Jesus was invited to dinner by a well-to-do gentleman, Simon the Pharasee, one day. The dinner party was crashed by a woman of rotten reputation. When Simon asked why Jesus did not rebuke this sinner-woman: Quit harrassing her! You invited Me to dinner, and didn't even provide a basin for Me to rinse My dusty feet, yet she has been washing them with her tears and drying them with her hair, and she has not stopped kissing them since she got in here. She loves much; she has been forgiven much. Those who are stingy with their love will receive stingy forgiveness .......
It wasn't all that much later
that Jesus brought His disciples together in a borrowed upstairs room in Jerusalem, not far from His mother's apartment. He took up a towel and basin, and got down on the floor, and performed that menial guest-service that was one of the less-enviable chores of the most junior house-servant, washing the dust and grime from their feet in those days of open sandals and dirt roads.
This is My command: that you love one another.
The one who would lead must be the servant of all, the slave of all.
