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.
Hebrews 10:35-39 NASB1995
Hebrews 10 is such an uplifting chapter to read! If I could sum up the whole chapter in one sentence, it would be:
Wholeheartedly trust in what Jesus did for you on the cross because His blood was enough to pay for all of your sins; past, present and future.
