I knew before that God gave life to humankind and desires that they should live; now I understand more than that. I understand that God does not wish people to live apart, and therefore he does not reveal to them what each one needs for himself; but he wishes them to live united, and therefore reveals to each of them what is necessary for all. I now understand that though it seems to people that they live by care for themselves, in truth it is love alone by which they live. He who has love is in God, and God is in him, for God is love.
