A threatening telephone call at midnight alarmed him: "Nigger, we are tired of you and your mess now. And if you aren't out of this town in three days, we're going to blow your brains out and blow up your house." Shaken, King went to the kitchen to pray. "I could hear an inner voice saying to me, 'Martin Luther, stand up for righteousness. Stand up for justice. Stand up for truth. And lo I will be with you, even until the end of the world.'"
