“All the gods are dead except the god of war.”

Sec. 125
The Gay Science (1882)
Context: God is dead! God remains dead! And we have killed him. How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives: who will wipe this blood off us? What water is there for us to clean ourselves? What festivals of atonement, what sacred games shall we have to invent? Is not the greatness of this deed too great for us? Must we ourselves not become gods simply to appear worthy of it?

The Quotable Sir John
Context: The question is not is there a God, but is there anything else except God? God is everyone and each of us is a little bit.

Context: Jesus said that God was not the God of the dead, but of the living. And the other life is not, in fact, thinkable to us except under the same forms as those of this earthly and transitory life.

Context: That God of the clergymen, He is for me as dead as a doornail. But am I an atheist for all that? The clergymen consider me as such — be it so; but I love, and how could I feel love if I did not live, and if others did not live, and then, if we live, there is something mysterious in that. Now call that God, or human nature or whatever you like, but there is something which I cannot define systematically, though it is very much alive and very real, and see, that is God, or as good as God. To believe in God for me is to feel that there is a God, not a dead one, or a stuffed one, but a living one, who with irresistible force urges us toward aimer encore; that is my opinion.

¶ 234 - 235.
An Humble, Earnest and Affectionate Address to the Clergy (1761)
Context: The eternal Son of God came into the world, only for the sake of this new birth, to give God the glory of restoring it to all the dead sons of fallen Adam. All the mysteries of this incarnate, suffering, dying Son of God, all the price that he paid for our redemption, all the washings that we have from his all-cleansing blood poured out for us, all the life that we receive from eating his flesh, and drinking his blood, have their infinite value, their high glory, and amazing greatness in this, because nothing less than these supernatural mysteries of a God-man, could raise that new creature out of Adam's death, which could be again a living temple, and deified habitation of the Spirit of God.
That this new birth of the Spirit, or the divine life in man, was the truth, the substance, and sole end of his miraculous mysteries, is plainly told us by Christ himself, who at the end of all his process on earth, tells his disciples, what was to be the blessed, and full effect of it, namely, that the Holy Spirit, the comforter (being now fully purchased for them) should after his ascension, come in the stead of a Christ in the flesh. "If I go not away," says he, "the comforter will not come; but if I go away, I will send him unto you, and he shall guide you into all truth." Therefore all that Christ was, did, suffered, dying in the flesh, and ascending into heaven, was for this sole end, to purchase for all his followers a new birth, new life, and new light, in and by the Spirit of God restored to them, and living in them, as their support, comforter, and guide into all truth. And this was his, "LO, I AM WITH YOU ALWAY, EVEN UNTO THE END OF THE WORLD.
