Doug Brents replied [post #1252], "Just FYI, Heb 10:10 says “once for all”, not ‘once and for all’.
“Once for all” means that Christ died once, and His sacrifice was for all (unlike the repetitive sacrifices of the Old Covenant).
This is not the common saying “once and for all” implying “finally” or “at long last” (which is true, but not the implication of this verse."
My Reply :
Yes, I would agree with your statement that Christ's sacrifice was "once for all" in the sense that it was unlike [and vastly superior to] the repetitive sacrifices of the Old Covenant; however, I would disagree with you as it pertains to the implications of a believer's eternal security. The critical verse that adds more substance to that discussion is found in verse 14.
Hebrews 10:14, "For by one offering he hath perfected for ever them that are sanctified." [KJV].
Hebrews 10 :14 - Greek interlinear :
"By one [mia] for [gar] offering [prosphora] He has perfected [teteleiōken] for all time [eis to diēnekes] those [tous] being sanctified [hagiazomenous]."

Where should the emphasis be placed?
Generally speaking, those of the LOS [Loss Of Salvation] camp emphasize the aspect of the singularity of Christ's sacrifice [i.e. - it's completeness and sufficiency for the forgiveness and redemption of humanity throughout all of history] ... "For by one offering." That is, Christ had offered for all time a single sacrifice for sins [forever abolishing the need of it's repetition, as well as the Old Covenant sacrificial system]. It was Christ's singular act of atonement that provided a perfect and acceptable sacrifice which alone could satisfy God's holy righteousness and justice].
On the other hand, the opposing camp, the OJAS ["Once Justified, Always Justified"] or OASAAS ["Once Actually Saved, Always Actually Saved"] advocates by and large focus upon the resulting effect of Christ's singular sacrifice upon those who have placed their faith in it's efficacy and sufficiency to obtain their right-standing before God ... "he hath perfected for ever [for all time] them that are sanctified [those being sanctified]." To state it in a slightly different manner for further clarity ... "those being sanctified" - all those who, from age to age, through faith receive as their own that which has been procured for all men.
Although it is true that we do not have an "either/or", but rather a "both/and" scenario in view here [each camp representing one-half of the dual truths declared in Hebrews 10:14], it appears to me that there is compelling evidence contained within this verse supporting the OJAJ position.
Should we view the sanctification spoken of here ["those being sanctified"] in a positional or progressive sense?
Although it certainly looks to me that positional sanctification is in view here, a person's perspective on this issue actually matters little as it pertains to the question of the eternal security of the believer [as I will attempt to demonstrate by the following truth claims].
(1) A person cannot be progressively sanctified unless he/she has been positionally sanctified [or set apart by God as holy].
(2) A person cannot be sanctified in either a positional or progressive sense without also experiencing a justified status before God. [1 Corinthians 6:11].
(3) All those who have been justified will also be glorified [in both it's "already" and "not yet" dimensions]. Although glorification is viewed as including a present [continous] sanctifying/transformational work of the Holy Spirit operating in the lives of believers, there is also a future aspect attached to it ... the reception of a glorified body - a resurrection body in Heaven.
Therefore, positional and progressive sanctification, as well as the [ultimate] redemption of the body, are states that will be actualized in all of those ["from age to age"] who experience a justified status before God.
Romans 6:5 [Greek Interlinear] - "If [Ei] for [gar] united [symphytoi] we have become [gegonamen] in the [tō] likeness [homoiōmati] of the [tou] death [thanatou] of Him [autou] certainly [alla] also [kai] of the [tēs] resurrection [anastaseōs] we will be [esometha]."
Romans 6:5 [English Standard Version] - "For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his."... it certainly [alla] sounds to me that both OJAJ [Once Justified, Always Justified] and OASAAS [Once Actually Saved, Always Actually Saved] are truths proclaimed by the scriptures .... it doesn't get any better than this my friends!!! ... All Praise and Glory to Jesus Christ! - The [Singular] Precious Lamb of God!!!
