Hebrews 10:35-39

Therefore, do not throw away your confidence, which has a great reward. For you have need of endurance, so that when you have done the will of God, you may receive what was promised. FOR YET IN A VERY LITTLE WHILE, HE WHO IS COMING WILL COME, AND WILL NOT DELAY. BUT MY RIGHTEOUS ONE SHALL LIVE BY FAITH; AND IF HE SHRINKS BACK, MY SOUL HAS NO PLEASURE IN HIM. But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul.
