The coming of God is truly not only a joyous message, but is, first, frightful news for anyone who has a conscience. And only when we have felt the frightfulness of the matter can we know the incomparable favor. God comes in the midst of evil, in the midst of death, and judges the evil in us and in the world. And in judging it, he loves us, he purifies us, he sanctifies us, he comes to us with his grace and love. He makes us happy as only children can be happy.
-- Dietrich Bonhoeffer, God Is In The Manger
