Luther and Lewis

This, then, is the meaning of these words of the Mother of God: “In all those great and good things there is nothing of mine, but He who alone does all things, and whose power works in all, has done such great things for me.”—Martin Luther, Magnificat AE 21:328

The moment you have a self at all, there is a possibility of putting your first—wanting to be the centre—wanting to be God, in fact. That was the sin of Satan: and that was the sin he taught the human race.—C. S. Lewis, Business of Heaven, p. 235.
