I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
We must develop and maintain the capacity to forgive. He who is devoid of the power to forgive is devoid of the power to love. There is some good in the worst of us and some evil in the best of us. When we discover this, we are less prone to hate our enemies.
