“What we do now echoes in eternity.”

As quoted in Pythagoron: The Religious, Moral, and Ethical Teachings of Pythagoras (1947) by Hobart Huson, p. 99
Context: There is no word or action but has its echo in Eternity.
Thought is an Idea in transit, which when once released, never can be lured back, nor the spoken word recalled. Nor ever can the overt act be erased All that thou thinkest, sayest, or doest bears perpetual record of itself, enduring for Eternity.

1960s, Letter from a Birmingham Jail (1963)
Context: I have no fear about the outcome of our struggle in Birmingham, even if our motives are at present misunderstood. We will reach the goal of freedom in Birmingham and all over the nation, because the goal of America is freedom. Abused and scorned though we may be, our destiny is tied up with America's destiny. Before the pilgrims landed at Plymouth, we were here. Before the pen of Jefferson etched the majestic words of the Declaration of Independence across the pages of history, we were here. For more than two centuries our forebears labored in this country without wages; they made cotton king; they built the homes of their masters while suffering gross injustice and shameful humiliation -and yet out of a bottomless vitality they continued to thrive and develop. If the inexpressible cruelties of slavery could not stop us, the opposition we now face will surely fail. We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands.

Context: Eternal life and eternal death; what do these words mean? This is the question that comes up again and again. It has recently been brought up by those whom I am appointed to instruct; and the question with its answer, brings new and fearful responsibility with every return. I am more and more convinced that the idea of duration is not the one that affects us most: for here it has proved that those who are least careful about what they are in heart and life, are trying hardest to convince themselves and others that the "doctrine of eternal punishment" is not true. By making themselves believe that to be the all-important question, they draw off their own and others' attention from the really momentous one, — "Am I living the eternal life? Is it begun in me now?"
And now I see why I have questioned whether it was right in me to express my own doubts of this very doctrine. The final renovation of all souls, their restoration to life in holiness and love, is certainly a hope of mine that is not without a strong infusion of confidence; but I dare not say it is a belief; because both reason and revelation have left it in deep mystery; and the expression of any such belief does not seem to me likely to help others much; certainly not those who are indolent or indifferent regarding the true Christian life.
Then the "loss of the soul" is in plain language spoken of by our Lord as possible. What can that mean, but the loss of life in Him? the loss of ennobling aspirations, of the love of all good, of the power of seeing and seeking truth? And if this is possible to us now, by our own choice, why not forever? — since, as free beings, our choice must always be in our own power?
The truth that we must all keep before us, in order to be growing better forever, is that life is love and holiness; death, selfishness and sin; then it is a question of life and death to be grappled with in the deep places of every soul.
