Hebrews 9:23-28

It was necessary therefore that the copies of the things in the heavens should be cleansed with these; but the heavenly things themselves with better sacrifices than these. For Christ entered not into a holy place made with hands, like in pattern to the true; but into heaven itself, now to appear before the face of God for us: nor yet that he should offer himself often, as the high priest entereth into the holy place year by year with blood not his own; else must he often have suffered since the foundation of the world: but now once at the end of the ages hath he been manifested to put away sin by the sacrifice of himself. And inasmuch as it is appointed unto men once to die, and after this cometh judgment; so Christ also, having been once offered to bear the sins of many, shall appear a second time, apart from sin, to them that wait for him, unto salvation.
