C.S. Lewis:
We are all receiving Charity. There is something in each of us that cannot be naturally loved. It is no one’s fault if they do not so love it … You might as well ask people to like the taste of rotten bread or the sound of a mechanical drill. We can be forgiven, and pitied, and loved in spite of it, with Charity; no other way. All who have good parents, wives, husbands, or children, may be sure that at some times — and perhaps at all times in respect of some one particular trait or habit — they are receiving Charity, are loved not because they are lovable but because Love Himself [Christ] is in those who love them.
