[S]omething inside us, the feeling of resentment, the feeling that wants to get one's own back, must be simply killed. I do not mean that anyone can decide this moment that he will never feel it anymore. That is not how things happen. I mean that every time it bobs its head up, day after day, year after year, all our lives long, we must hit it on the head. It is hard work, but the attempt is not impossible.
C. S. LewisThe worldly man treats certain people kindly because he 'likes' them: the Christian, trying to treat every one kindly, finds him liking more and more people as he goes on - including people he could not even have imagined himself liking at the beginning.
C. S. LewisIt is quite useless knocking at the door of heaven for earthly comfort. It's not the sort of comfort they supply there.
C. S. LewisWe may give our human loves the unconditional allegiance which we owe only to God. They they become gods: then they become demons. Then they will destroy us, and also destroy themselves. For natural loves that are allowed to become gods do not remain loves. They are still called so, but can become in fact complicated forms of hatred.
C. S. Lewis
