Heb. 10:19. Therefore, brethren, since we have confidence to enter the holy place by the blood of Jesus,
20. by a new and living way which He inaugurated for us through the veil, that is, His flesh,
21. and since we have a great priest over the house of God,
22. let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
23. Let us hold fast the confession of our hope without wavering, for He who promised is faithful;
24. and let us consider how to stimulate one another to love and good deeds,
25. not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the more as you see the day drawing near.
26. For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins,
27. but a terrifying expectation of judgment and THE FURY OF A FIRE WHICH WILL CONSUME THE ADVERSARIES.
28. Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses.
29. How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
30. For we know Him who said, "VENGEANCE IS MINE, I WILL REPAY." And again, "THE LORD WILL JUDGE HIS PEOPLE."
31. It is a terrifying thing to fall into the hands of the living God.
32. But remember the former days, when, after being enlightened, you endured a great conflict of sufferings,
33. partly by being made a public spectacle through reproaches and tribulations, and partly by becoming sharers with those who were so treated.
34. For you showed sympathy to the prisoners and accepted joyfully the seizure of your property, knowing that you have for yourselves a better possession and a lasting one.
35. Therefore, do not throw away your confidence, which has a great reward.
36. For you have need of endurance, so that when you have done the will of God, you may receive what was promised.
37. FOR YET IN A VERY LITTLE WHILE, HE WHO IS COMING WILL COME, AND WILL NOT DELAY.
38. BUT MY RIGHTEOUS ONE SHALL LIVE BY FAITH; AND IF HE SHRINKS BACK, MY SOUL HAS NO PLEASURE IN HIM.
39. But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul.
Verses 19-25 eliminate any possibility whatsoever that this passage is written to Jews who were not Christians; and the only sacrifice mentioned in this passage is the sacrifice on the cross, the shedding of the blood of Jesus for our sin (vv. 19 & 29). Verses 28-29 contrast the fate of Jews who sinned under the Law of Moses with the fate of Christians who sin, thereby effectively regarding as unclean the blood of the covenant (New Testament covenant) by which they were sanctified. Compare:
1 Cor. 6:9. Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals,
10. nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God.
11. Such were some of you; but you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus Christ and in the Spirit of our God.
Hebrews 10:19-39 is a warning to Christians of the danger of willful sin. My dear Christian readers, if you are still entangled in the bonds of sin, you must place your faith in the redemptive work of Christ on the cross and in His promise to each of us,
John 8:31. So Jesus was saying to those Jews who had believed Him, If you continue in My word, then you are truly disciples of Mine;
32. and you will know the truth, and the truth will make you free.
33. They answered Him, We are Abraham's descendants and have never yet been enslaved to anyone; how is it that You say, You will become free?
34. Jesus answered them, Truly, truly, I say to you, everyone who commits sin is the slave of sin.
35. The slave does not remain in the house forever; the son does remain forever.
36. So if the Son makes you free, you will be free indeed.
