Hebrews 10:19 the same Hebrews the author is addressing in verse 26. Verse 26 is a hypothetical situation.
A single verse in the blble can be talking both literally and prophetically.
The verses in the bible are "spirit and they are truth".
They are not just words.
So, this is why we find John talking to unbelievers in 1 John 1:9, then in the 2nd Chapter he's talking to the believers, and again in chapter 3.
This is why God tells us to "rightly divide" to "show ourselves approved".
Approved as what?
Approved so as not be found as teaching heresy.
For example, Paul tells the carnal church at Corinth to discipline a young man who is having sexual relations with his Dad's new wife.
So, thats willful sinning by a born again Christian.
Does Paul say...>"you have sinned willfully, and now you are going to hell".
Of course not., as The young man is born again, but is committing fornication as a born again Christian.
This is not very unique.
So, the Corinth church sends the young man on a sabbatical to let him think about it and get that worked out.
Then later Paul says.. (paraphrase)...>"well, we dont want him to be overcome with grief, to the point of doing something drastic."" ........So they let him back in the Church, and Paul told them to do it.
It does not say if the woman was allowed back in, but as she was not even mentioned later, we could assume that she's not born again, so in that case, Paul would not have anything to say about her.
Now, when we look at the Christ rejecting Hebrews, in Chapter 10 and Acts 28, you do not find Paul allowing them another chance to make a wrong a right. So, by this, we see that they were not
born again, and that is why Paul warns them so intensely.
He is telling them.. (Paraphrase)......"If you reject your messiah, you are going to burn in the lake of fire with your Daddy the Devil".
And they will not hear.
You also read this...>"they tasted the heavenly GIFT"., and this verse trips up most believers who dont even read their bible, much less study it
See that """" Heavenly GIFT"""?
That is not them receiving the Holy Spirit..... That is these JEWS, who "require a SIGN" as "signs are for the JEWS">........seeing Paul perform 2nd Corinthians 12:12 before their very Eyes.
He performed the "signs of an Aposlle", or a """"Heavenly Gift""", as all the SIGNS are Heavenly GIFTS, and the Apostles had unique ones that regular Christians dont Possess.
For example, Paul once caused a male Witch to go BLIND.
See that? That is the power of an APOSTLE, in that DAY.
And these Jews, in Hebrews 10, tasted this heavenly GIFT, that Paul had...>He showed them Power from HEAVEN, and they still would not receive Christ as their Messiah.
This is why Paul told them that there "remains no more sacrifice"....as there isn't any, if you reject the Sacrifice, who is JESUS.
THEY DID.
And they did it again, in Acts 28.
