show me where in 1 Corinthians 15 it says you CAN'T lose your salvation
Guess what Paul doesn't say in 1 Cor 15? "You CAN'T lose your salvation".
Guess what else Paul doesn't say in 1 Cor 15? You CAN lose your salvation"
Boy, wouldn't it be nice if he'd said one or the other? But we can deduce his logic on this matter. Here's how:
1 Corinthians 15:10-11, 22-23, 28, 57
But by the grace of God I am what I am, and his grace to me has not been in vain,
But by.... I.e. It's God's Grace alone. Yes I know you say you've recognized that a person cannot initially become saved
but by God's Grace in conjunction with their free-will choice. Cool, I agree. How about maintaining it? I even agree one must maintain their free-will choice. I recognize, however, we have a Helper to do that very thing. Frankly, you've not addressed any of the passages that help to deduce OSAS?'s answer relative to the sealing and helping value of the H.S. Jesus didn't leave us without the 3rd person. He did so for a reason. But to stay close to the 1 Cor 15:1_-2 passage's evidence:
Your idea of what Paul meant to say in verse 1-2, (they are warned to not let their initial saving belief become 'vain' in the future) conflicts not only with the verse itself, but with verse 10-11 if you think it thru. Plus it requires a metaphorical meaning to the word "vain".
his grace to me has not been in vain,
A person simply cannot make God's grace that has truly been imparted to them by none other than God Himself become vain.
Which is why "unless they believed in vain" (past tense) means what it says. There were people there that had believed in vain, past tense. That's what the verse says. Not might have or might in the future, but did already. God's Grace is not vain now or in the future, their belief was, is the point.
but I labored even more than all of them, and not I, but the grace of God with me.
I feel that God accomplishes what He set's out to accomplish, 100% of the time. I believe I can support that claim Biblically. It makes zero sense to me for God to labor along with a believer toward their salvation, knowing full well the end result will be vain. But the point here is that for your view to be accurate about verse 1-2, not only would their labor be 'vain' but God's grace would be also. That doesn't make sense.
and in this way you believed.
And the point is, that these things don't just apply to Paul, but to us non-vain believers too.
For just as in Adam all die, so also in Christ all will be made alive.
All, not some, WILL BE. Yes, I know that means all that are
in Christ and your claim is people can leave Christ. But we are told elsewhere that Christ rejects the one's He NEVER knew. Not the one's He once knew. So there's a conflict on your view with what Paul says here.
But each in his own group: Christ the first fruits, then those who are Christ’s at his coming,
All 100% of His sheep, not just 99%. Or for that matter, special groups. Even the one that wanders away. Paul, not me, seems to be making the point that all groups AND the individual believers within them belong to Christ.
But whenever all things are subjected to him, then the Son himself will be subjected to the one who subjected all things to him, in order that God may be all in all.
God is in All things!! Not just some things. Is God in a failed Christian? No, in my opinion. God is always victorious.
But thanks be to God, who gives us the victory through our Lord Jesus Christ!
God gives victory, not a potential for victory.
