I looked and there was no helper; I stared, but there was no one to sustain me;
so my own arm brought me victory, and my wrath sustained me.
I trampled down peoples in my anger, I crushed them in my wrath,
and I poured out their lifeblood on the earth

As violent as this passage is, I always imagine tears in the eyes of the personified figure of the LORD treading the wine press alone, abandoned by the world. Anger and grief are frequently close cousins and the prophets often portray an image of a grieving and wounded God seeing the state of the world or the people of God and desiring a solution. I also think it is important to pay attention to the construction of the metaphor. Ultimately, I believe this passage, like several other places in Revelation are not about prophesying some horrific scene of judgement but rather about revealing the reality of the bloodshed already present in the world. God does not transform the juice of the grapes into something it was not but rather in the press shows what the harvest of the world is in contrast to the harvest of Christ that has been brought into the barns.   As Craig Koester can insightfully state:

This scene, as in 19: 11-21, envisions an end to the injustice that has plagued the world (cf. sec. 39 COMMENT). The river of blood, which flows as high as horse’s bridle, show the magnitude of the violence that has been done on earth (14:20). It reveals why divine justice cannot be delayed indefinitely. As Christ tramples the grapes, the amount of blood that is squeezed out shows how full of brutality the world has become. From this perspective the question is not, “Why is God’s judgment so severe?” Rather, if one sees the earth as a vineyard already filled with blood, the question is like that of the martyrs: “Why has God not judged the wicked sooner?” (6:10) (Koester, 2014, pp. 630-631)

God may have desired a different harvest from the vineyard than the bloody one which was reaped, God may have desired not to tread the winepress alone and yet, the bloodshed of the earth was present even when it was not unveiled. The cry of the martyrs, “How long, O Lord” has remained unanswered until this point in Revelation. From this chapter onward the answer of the Lord is, “I will wait no longer, the time of harvest has come.” And the eyes of those watching will see the glory and the terror of the coming of the Lord, for the glory of God reveals and confronts the terror of the way things are on the earth and will soon put an end to those who have used their power to oppress and destroy the earth.
