It is more abstract this week, if you want images for the Sermon on the Mount in General look back at the Fourth Sunday after Epiphany. This week is Matthew 5: 13-20: Jesus telling the disciples they are the salt of the earth, light on a lampstand, a city on a hill and unless their righteousness exceeds that of the Pharisees they will not enter the kingdom of heaven.
More of an abstract image, but I found it helpful for my own meditation
A reminder that in the ancient world (pre-refrigerators) salt was mainly a preservative rather than a seasoning
