Hebrews 10

36. For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.
37. For yet a little while, and he that shall come will come, and will not tarry.
38. Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.
39. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
