Hebrews 10:26-29
“For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, … He that despised Moses' law died without mercy under two or three witnesses: Of how much sorer punishment, suppose you, shall he be thought worthy, who has trodden under foot the Son of God, and has counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and has done despite unto the Spirit of grace?”
