“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.”

“Nothing worthwhile is gained without sacrifice.”

“Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly, affects all indirectly.”

“The time comes when silence is betrayal. That time has come for us today...  ...some of us who have already begun to break the silence of the night have found that the calling to speak is often a vocation of agony, but we must speak.”

“I am convinced that love is the most durable power in the world. It is not an expression of impractical idealism, but of practical realism. Far from being the pious injunction of a Utopian dreamer, love is an absolute necessity for the survival of our civilization. To return hate for hate does nothing but intensify the existence of evil in the universe. Someone must have sense enough and morality enough to cut off the chain of hate and evil, and this can only be done through love.” — Martin Luther King Jr.”

“Just as Socrates felt that it was necessary to create a tension in the mind so that individuals could rise from the bondage of myths and half-truths to the unfettered realm of creative analysis and objective appraisal, so must we see the need for nonviolent gadflies to create the kind of tension in society that will help men rise from the dark depths of prejudice and racism to majestic heights of understanding and brotherhood.”

“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.”

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

“Power at its best is love implementing the demands of justice. Justice at its best is love correcting everything that stands against love.”

“A true revolution of values will soon cause us to question the fairness and justice of many of our past and present policies. On the one hand we are called to play the good Samaritan on life’s roadside; but that will be only an initial act. One day we must come to see that the whole Jericho road must be transformed so that men and women will not be constantly beaten and robbed as they make their journey on life’s highway. True compassion is more than flinging a coin to a beggar; it is not haphazard and superficial. It comes to see that an edifice which produces beggars needs restructuring. A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will look across the seas and see individual capitalists of the West investing huge sums of money in Asia, Africa and South America, only to take the profits out with no concern for the social betterment of the countries, and say: “This is not just.” It will look at our alliance with the landed gentry of Latin America and say: “This is not just.” The Western arrogance of feeling that it has everything to teach others and nothing to learn from them is not just. A true revolution of values will lay hands on the world order and say of war: “This way of settling differences is not just.” This business of burning human beings with napalm, of filling our nation’s homes with orphans and widows, of injecting poisonous drugs of hate into veins of people normally humane, of sending men home from dark and bloody battlefields physically handicapped and psychologically deranged, cannot be reconciled with wisdom, justice and love. A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death.”

“All of the people of the world cannot do the so-called big things. Some of us will have to be content doing the so-called little things, but we must do the little things in a big way. We must do the ordinary things in an extraordinary manner. And we must overcome our sense of inferiority by doing just this - by somehow accepting that we have to do and doing that well”

“No one really knows why they are alive until they know what they'd die for.”

“If you haven't found something you're willing to die for, than you don't deserve to live”

“Worship at its best is a social experience with people of all levels of life coming together to realize their oneness and unity under God. Whenever the church, consciously or unconsciously caters to one class it loses the spiritual force of the "whosoever will, let him come, doctrine and is in danger of becoming a little more than a social club with a thin veneer of religiosity.”

“If it falls to your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music ... Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the host of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well.”
