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 is promised. For, “Yet a little while, and the coming one 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 and are destroyed, but of those who have faith and preserve their souls.
