“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“A man who does not have something for which he is willing to die is not fit to live.”

“Agape does not begin by discriminating between worthy and unworthy people, or any qualities people possess. It begins by loving others for their sakes. It is an entirely “neighbor-regarding concern for others,” which discovers the neighbor in every man it meets. Therefore, agape makes no distinction between friend and enemy; it is directed toward both. If one loves an individual merely on account of his friendliness, he loves him for the sake of the benefits to be gained from the friendship, rather than for the friend’s own sake. Consequently, the best way to assure oneself that love is disinterested is to have love for the enemy-neighbor from whom you can expect no good in return, but only hostility and persecution.”

“Human progress never rolls in on the wheels of inevitability; it comes through the tireless efforts of [people] willing to be co-workers with God.”

“Si supiera que el mundo se acaba mañana, yo, hoy todavía, plantaría un árbol.”

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

“The end of life is not to be happy, nor to achieve pleasure and avoid pain, but to do the will of God, come what may.”

“One day we will learn that the heart can never be totally right when the head is totally wrong”

“An individual who breaks a law that conscience tells him is unjust, and who willingly accepts the penalty of imprisonment in order to arouse the conscience of the community over its injustice, is in reality expressing the highest respect for the law”

“A genuine leader is not a searcher for consensus but a molder of consensus.” 

“Not everybody can be famous but everybody can be great, because greatness is determined by service.”

“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.”

“When religion becomes so involved in a future good "over yonder" that it forgets the present evils over here it is as dry as dust religion and needs to be condemned.”

“The amazing aftermath of Birmingham, the sweeping Negro Revolution, revealed to people all over the land that there are no outsiders in all these fifty states of America. When a police dog buried his fangs in the ankle of a small child in Birmingham, he buried his fangs in the ankle of every American. The bell of man's inhumanity to man does not toll for any one man. It tolls for you, for me, for all of us.”

“I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident, that all men are created equal." I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. 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. I have a dream today! I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of "interposition" and "nullification" -- one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today! I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight; "and the glory of the Lord shall be revealed and all flesh shall see it together.”
