Hebrews 10:26-27

10:26 For if we deliberately keep on sinning after receiving the knowledge of the truth, no further sacrifice for sins is left for us, 10:27 but only a certain fearful expectation of judgment and a fury of fire that will consume God’s enemies.

Hebrews 10:29

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?
