“Man depends on God for all things: God depends on man for one. Without man's love God does not exist as God, only as creator, and love is the one thing no one, not even God himself, can command. It is a free gift or it is nothing. And it is most itself, most free, when it is offered in spite of suffering, of injustice, and of death . . . The justification of the injustice of the universe is not our blind acceptance of God's inexplicable will, nor our trust in God's love, his dark and incomprehensible love, for us, but our human love, notwithstanding anything, for him.”
