The letter and spirit of scripture, and of all Christianity, forbid us to suppose that life in the New Creation (Heaven) will be a sexual life; and this reduces our imagination to the withering alternatives either of bodies which are hardly recognizable as human bodies at all or else of a perpetual fast. As regards to the fast, I think our present outlook might be like that of a small boy who, on being told that the sexual act was the highest bodily pleasure, should immediately ask whether you ate chocolates at the same time. On receiving the answer ‘No,’ he might regard [the] absence of chocolates as the chief characteristic of sexuality. In vain would you tell him that the reason why lovers in their raptures don’t bother about chocolates is that they have something better to think of. The boy knows chocolate: he does not know the positive thing that excludes it. We are in the same position. We know the sexual life; we do not know, except in glimpses, the other thing which, in Heaven, will leave no room for it.”
C.s. Lewis
