Hebrews 10:36-39

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