“Brothers, what we do in life, echoes in eternity.”

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.

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.

As quoted in Richard Nixon's First Inaugural Address (20 January 1969)

Context: Now then, Nick, wilt thou not sleep?
Nicholas glanced up from the plaquette on which he had been studying the Pali canon of Buddha’s teachings. He sighed and set it aside...
You don’t look like revelation has struck you, somehow.
No, Spirit.
This ain’t any better than the Tao?
No.
Nor the Bhagavad Gita? Nor the Avesta, neither?
No.
I thought certain you’d like them Gnostic Gospels.
Nicholas shrugged.
And I reckon you ain’t even looked at that nice book on Vodou.
Spirit, this is futility. What do the best of them but recapitulate the Ten Commandments, in one form or another? And I find no proof that men have obeyed strange gods any better than the God of the Israelites, or learned any more of the true nature of the Almighty. Shall I worship a cow? Shall I spin paper prayers on a wheel? I’d as lief go back to eating fish in Lent lest God smite me down, or pray to wooden Mary to take away the toothache.
Well, son, allowing for the foolishness, which I reckon depends on what port you hail from—ain’t there any one seems better than the rest?
None, Spirit. That I must be kind and do no harm, I needed no prophets to tell me; but not one will open his dead mouth to say what kind and harmless Lord would create this dreadful world, said Nicholas...
What do I tell my boy, then, if he gets the shakes about eternal life?
Set up no gods for thine Alec, Spirit. Nicholas lay back and put his arms about Mendoza, pulling her close. There is love, or there is nothing. The rest is vanity.
