Only have a few minutes so I will give you something to consider in regards to this chapter, which I did in an earlier post (POST 17, Page One):
Hebrews 10:26-29
King James Version (KJV)
26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
28 He 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?
The reason there remains "no more sacrifice for sins" is pretty simple, if you are not indoctrinated into false doctrine...
...because they are rejecting the only thing that can save them.
In view are Hebrews, not Christians, and if you look at the text you will see that this is not contrasting good Christian/bad Christian...it is contrasting from among the Hebrew people those who rejected Moses' Law (the Covenant of Law) and those who reject, in order...
1. Jesus Christ, The Son of God;
2. His Sacrifice;
3. His Covenant;
4. The efforts of the Spirit of Grace, the Comforter, Who is the One Who convicts unbelievers of sin, righteousness, and judgment:
As mentioned earlier, most proof texts of the L.O.S.T. (loss of salvation teachers) improperly identify those being warned as regenerate believers. Here, it is a contrast between those who reject the Covenant of Law, and those who reject the New Covenant, which throughout the Book the Writer tries to convince his brethren (Hebrew) they must turn to Christ, rather than remain under Law.
If we continue in the text, which as mentioned before, has to be understood throughout (which I why I exhort you to understand the first half of the Chapter) in light of all that he writes, so we cannot make this contradict what he has already said:
30 For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.
31 It is a fearful thing to fall into the hands of the living God.
Who are the "People" in view? The same people in view in the original statement...Israel. In view is a judgment of God on the Hebrew people based on their response to His Word.
32 But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions;
33 Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used.
Again, spoken to Hebrews, and those associated with Christianity. The only thing we can say for sure is that they received illumination, which is what I was speaking of in regards to Hebrews 6:4-6. That is simply how men come to be saved, the Comforter ministers the Gospel to them, shows them the truth of the GOspel and the condition they lie in (lost and destined for Hell), and they respond. The response is not always saving faith. I myself was ministered to for well over a year, but probably closer to two.
34 For ye had compassion of me in my bonds, and took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance.
35 Cast not away therefore your confidence, which hath great recompence of reward.
36 For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.
37 For yet a little while, and he that shall come will come, and will not tarry.
38 Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.
39 But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
Verses 38-39 show the warning: do not draw back unto perdition. Same warning is found in Hebrews 6, "Emulate those who have faith."
What he does is distinguish between "drawing back unto perdition," and...believing to the saving of the soul. Only one of the two is actually saved.
But, again, until you understand this...
Hebrews 10:14
King James Version (KJV)
14 For by one offering he hath perfected for ever them that are sanctified.
...and see it for what it is, a clear statement of Eternal Security, you will have doubts about most of what you see in Hebrews, because we often look at our lives and wonder how God could save sinners like us. The fact is, it is because we could do nothing to save ourselves that He came to make Salvation a reality for us.
Again, just do me a favor, and spend some time in the first 14 verses of this chapter. And I almost gave you a hint, lol, but that would defeat the purpose. The statements made are pretty clear, and it is just a matter of keeping the context together.
And sorry, have to get going, so this has been rushed. And I didn't use the NIV, because I am not a fan of the newer one. The 1984 edition is not bad, but the newer one isn't so hot.
God bless.
