The worldly man treats certain people kindly because he ‘likes’ them: the Christian, trying to treat every one kindly, finds himself liking more and more people as he goes on—including people he could not even have imagined himself liking at the beginning.

Context

“Consequently, though Christian charity sounds a very cold thing to people whose heads are full of sentimentality, and though it is quite distinct from affection, yet it leads to affection. The difference between a Christian and a worldly man is not that the worldly man has only affections or ‘likings’ and the Christian has only ‘charity’. The worldly man treats certain people kindly because he ‘likes’ them: the Christian, trying to treat every one kindly, finds himself liking more and more people as he goes on—including people he could not even have imagined himself liking at the beginning. This same spiritual law works terribly in the opposite direction. The Germans, perhaps, at first ill-treated the Jews because they hated them: afterwards they hated them much more because they had ill-treated them.” source
