Regarding the issue of whether salvation is a gift that can received and then lost, it is self evident that the grace of salvation would be pointless, useless, and actually meaningless if it is eventually lost. To put it another way, if the gift of salvation is only a temporary gift, and it isn’t accompanied by the gift (grace) of perseverance, then it has no point and no purpose.
On this point I disagree respectfully. A gift is a gift because it is given without compulsion or exchange. Grace is free because we have not earned it, and it remains a gift whether or not we accept it. Neither does it lose its meaning, as a gift retains its meaning even if it does not accomplish what is intended.
Indeed, Grace can be frustrated. Paul urges the Corinthians to reconciliation so that the Grace they received shall not be wasted:
2 Cor 5:20 - 6:1
“Therefore, we are ambassadors for Christ, as though God were making an appeal through us; we beg you on behalf of Christ, be reconciled to God. He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him. And working together with Him, we also urge you not to receive the grace of God in vain.”
Paul admonishes the Corinthians to reconciliation, after making note that they stand firm in faith (1:24). If they have faith, they have it by Grace, and if that Grace is imperishable, there is no need to fear it being lost. Yet Paul precisely argues this and gives as his reason his fear that the Grace will be in vain. Likewise he writes in 1 Cor 15:10 and Philemon 2:16 of Grace not being in vain.
Likewise, he writes of those who have forsaken this Grace in Hebrews 6:4-6
“For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, and then have fallen away, it is impossible to renew them again to repentance, since they again crucify to themselves the Son of God and put Him to open shame.”
Paul writes not of false converts or those who had outward appearances of Grace but inwardly never received Grace. Without Grace, one cannot be enlightened, cannot receive the Holy Spirit (much less be a partaker of the Holy Spirit), cannot have ‘tasted of the heavenly gift’ unless that heavenly gift has been given. Strong words are fitting here because the forsaking of the gift is so terrible, yet it is possible. If one has fallen away because one never received the gift, such admonishments would be unnecessary.
Paul’s recourse to the temptation to fall away is in Heb 6:11-12:
“And we desire that each one of you show the same diligence so as to realize the full assurance of hope until the end, so that you will not be sluggish, but imitators of those who through faith and patience inherit the promises.”
Perseverence, in other words, is not merely a gift to be received but a response to be lived. It is a cooperation with the very Grace that God gives freely.
Note that the language of cooperation is not alien to Scripture:
Mark 16:20 “Then the disciples went out and preached everywhere, and the Lord worked with them and confirmed his word by the signs that accompanied it.”
Here, God cooperates with man to produce salvation - the goal of preaching. This is the same working together that we see in 2 Cor 6:1.
Now we’re getting to another of your objections, that of free will. I must admit I labored in vain

to find a passage specifically stating in favor of or against free will. I think it’s too modern of a term to find in Scripture, but where I found language that describes believers as slaves of Christ(Eph 6:6), I also found language that describes us as God’s fellow workers (1 Cor 3:9). Perhaps the Thomist perspective merits revisiting, but I don’t feel like delving into “City of God” at this late hour.
I’ll be less formal and conclude by noting that the language of Scripture is participative rather than definitive. Okay, that’s formal language - sorry. If we do not have participation in the Grace we receive - if it truly overrides our will and controls us - then we expect language describing good works as being derivative - ie, “You will know them by their fruits” or you will do these because of the Grace you have received.
We have this language, and we also have its opposite:
1 Tim 6:18 Command them to do good, to be rich in good deeds, and to be generous and willing to share.
Heb 3:16 And do not forget to do good and to share with others, for with such sacrifices God is pleased.
1 Th 3-4 It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control his own body in a way that is holy and honorable.
1 Th 5:22 Avoid every kind of evil.
Gal 6:10 Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers.
This is language of participation, not merely derivation. Scripture attests both that Christ is our Savior and salvation is impossible without Him, and also that we are active participants in our salvation. These ideas are not contradictory nor mutually exclusive.
Perhaps this thread would benefit from some time to pray and think. I’ve been praying on our discussions here and I thank you all for offering them. May the Lord preserve you and grant you the Grace the sustain you, especially in the week that comes.
