The greatest challenge of the day is: how to bring about a revolution of the heart, a revolution which has to start with each one of us. When we begin to take the lowest places, to wash the feet of others, to love our brothers with that burning love, that passion which led to the cross, then we can truly say, 'Now I have begun'.
