“Now there is a final reason I think that Jesus says, ‘Love your enemies.’ It is this: that love has within it a redemptive power. And there is a power there that eventually transforms individuals. That’s why Jesus says, ‘Love your enemies.’ Because if you hate your enemies, you have no way to redeem and to transform your enemies. But if you love your enemies, you will discover that at the very root of love is the power of redemption. You just keep loving people and keep loving them, even though they’re mistreating you. Here’s the person who is a neighbor, and this person is doing something wrong to you and all of that. Just keep being friendly to that person. Keep loving them. Don’t do anything to embarrass them. Just keep loving them, and they can’t stand it too long. Oh, they react in many ways in the beginning. They react with bitterness because they’re mad because you love them like that. They react with guilt feelings, and sometimes they’ll hate you a little more at that transition period, but just keep loving them. And by the power of your love they will break down under the load. That’s love, you see. It is redemptive, and this is why Jesus says love. There’s something about love that builds up and is creative. There is something about hate that tears down and is destructive. So love your enemies.
I think of one of the best examples of this. We all remember the great president of this United States, Abraham Lincoln—these United States rather. You remember when Abraham Lincoln was running for president of the United States, there was a man who ran all around the country talking about Lincoln. He said a lot of bad things about Lincoln, a lot of unkind things. And sometimes he would get to the point that he would even talk about his looks, saying, ‘You don’t want a tall, lanky, ignorant man like this as the president of the United States.’ He went on and on and on and went around with that type of attitude and wrote about it. Finally, one day Abraham Lincoln was elected president of the United States. And if you read the great biography of Lincoln, if you read the great works about him, you will discover that as every president comes to the point, he came to the point of having to choose a Cabinet. And then came the time for him to choose a Secretary of War. He looked across the nation, and decided to choose a man by the name of Mr. Stanton. And when Abraham Lincoln stood around his advisors and mentioned this fact, they said to him: ‘Mr. Lincoln, are you a fool? Do you know what Mr. Stanton has been saying about you? Do you know what he has done, tried to do to you? Do you know that he has tried to defeat you on every hand? Do you know that, Mr. Lincoln? Did you read all of those derogatory statements that he made about you?’ Abraham Lincoln stood before the advisors around him and said: ‘Oh yes, I know about it; I read about it; I’ve heard him myself. But after looking over the country, I find that he is the best man for the job.'”
