“Ah, my brother, it is a far harder thing, and it is afar higher proof of a thorough-going, persistent, Christian principle woven into the very texture of my soul, to go on plodding and patient, never taken by surprise by any small temptation, than to gather into myself the strength which God has given me, and, expecting some great storm to come down upon me, to stand fast, and let it rage. It is a great deal easier to die once for Christ than to live always for Him.”

Letter X
The Nemesis of Faith (1849)
Context: To suppose that by our disobedience we have taken something away from God, in the loss of which He suffers, for which He requires satisfaction, and that this satisfaction has been made to Him by the cross sacrifice (as if doing wrong were incurring a debt to Him, which somehow must be paid, though it matters not by whom), is so infinitely derogatory to His majesty, to every idea which I can form of His nature, that to believe it in any such sense as this confounds and overwhelms me. In the strength of my own soul, for myself, at least, I would say boldly, rather let me bear the consequences of my own acts myself, even if it be eternal vengeance, and God requires it, than allow the shadow of my sin to fall upon the innocent.

Quoted in The Rebellious Life of Mrs. Rosa Parks, by Jeanne Theoharis (2013)

Je te le déclare, en mon âme et conscience, la conquête du pouvoir ou d'une grande renommée littéraire me paraissait un triomphe moins difficile à obtenir qu'un succès auprès d'une femme de haut rang, jeune, spirituelle et gracieuse.

The Odyssey : A Modern Sequel (1938)
Context: A slave's soul has no worth, my brothers; it lacks strength
to tread on this great earth with gallantry and freedom.
I pity the poor slaves, they're nought but airy mist,
a light breeze scatters them, a fragrance knocks them down;
it's only just they crawl on the earth on hands and knees.
Today I'll write a hymn to God and pray for this great grace.
