It's not only necessary to know how to go about loving your enemies, but also to go down into the question of why we should love our enemies. I think the first reason that we should love our enemies, and I think this was at the very center of Jesus' thinking, is this: that hate for hate only intensifies the existence of hate and evil in the universe. If I hit you and you hit me and I hit you back and you hit me back and go on, you see, that goes on ad infinitum. It just never ends. Somewhere somebody must have a little sense, and that's the strong person. The strong person is the person who can cut off the chain of hate, the chain of evil.
