Endurance is not just the ability to bear a hard thing, but to turn it to glory.—William Barclay (1907–1978)

We must persevere in prayer that He may not permit our hearts to faint. Prayer and perseverance are necessary in our daily conflicts. The best remedy to the weariness is diligence in prayer.—John Calvin (1509–1564)

All the performances of human art, at which we look with praise or wonder, are instances of the resistless force of perseverance: it is by this that the quarry becomes a pyramid, and that distant countries are united with canals. If a man was to compare the effect of a single stroke of the pickaxe, or of one impression of the spade, with the general design and last result, he would be overwhelmed by the sense of their disproportion; yet those petty operations, incessantly continued, in time surmount the greatest difficulties, and mountains are levelled, and oceans bounded, by the slender force of human beings.—Samuel Johnson (1709–1784)

Though today may not fulfill
All your hopes, have patience still;
For perchance tomorrow’s sun
Sees your happier days begun.

Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.—John Quincy Adams (1767–1848)

Never stop fighting until you arrive at your destined place—that is, the unique you. Have an aim in life, continuously acquire knowledge, work hard, and have perseverance.—A. P. J. Abdul Kalam (1931–2015)

Success is no accident. It is hard work, perseverance, learning, studying, sacrifice and most of all, love of what you are doing or learning to do.—Pelé (b. 1940)

Courage is not having the strength to go on; it is going on when you don’t have the strength.―Theodore Roosevelt (1858–1919)

Don’t ever give up. Don’t ever give in. Don’t ever stop trying. Don’t ever sell out. And if you find yourself succumbing to one of the above for a brief moment, pick yourself up, brush yourself off, whisper a prayer, and start where you left off. But never, ever, ever give up.—Richelle E. Goodrich, Eena, The Tempter’s Snare (2014)

When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.—Helen Keller (1880–1968)

Let us not grow weary of doing good, for in due season we will reap, if we do not give up.—Galatians 6:9 ESV
