NOTES for Joh 13:1-20
Peter and the other apostles were naturally embarrassed. No wonder: the King of Israel was washing their feet, doing a slave's work! Many of us would surely dislike it if the person dearest to us began doing something humiliating and improper. But this washing of feet is a decisive moment in the history of Jesus' relationship with His disciples; anyone who dislikes it is free to leave.
Why is it so important? Apparently it is impossible to understand the Lord and follow Him without learning through experience this lesson in which the Master serves those beneath Him and the Teacher serves His disciples. As Scripture says, this is an example—but not an example on a board or in a picture. Peter and all of us must pass through this shock so that we will never again be shocked by the thought that we too must serve those who are lesser and weaker than we are.
