“Do your duty, and leave the rest to heaven.”

Jean-Christophe (1904 - 1912), Journey's End: The Burning Bush (1911)
Context: "Thou art not alone, and thou dost not belong to thyself. Thou art one of My voices, thou art one of My arms. Speak and strike for Me. But if the arm be broken, or the voice be weary, then still I hold My ground: I fight with other voices, other arms than thine. Though thou art conquered, yet art thou of the army which is never vanquished. Remember that and thou wilt fight even unto death."
"Lord, I have suffered much!"
"Thinkest thou that I do not suffer also? For ages death has hunted Me and nothingness has lain in wait for Me. It is only by victory in the fight that I can make My way. The river of life is red with My blood."
"Fighting, always fighting?"
"We must always fight. God is a fighter, even He Himself. God is a conqueror. He is a devouring lion. Nothingness hems Him in and He hurls it down. And the rhythm of the fight is the supreme harmony. Such harmony is not for thy mortal ears. It is enough for thee to know that it exists. Do thy duty in peace and leave the rest to the Gods."
