“And when you discover what you will be in your life, set out to do it as if God Almighty called you at this particular moment in history to do it. Don’t just set out to do a good job. Set out to do such a good job that the living, the dead or the unborn couldn’t do it any better. 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.”

“We must live together as brothers or perish together as fools.”

“We must accept finite disappointment, but never lose infinite hope.”

“The time is always right, to do what's right.”

“We are called to speak for the weak, for the voiceless, for the victims of our nation, and for those it calls enemy, for no document from human hands can make these humans any less our brothers.”

“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.”

“Violence brings only temporary victories; violence, by creating many more social problems than it solves, never brings permanent peace.”

“Like anybody, I would like to have a long life. Longevity has its place. But I'm not concerned about that now. I just want to do God's will.”

“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. We must speak with all the humility that is appropriate to our limited vision, but we must speak.”

“Any religion that professes to be concerned with the souls of men and is not concerned with the slums that damn them, the economic conditions that strangle them and the social conditions that cripple them is a dry-as-dust religion.”

“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.”

“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.”

“If a man is called to be a street sweeper, he should sweep streets even as a Michaelangelo painted, or Beethoven composed music or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, 'Here lived a great street sweeper who did his job well.”

“«La oscuridad no puede conducirte fuera de la oscuridad: sólo la luz puede hacer eso. El odio no puede conducirte fuera del odio; sólo el amor puede hacer eso»”

“When people are voiceless, they will have temper tantrums like a child who has not been paid attention to. And riots are massive temper tantrums from a neglected and voiceless people.”
