“The people who keep on asking if they can’t lead a decent life without Christ, don’t know what life is about; if they did they would know that ’a decent life’ is mere machinery compared with the thing we men are really made for. Morality is indispensable; but the Divine Life, which gives itself to us and which calls us to be gods, intends for us something in which morality will be swallowed up. We are to be re-made. All the rabbit in us is to disappear–the worried, conscientious, ethical rabbit as well as the cowardly and sensual rabbit. We shall bleed and squeal as the handfuls of fur come out; and then, surprisingly, we shall find underneath it all a thing we have never yet imagined: a real Man, an ageless god, a son of God, strong, radiant, wise, beautiful, and drenched in joy.”
C.S. Lewis, Man or Rabbit?
This stripping off of the flesh is precisely what happened to Eustace during an encounter with Aslan in The Voyager of the Dawn Treader, one of the Narnia books.
