Which goes along with,
And because ye are sons [Paul's audience], God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. (Galatians 4:6)
Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again [those who were set free] with the yoke of bondage [going back into what they were set free from]. Behold, I Paul say unto you, that if [submission to Judaizers these believers are being warned against] ye be circumcised [signifying justification obtained by keeping all the law], Christ shall profit you nothing. For I testify again to every man that is circumcised, that he is a debtor to do the whole law. Christ is become [an effectual change due to their choice] of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace[their former state]. For we [those who continue to believe] through the Spirit wait for the hope of righteousness by faith. (Galatians 5:1-5)
Take heed, brethren, [contextually not a general sense, but as believers] lest there be in any of you an evil heart of unbelief, in departing from the living God [a departure from their former state s believers]. But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin [a change of heart]. For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end [[perseverance of the saints]. (Hebrews 3:12-14)
Let us hold fast the profession of our faith without wavering [continued exhortation to persevere]; (for he is faithful that promised
And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, [indicating departing from the faith, as follows] as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. (Hebrews 10:23-25)
For if [a choice brethren are warned against] we [not just you] sin wilfully [not out of weakness, but with full consent, as a decision not to continue but to depart, signified by giving up being with the believers] after that we have received the knowledge of the truth [a term which refers to believing, as per 1Tim. 2:4; 2Tim. 3:7], there remaineth no more sacrifice for sins [cf. Hebrews 6:6-8; a terminal condition of judgment, with no provision for repentance and forgiveness, having forfeited what saving faith obtained], But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries. (Hebrews 10:26-27)
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 the blood of the covenant, wherewith he was sanctified [a past condition, appropriated by faith, now forfeited by a definite denial of the same] , an unholy thing, and hath done despite unto the Spirit of grace? (Hebrews 10:28-29)
Cast not away therefore your confidence, [the issue being faith, out of which obedience flows] 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 [not that doing earns the promise, but that saving faith is that which finally perseveres, which faith as manifested in works God - who gave faith and the ability and motivation to obey - rewards under grace] For yet a little while, and he that shall come will come, and will not tarry.
Now the just shall live by faith [the just live by faith, not merely profess it, with such faith being what appropriates justification]: but if any man draw back [a denial of justifying faith], my soul shall have no pleasure in him [as solemnly, fearfully described above]. But we [who do not draw back, but persevere] are not of them who draw back unto perdition [contextually a terminal condition of judgment, with no provision for repentance and forgiveness due to treating Christ with contempt] but of them that believe to the saving of the soul. (Hebrews 10:35-39)
Such departing from the the living God, drawing backing into perdition, falling from grace, etc., is likely the the "great transgression," (Psalms 9:13) that of having "wickedly departed from my God,"(2 Samuel 22:22) which David stated he did not do, despite his sins, for unlike apostates he overall kept the ways of the Lord, and confessed in repentance when convicted of not doing so, (2 Samuel 12:7-13)
It is the Father's will that none should perish and that all whom the Father gives Christ shall be saved, but as with Judas, there are some sons of perdition. Whatever glorifies God most should be what we want.
Note again that the above verses are clearly written to believers as believers, exhorting them to continue in the faith and warning against rejecting it, and thus these cannot be dismissed as never having been born again , although there are those who left fellowship since they were never in Christ. (1 John 2:19)
And again, salvation is by grace thru faith, however, salvation being by grace and not by works does not mean conversion takes place when one is comatose, but this is realized by a God enabled and motivated response.
for in conversion man does what he otherwise wold not and could not do. Man could not and would not believe on the Lord Jesus or follow Him unless God gave him life, and breath, and all good things he has, (Acts 17:25) and convicted him, (Jn. 16:8) drew him, (Jn. 6:44; 12:32) opened his heart, (Acts 16:14) and granted repentance (Acts 11:18) and gave faith, (Eph. 2:8,9) and then worked in him both to will and to do of His good pleasure the works He commands them to do. (Phil. 2:13; Eph. 2:10)
, Yet it is not be the merit of works that one is saved by, although works of faith as led by the Spirit are the credentials of faith. (Rm. 8:14; Heb. 6:9,10; 1 Thes. 1:7ff)
Therefore denying OSAS is not teaching salvation by grace thru faith and teaching salvation by the merit of works instead, since the issue is denying the faith, which is evidenced by works (thus such a sin as neglecting to take care one's own is said to to be denying the faith: 1 Tim. 5:8). Just as forgiveness and healing went together in the case of the palsied man in (Mark 2:2-11 so that the cause and the effect could be used interchangeably, so faith and works go together, yet it is heart-purifying faith (Acts 15:9) that is the effect, and is counted for righteousness, (Rm. 4:5) with acceptance in the Beloved (Eph. 1:6) being on His account, while works justify the believer as being a believer.
I once held to OSAS myself, and by nature would like to now, but in the light of Scripture I find it incontrovertible that believers are being addressed as believers in these texts, and I cannot see how all such can be dismissed as hypothetical, or that the consequences warned of are less than that of damnation as lost soul, and even of such being the more accountable.
Yet i pray and trust that as David said, The Lord will perfect that which concerneth me: thy mercy, O Lord, endureth for ever: forsake not the works of thine own hands. (Psalms 138:8)
Thanks be to God.
