Now for the few moments left, let us move from the practical how to the theoretical why. 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. [tapping on pulpit] 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. And that is the tragedy of hate, that it doesn't cut it off. It only intensifies the existence of hate and evil in the universe. Somebody must have religion enough and morality enough to cut it off and inject within the very structure of the universe that strong and powerful element of love.

I think I mentioned before that sometime ago my brother and I were driving one evening to Chattanooga, Tennessee, from Atlanta. He was driving the car. And for some reason the drivers were very discourteous that night. They didn't dim their lights; hardly any driver that passed by dimmed his lights. And I remember very vividly, my brother A. D. looked over and in a tone of anger said: "I know what I'm going to do. The next car that comes along here and refuses to dim the lights, I'm going to fail to dim mine and pour them on in all of their power." And I looked at him right quick and said: "Oh no, don't do that. There'd be too much light on this highway, and it will end up in mutual destruction for all. Somebody got to have some sense on this highway."

Somebody must have sense enough to dim the lights, and that is the trouble, isn't it? That as all of the civilizations of the world move up the highway of history, so many civilizations, having looked at other civilizations that refused to dim the lights, and they decided to refuse to dim theirs. And Toynbee tells that out of the twenty-two civilizations that have risen up, all but about seven have found themselves in the junkheap of destruction. It is because civilizations fail to have sense enough to dim the lights. And if somebody doesn't have sense enough to turn on the dim and beautiful and powerful lights of love in this world, the whole of our civilization will be plunged into the abyss of destruction. And we will all end up destroyed because nobody had any sense on the highway of history. Somewhere somebody must have some sense. Men must see that force begets force, hate begets hate, toughness begets toughness. And it is all a descending spiral, ultimately ending in destruction for all and everybody. Somebody must have sense enough and morality enough to cut off the chain of hate and the chain of evil in the universe. And you do that by love.
