Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction. So when Jesus says “Love your enemies,” he is setting forth a profound and ultimately inescapable admonition. Have we not come to such an impasse in the modern world that we must love our enemies– or else? The chain reaction of evil–hate begetting hate, wars producing wars–must be broken, or we shall be plunged into the dark abyss of annihilation.
Dr. Martin Luther King Jr, The Strength to Love
I’m concerned about a better world. I’m concerned about justice; I’m concerned about brotherhood; I’m concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can’t murder murder. Through violence you may murder a liar, but you can’t establish truth. Through violence you may murder a hater, but you can’t murder hate through violence. Darkness cannot put out darkness; only light can do that.
