Jesus said: I am the bread of life. One who comes to me will never be hungry; one who believes in me will never thirst. (John 6)
Here a great mystery becomes visible. What little we give away multiplies. This is the way of God. This is also the way we are called to live our lives. The little love we have, the little knowledge we have...the little possessions we have are given to us as gifts of God to be given away.
