1960s, I've Been to the Mountaintop (1968)
Context: Well, I don't know what will happen now. We've got some difficult days ahead. But it doesn't matter with me now. Because I've been to the mountaintop. And I don't mind. Like any man, I would like to live a long life. Longevity has its place. But I'm not concerned about that now. I just want to do God's will. And He's allowed me to go up to the mountain. And I've looked over. And I've seen the promised land. I may not get there with you. But I want you to know tonight, that we, as a people will get to the promised land. And I'm happy, tonight. I'm not worried about anything. I'm not fearing any man. Mine eyes have seen the glory of the coming of the Lord.

1960s, Beyond Vietnam: A Time to Break Silence (1967)
Context: A genuine revolution of values means in the final analysis that our loyalties must become ecumenical rather than sectional. Every nation must now develop an overriding loyalty to mankind as a whole in order to preserve the best in their individual societies. This call for a worldwide fellowship that lifts neighborly concern beyond one's tribe, race, class, and nation is in reality a call for an all-embracing and unconditional love for all mankind. This oft misunderstood, this oft misinterpreted concept, so readily dismissed by the Nietzsches of the world as a weak and cowardly force, has now become an absolute necessity for the survival of man. When I speak of love I am not speaking of some sentimental and weak response. I am not speaking of that force which is just emotional bosh. I am speaking of that force which all of the great religions have seen as the supreme unifying principle of life. Love is somehow the key that unlocks the door which leads to ultimate reality.

Variants (Many of MLKs' speeches were delivered many times with slight variants): An Individual has not started living fully until they can rise above the narrow confines of individualistic concerns to the broader concerns of humanity. Every person must decide at some point, whether they will walk in light of creative altruism or in the darkness of destructive selfishness. This is the judgment: Life's most persistent and urgent question is: 'What are you doing for others?'

"The Reasons for My Involvement in the Peace Movement" (1972) http://www.shalomctr.org/node/61; later included in Moral Grandeur and Spiritual Audacity (1996)
Context: There is immense silent agony in the world, and the task of man is to be a voice for the plundered poor, to prevent the desecration of the soul and the violation of our dream of honesty.
The more deeply immersed I became in the thinking of the prophets, the more powerfully it became clear to me what the lives of the Prophets sought to convey: that morally speaking, there is no limit to the concern one must feel for the suffering of human beings, that indifference to evil is worse than evil itself, that in a free society, some are guilty, but all are responsible.

To the ancients the hearth was sacred; beside the hearth they erected their lares and household-gods. Let us also hold the hearth sacred, where the conscientious German housewife slowly sacrifices her life, to keep the home comfortable, the table well supplied, and the family healthy."

About

“He took his way to the abode of sacred Loyalty, seeking to discover her hidden purpose. It chanced that the goddess, who loves solitude, was then in a distant region of heaven, pondering in her heart the high concerns of the gods. Then he who gave peace to Nemea accosted her thus with reverence: "Goddess more ancient than Jupiter, glory of gods and men, without whom neither sea nor land finds peace, sister of Justice…"”
