"To be useful as a Christian, a man must keep himself free from all malign feelings, from all bitterness of resentment. Even righteous indignation must not drag Love from her throne. Over all the soul's passions Love must preside in serene majesty. The Christian worker must learn (and the sooner the better) if he has not already learned, that there is something better for a Christian than to plan revenge, and nurse resentment, and call down fire from heaven, even on those who show themselves base and unworthy."
