C S Lewis to MARY WILLIS SHELBURNE: On the resurrection of the body and of all creation; and on the goodness of the bodies we now have.26 November 1962
My stuff about animals came long ago in The Problem of Pain. I ventured the supposal—it could be nothing more—that as we are raised in Christ, so at least some animals are raised in us. Who knows, indeed, but that a great deal even of the inanimate creation is raised in the redeemed souls who have, during this life, taken its beauty into themselves? That may be the way in which the ‘new heaven and the new earth’ are formed. Of course we can only guess and wonder.
But these particular guesses arise in me, I trust, from taking seriously the resurrection of the body: a doctrine which now-a- days is very soft pedalled by nearly all the faithful—to our great impoverishment. Not that you and I have now much reason to rejoice in having bodies! Like old automobiles, aren’t they? where all sorts of apparently different things keep going wrong, but what they add up to is the plain fact that the machine is wearing out. Well, it was not meant to last forever.
Still, I have a kindly feeling for the old rattle-trap. Through it God showed me that whole side of His beauty which is embodied in colour, sound, smell and size. No doubt it has often led me astray: but not half so often, I suspect, as my soul has led it astray. For the spiritual evils which we share with the devils (pride, spite) are far worse than what we share with the beasts: and sensuality really arises more from the imagination than from the appetites: which, if left merely to their own animal strength, and not elaborated by our imagination, would be fairly easily managed. But this is turning into a sermon!
