Hebrews 10:35-39

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.
