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

“If we do an eye for an eye and a tooth for a tooth, we will be a blind and toothless nation.”

“Darkness cannot drive out darkness: only light can do that.”

“...and see ominous clouds of inferiority beginning to form in her little mental sky...”

“Take the first step in faith, you don't have to see the whole staircase, just take the first step.”

“Unity has never meant uniformity.”

“The church must be reminded that it is not the master or the servant of the state, but rather the conscience of the state. It must be the guide and the critic of the state, and never its tool. If the church does not recapture its prophetic zeal, it will become an irrelevant social club without moral or spiritual authority.”

“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.”

“We are going to win our freedom because both the sacred heritage of our nation and the eternal will of the Almighty God are embodied in our echoing demands. So however difficult it is during this period, however difficult it is to continue to live with the agony and the continued existence of racism, however difficult it is to live amidst the constant hurt, the constant insult and the constant disrespect, I can still sing we shall overcome. We shall overcome because the arc of the moral universe is long but it bends towards justice. We shall overcome because Carlisle is right. "No lie can live forever." We shall overcome because William Cullen Bryant is right. "Truth crushed to earth will rise again." We shall overcome because James Russell Lowell is right. "Truth forever on the scaffold, wrong forever on the throne."   Yet that scaffold sways the future. We shall overcome because the Bible is right.  "You shall reap what you sow." With this faith we will be able to hew out of the mountain of despair, a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to speed up the day when all of God's children all over this nation - black men and white men, Jews and Gentiles, Protestants and Catholics will be able to join hands and sing in the words of the old negro spiritual, "Free at Last, Free at Last, Thank God Almighty, We are Free At Last.”

“Of all the forms of inequality, injustice in health care is the most shocking and inhumane.”

“A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual doom.”

“I'm concerned about a better world. I'm concerned about justice; I'm concerned about brotherhood; I'm concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can't murder murder. Through violence you may murder a liar, but you can't establish truth. Through violence you may murder a hater, but you can't murder hate through violence. Darkness cannot put out darkness; only light can do that.”
