ONLY a born again person has an epignosis of Christ. BOTH Heb. 10:26-27
Heb 10 is using figurative language to give encouragement to the believer.
Heb 3:13
But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin's deceitfulness.
Heb 10:25 not giving up meeting together, as some are in the habit of doing,
but encouraging one another—and all the more as you see the Day approaching.
Heb 12:5
And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says, “My son, do not make light of the Lord's discipline, and do not lose heart when he rebukes you,
=================================================
Hearing and not receiving represents nonbelievers, but those in Heb 10 received the knowledge.
I do believe Heb 10:19-39 is referring to believers in Christ, but it is in fact using figurative language like all the warnings in Hebrews.
Heb 6:4-6 and Heb 10:19-39 are both referring to maturity in Christ, they simply worded it in a different way (Heb 6:6 and Heb 10:26 hold to the same language of crucifixion).
I had stated a while back that Heb 6:4-6 is referring to maturity in Christ, thus starting at Heb 5:11. Can that not be applied to Heb 10 also? If it wasn't figurative then God would be changing His mind of eternal security in one verse to the next. In this case one section to the next, Heb 10:1-18 vs Heb 10:19-39.
Another way to look at the warnings in Hebrews is that the author is encouraging us by using figurative language to run the race and fight the good fight. The religious see the warnings as literal, but true believers see it as encouragement.
Do believers not have a word of encouragement when we're disciplined, Heb 12:5-6.
Heb 10:19
Therefore, brothers and sisters, since we have confidence to enter the Most Holy Place by the blood of Jesus,
1 Jhn 5:14
This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us.
