“"Faith mountains move" I hear: I see the practice of the world unheed
The foolish vaunt, the blatant boast that serves our vanity to feed. "Faith stands unmoved"; and why? Because man's silly fancies still remain,
And will remain till wiser man the day-dreams of his youth disdain.”

1960s, Cobo Center speech (1963)
Context: I go back to the South not with a feeling that we are caught in a dark dungeon that will never lead to a way out. I go back believing that the new day is coming. And so this afternoon, I have a dream. It is a dream deeply rooted in the American dream.
I have a dream that one day, right down in Georgia and Mississippi and Alabama, the sons of former slaves and the sons of former slave owners will be able to live together as brothers.
I have a dream this afternoon, I have a dream that one day, one day little white children and little Negro children will be able to join hands as brothers and sisters.
I have a dream this afternoon that one day, that one day men will no longer burn down houses and the church of God simply because people want to be free.
I have a dream this afternoon, I have a dream, that there will be a day that we will no longer face the atrocities that Emmett Till had to face or Medgar Evers had to face, that all men can live with dignity.
I have a dream this afternoon that my four little children, that my four little children will not come up in the same young days that I came up within, but they will be judged on the basis of the content of their character, not the color of their skin.
I have a dream this afternoon that one day right here in Detroit, Negroes will be able to buy a house or rent a house anywhere that their money will carry them and they will be able to get a job.
Yes, I have a dream this afternoon that one day in this land the words of Amos will become real and "justice will roll down like waters, and righteousness like a mighty stream."
I have a dream this evening that one day we will recognize the words of Jefferson that "all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." I have a dream this afternoon.
I have a dream that one day every valley shall be exalted, and "every valley shall be exalted, and every hill shall be made low; the crooked places shall be made straight, and the rough places plain; and the glory of the Lord shall be revealed, and all flesh shall see it together."
I have a dream this afternoon that the brotherhood of man will become a reality in this day.
And with this faith I will go out and carve a tunnel of hope through the mountain of despair. With this faith, I will go out with you and transform dark yesterdays into bright tomorrows. With this faith, we will be able to achieve this new day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing with the Negroes in the spiritual of old: "Free at last! Free at last! Thank God almighty, we are free at last!"

1960s, Discerning the Signs of History (1964)
Context: I'm tellin' yuh this morning, money can't save yuh. A beautiful home can't save yuh. Beautiful automobiles can't save yuh. It's God that will save us in the final analysis. And I say to this morning that history is teaching us a lesson. And I hope that we will see it. That there must be underneath all of our wills, underneath all of our material attainment, a moral and religious undergirding that will help us to know that God is our father. That he made us and that we are dependent on Him, and Him only, and when we see that, we have something. For we can arise from the fatigue of despair to the bouyancy of hope.
Dark yesterday can be transformed into bright tomorrow. When you know God, you can stand up amid the agonies and burdens of life and not despair. When you know God, you can stand up amid tension and tribulation and yet smile in the process. When you know God, you go on livin' anyhow. Nothin's gonna stop you 'cause you know that God is watching in your heart. When you know God, you have on some shoes that can help you walk through any muddy place. When you know God, you know that He is over everything. That [he]'s a rock in a weary land, that he is a shelter in the time of a storm. … When you know God, you can live and never die. We're gonna open the doors of the church, now, somebody here needs to accept the Christ. Somebody needs to come this morning. Discerning the signs of history. And as we sing who this morning will make that step. Remain true to the faith of our fathers. Somebody needs to decide Now. Who will come. When we sing will you make that step.

Australians in a Nuclear War (1983)
Context: The spirit may triumph where politics (the League and the United Nations), socio-political faiths such as Marxism, Italian Fascism and German National-Socialism — all have failed. I see our only hope in faith, charity, and in humbling ourselves before man and God.

The Faith that Heals (1910)
Context: Nothing in life is more wonderful than faith — the one great moving force which we can neither weigh in the balance nor test in the crucible. Intangible as the ether, ineluctable as gravitation, the radium of the moral and mental spheres, mysterious, indefinable, known only by its effects, faith pours out an unfailing stream of energy while abating nor jot nor tittle of its potency. Well indeed did St. Paul break out into the well-known glorious panegyric, but even this scarcely does justice to the Hertha of the psychical world, distributing force as from a great storage battery without money and without price to the children of men.
Three of its relations concern us here. The most active manifestations are in the countless affiliations which man in his evolution has worked out with the unseen, with the invisible powers, whether of light or of darkness, to which from time immemorial he has erected altars and shrines. To each one of the religions, past or present, faith has been the Jacob's ladder. Creeds pass, an inexhaustible supply of faith remains, with which man proceeds to rebuild temples, churches, chapels and shrines.
