The fact that the Christian didn't know in the same book of Hebrews, but Chaper 10 verse 26 lets him know
For if we sin willfully after we have received the knowledge of the truth,
there no longer remains a sacrifice for sins.

1 John 3:4
4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law
So the israelite brothers was right. If you are in sin (willfully) then the blood of Christ takes no effect. But the goofy Christian didn't know all this. He think just because Christ died for him, he can do whatever he want and the blood of Jesus will cover him

He should have shut up and listened to the brothers. Or the brothers need to let a elder grab the loudspeaker and teach if they not up on their bible verses
