Hebrews 9:28

So Christ was once offered to bear the sins of (s) many; (16) and unto them that look for him shall he appear the second time without sin unto salvation.

(s) Thus the general promise is restrained to the elect only: and we have to seek the testimony of our election, not in the secret counsel of God, but in the effects that our faith works, and so we must climb up from the lowest step to the highest, there to find such comfort as is most certain, and shall never be moved.

(16) Shortly by the way he sets Christ as Judge, partly to terrify those who are not trusting in the only sacrifice of Christ once made, and partly to keep the faithful in their duty, so that they will not go back.
