Hebrews 10:26-29

For if we deliberately go on sinning after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a terrifying expectation of judgment and the fury of a fire about to consume the adversaries. Anyone who disregarded the law of Moses died without mercy, based on the testimony of two or three witnesses. How much worse punishment do you think one will deserve who has trampled on the Son of God, who has regarded as profane the blood of the covenant by which he was sanctified, and who has insulted the Spirit of grace?
