JESUS humbled HIMSELF and washed the feet of the 12 desciples (including Judas; the one JESUS knew would betray HIM). Let us do our best to show love to everyone, remembering that we ourselves are not perfect.
"This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. Dear friends, since God so loved us, we also ought to love one another. No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us."
1 John 4:10-12 (NIV)
