The following is a Fact.
"Once for all" is ἐφάπαξ in the Greek. Strong's Lexicon in the back of his concordance concurs.
ἐφάπαξ
ephapax
ef-ap'-ax
From G1909 and G530; upon one occasion (only): - (at) once (for all).
UPON ONE OCCASION, only once. NOT TO BE REPEATED
.
By the which will we are sanctified through the offering of the body of Jesus Christ once for all (upon one occasion only, NOT TO BE REPEATED).
(Heb 10:10 KJV)
You can't prove it wrong. YOU KNOW WHY? Because it is grammatically and contextually true. GOD is very purposeful in HIS wording.
For by one offering he hath perfected for ever (not sanctified forever) them that are sanctified.
Two separate things. GOD has perfected for ever THEM THAT ARE sanctified.
This perfecting is the subject of the sentence. As the next sentence starts it starts with a word that brings what follows back to the subject. WHEREOF (back to the subject in the previous sentence, this perfection in which we speak) the Holy Ghost ALSO is a witness to us: for after that he had said before, This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them."
NOT SANCTIFIED forever, Sanctification can be lost as verses 26-29 put forth through God's Holy Spirit. But God's laws put in the heart and mind is forever.
For if WE (the church, including the writer) are sinning willfully after that we have received the knowledge of the truth (we are sanctified, a new wine skin filled with the New Wine, A new Conscience, the old purged and replaced with God's laws in the heart and mind through Christ's indwelling) there remaineth no more sacrifice for sins, But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries (those who are sinning willfully). He that despised Moses' law died without mercy under two or three witnesses: Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted (show by example, leading) the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? ( GOD'S Law in the hearts and minds)
(Heb 10:26-29)
WAS SANCTIFIED, Sanctification LOST because they done despite unto the Spirit of grace which they were given.
You can't do despite unto the Spirit unless you have the Spirit.
You can speculate that the writer is not including himself in the warning and that the sanctified are not truly sanctified but as for me and my house we will believe and follow the word of of GOD.
Wrong, these verses do not even come close to making that assertion.
Loss of sanctification not in view.. adding that to the text!!
Was sanctified means that they are not any more. If all they have a certain fearful looking forward to judgement and fiery indignation which SHALL DEVOUR THE ADVERSARY (the one sinning willfully that was sanctified) They shall be devoured. If they are devoured they are not anything anymore, including sanctified.
Now the just shall live by faith: but if he (
THE JUST ONE) draw back, my soul shall have no pleasure in him.
Where do they draw back to?
But we are not of them (
the just ones who are sinning willfully) who draw back unto destruction but of them that believe to the saving of the soul.
Verse 31 and 32 make it clear that the author of Hebrews is warning of temporal judgement not eternal.
31 It is a fearful thing to fall into the the hands of the living God."
32 But call to remembrance the former days, in which after ye were illuminated, ye endured a great flight of afflictions.
Not true.
Verse 31 is in context to what was previously stated. And verse 32 is exhortation to remember when they were persecuted by non believers. They become companions with them who so used, they were a gazing stock as they endured a great flight of afflictions. They were companions of them that were so used (
that also endured affliction and were a gazing stock). This includes the writer. We know that because right after that comment he starts his next sentence with the word "for" Which assigns a reason to what was previously stated. He says, "For they had compassion on the writer when he was in bonds and took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance."
But call to remembrance the former days , in which, after ye were illuminated (when they first came to knowledge of Christ) , ye endured a great fight of afflictions; Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used (
who were also a gazing stock due to the reproaches and afflictions).
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. Cast not away therefore your confidence, which hath great recompence of reward. For ye have need of patience, that, after ye have done the will of God, ye might receive the promise. For yet a little while, and he that shall come will come, and will not tarry. Now the just shall live by faith: but if he (the just one) draw back, my soul shall have no pleasure in him. But we are not of them (
the just ones) who draw back unto destruction; but of them that believe to the saving of the soul.
(Heb 10:32-39)
