Hebrews 10:29-31
10:29 How much greater punishment do you think that person deserves who has contempt for the Son of God, and profanes the blood of the covenant that made him holy, and insults the Spirit of grace?
10:30 For we know the one who said, “Vengeance is mine, I will repay,” and again, “The Lord will judge his people.”
10:31 It is a terrifying thing to fall into the hands of the living God.
