During the same meal, Jesus makes two startling announcements. Judas will betray him and Peter will deny knowing him. In both cases, Jesus has just washed their feet even though he knows what they will do. Although John doesn’t mention it, these pronouncements are made during the time when Jesus was establishing the Lord’s Supper (cf., Matthew 26, Mark 14, and Luke 22). When Jesus consecrated the cup for communion, he said, “This is my blood of the covenant, which is poured out for many for the forgiveness of sins” (Matthew 26:28). This story highlights how the love of Jesus is able to transcend our own human weaknesses.
Passage: John 13:18-38
