Hebrews 10:35-38

So do not throw away your confidence; it will be richly rewarded. You need to persevere so that when you have done the will of God, you will receive what he has promised. For in just a very little while, "He who is coming will come and will not delay. But my righteous one will live by faith. And if he shrinks back, I will not be pleased with him."
Hebrews 10:35-38
