"When Jesus had washed the disciples’ feet, he said to them: 'Amen, amen, I say to you, no slave is greater than his master nor any messenger greater than the one who sent him.'" Jn 13:16
When Jesus assumed the posture of a slave and washed the feet of his apostles, he startled them and us. That we ought to be kind to one another and welcoming to all, even our enemies, is clear, but that we should kneel down and wash others' feet made no sense at the time of Jesus and continues to feel alien to us. While we might offer someone access to a bathroom to refresh themselves, the idea of washing their feet would never occur to us.
In Jesus' day washing feet was common, but it was done by women and foreign slaves. Heads of household would never wash feet, and although many of the great figures of the Hebrew bible offered kind service to their friends and family, Jesus' willingness to stoop to wash his disciples feet signalled a new kind of leadership and a radical view of God. Jesus' challenge was clear. We must see ourselves as less in order that God can be more.
Today, think about the God in others, not your own power or prestige.
