Joh 13:11 Because he had known his betrayer. This is why he said, “Not all of you are clean.”
Joh 13:12 When he had washed their feet and put on his outer clothes, he reclined again and said to them, “Do you know what I was doing for you?
Joh 13:13 You are calling me the Teacher and the Lord– and you are speaking accurately, since that is what I am.
Joh 13:14 So if I, the Lord and Teacher, have washed your feet, you also should wash one another’s feet.
Worship by washing
The point of Jesus’ example for his disciples was not to inaugurate a new ritual for the church. There is nothing wrong with foot-washing. I used to do it for the outgoing interns at bible college every year. It is an effective way to model humble service toward one another.
But Jesus is using this event to show his disciples that the best way they can show their appreciation for who he is is to treat each other with kindness and self-sacrifice. Worshiping Christ is more than something we do by coming to church. We also worship Christ by serving others who are part of his body.
Lord, expand the parameters of our worship.
