God's greatness is experienced in humble ways

When the Lord of the world comes and undertakes the slave's task of foot-washing - which is an illustration of the way he washes our feet all through our lives - we have a totally different picture. God doesn't want to trample on us but kneels down before us so as to exalt us. The mystery of the greatness of God is seen precisely in the fact that he can be small... Only when power is changed from the inside, and we accept Jesus and his way of life, whose whole self is there in the action of foot-washing, only then can the world be healed and the people be able to live at peace with one another.   Pope Benedict XVI
