Submission
In John 13, Jesus washes the disciples’ feet. It’s a well-known story, a frequently referenced model for Christ’s attitude of humble service to others. But there’s another side to the story.
Foot-washing requires a foot to wash.
In the story, Peter initially refuses to allow his friend and teacher to perform such a menial, degrading task. Jesus replies that submission isn’t optional—it’s an essential element in the interaction.
I don’t think that’s an accident. You can’t force someone to receive an expression of intimacy. If it’s a true act of humble service, the one whose feet are washed must submit.
