Also if one keeps on sinning the blood of Christ does not save them.
26For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,27But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.28He that despised Moses' law died without mercy under two or three witnesses:29 Of how much sorer punishment, suppose ye , shall he be thought worthy , who hath trodden under foot the Son of God,
and hath counted the blood of the covenant, wherewith he was sanctified , an unholy thing, and hath done despite unto the Spirit of grace?30For we know him that hath said , Vengeance belongeth unto me, I will recompense , saith the Lord.
Heb. 10:26-30
So if one keeps sinning God says they have counted the blood of Christ as unholy. It will not save them but rather will stand against them in judgment.
