“Life’s persistent and most urgent question is ‘What are you doing for others?’ ”

“Whenever men and women straighten their backs up, they are going somewhere, because a man can't ride your back unless it is bent”

“Hate destroys the hater...”

“What is more tragic than to see a person who has risen to the disciplined heights of tough-mindedness but has at the same time sunk to the passionless depths of hard-heartedness?”

“If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music, sweep streets like Leontyne Price sings before the Metropolitan Opera. Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the hosts of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well. If you can't be a pine at the top of the hill, be a shrub in the valley. Be be the best little shrub on the side of the hill.”

“So I say to you, seek God and discover him and make him a power in your life. Without him all of our efforts turn to ashes and our sunrises into darkest nights. Without him, life is a meaningless drama with the decisive scenes missing. But with him we are able to rise from the fatigue of despair to the buoyancy of hope. With him we are able to rise from the midnight of desperation to the daybreak of joy. St. Augustine was right—we were made for God and we will be restless until we find rest in him.”

“We have, it seems, shut the poor out of our minds and driven them from the mainstream of our society. We have allowed the poor to become invisible, and we have become angry when they make their presence felt. But just as nonviolence has exposed the ugliness of racial injustice, we must now find ways to expose and heal the sickness of poverty—not just its symptoms, but its basic causes.”

“Something is happening in Memphis; something is happening in our world. And you know, if I were standing at the beginning of time, with the possibility of taking a kind of general and panoramic view of the whole of human history up to now, and the Almighty said to me, "Martin Luther King, which age would you like to live in?" I would take my mental flight by Egypt and I would watch God's children in their magnificent trek from the dark dungeons of Egypt through, or rather across the Red Sea, through the wilderness on toward the promised land. And in spite of its magnificence, I wouldn't stop there. I would move on by Greece and take my mind to Mount Olympus. And I would see Plato, Aristotle, Socrates, Euripides and Aristophanes assembled around the Parthenon. And I would watch them around the Parthenon as they discussed the great and eternal issues of reality. But I wouldn't stop there. I would go on, even to the great heyday of the Roman Empire. And I would see developments around there, through various emperors and leaders. But I wouldn't stop there. I would even come up to the day of the Renaissance, and get a quick picture of all that the Renaissance did for the cultural and aesthetic life of man. But I wouldn't stop there. I would even go by the way that the man for whom I am named had his habitat. And I would watch Martin Luther as he tacked his ninety-five theses on the door at the church of Wittenberg. But I wouldn't stop there. I would come on up even to 1863, and watch a vacillating President by the name of Abraham Lincoln finally come to the conclusion that he had to sign the Emancipation Proclamation. But I wouldn't stop there. I would even come up to the early thirties, and see a man grappling with the problems of the bankruptcy of his nation. And come with an eloquent cry that we have nothing to fear but "fear itself." But I wouldn't stop there.”

“now is the time to make justice a reality for all God’s children.”

“On the parable of the Good Samaritan: "I imagine that the first question the priest and Levite asked was: 'If I stop to help this man, what will happen to me?' But by the very nature of his concern, the good Samaritan reversed the question: 'If I do not stop to help this man, what will happen to him?”

“You are not only responsible for what you say, but also for what you do not say”

“As if the weight of such a commitment to life and health of America were not enough, another burden of responsibility was placed upon me in 1964; and I cannot forget that the Nobel Peace Prize was also a commission, a commission to work harder than I had ever worked before for the brotherhood of man. This is a calling that takes me beyond national allegiances.”

“The richer we have become materially, the poorer we become morally and spiritually. We have learned to fly in the air like birds and swim in the sea like fish, but we have not learned the simple art of living together as brothers.”

“[God] seeks us in dark places and suffers with us in our tragic prodigality.”

“we must constantly build dykes of courage to hold back the flood of fear”
