In its context that verse refers to believers so it doesn't specifically say that all will be saved. At the most based on that verse, it states that those former believers will be saved yet so as though fire which I believe refers to the lake of fire. I think all will be saved has to be derived from the other verses in Scripture.
If even "former believers" are to be saved, & these are the worst sinners (cf. Heb.6:4-6; 10:26-29), how could it be that all other lessor sinners would not also be saved?
If the timoria punishment (Heb.10) is worse than the kolasis punishment (Mt.25), then shouldn't both be saved if the former shall be saved?
If even sinning unsaved ex-believers are, according to 1 Cor.3:15, to be saved postmortem after they are cast into the LOF, does that include those such as 1 Tim.1:19-20 refers to, who have been given over to Satan to be corrected in this life? Such had built upon the foundation of Christ referred to in 1 Cor. 3.
Does 1 Cor.3:15 include the immoral such as those in 1 Cor.5:4-5, who was also given over to Satan for the purpose of salvation? Or those referred to in:
Gal.5:4 You have been severed from Christ, you who are seeking to be justified by law; you have fallen from grace."
1 Tim. 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
Heb. 3:6 But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.
Heb. 12:15 Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble [you], and thereby many be defiled;
1 Cor. 9:27 But I keep under my body, and bring [it] into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
2 Pet. 2:20 If indeed they have escaped the corruption of the world through their knowledge of the Lord and Savior Jesus Christ, only to be entangled and overcome by it again, their final condition is worse than it was at first. 21 It would have been better for them not to have known the way of righteousness than to have known it and turned away from the holy commandment passed on to them.…
Ezek. 33:13
If I tell the righteous man that he will surely live, but he then trusts in his righteousness and commits iniquity, then none of his righteous works will be remembered; he will die because of the iniquity he has committed.
Col.1:21 Once you were alienated from God and were hostile in your minds because of your evil deeds. 22 But now He has reconciled you by Christ’s physical body through death to present you holy, unblemished, and blameless in His presence — 23 if indeed you continue in your faith,...
Lk.8:13 The seeds on rocky ground are those who hear the word and receive it with joy, but they have no root. They believe for a season, but in the time of testing, they fall away.
