I have been reading my Bible, let me see, if I remember correcly, about forty years. I think I know what the Bible says about salvation.
Sir, I was raised Southern Baptist. I’m 13, and my realization—that many Baptist notions concerning salvation are, in fact, unbiblical—was one of my first steps towards the Catholic Faith. If you don’t mind me throwing some verses at you, I think these might help:
“See, then, the kindness
and severity of God: severity toward those who fell, but God’s kindness to you, *provided *you remain in his kindness; otherwise you too will be cut off.” [Rom. 11:22]
This is perhaps the bluntest instance in Scripture where it is, in a word, said, “Persevere in his kindness, or perish.” For this reason, I placed it first.
“He has now reconciled in his fleshly body through his death, to present you holy, without blemish, and irreproachable before him,
provided that you persevere in the faith, firmly grounded, stable, and not shifting from the hope of the gospel that you heard.” [Col. 1:22-23]
The second verse demonstrates salvation is conditional.
“Those on rocky ground are the ones who, when they hear, receive the word with joy, but they have no root; *they believe only for a time and fall away *in time of trial.” [Lk. 8:13]
This passage attests to the fact that one can believe and fall away. We see it happen every day.
“If we sin deliberately after receiving knowledge of the truth,
there no longer remains sacrifice for sins but a fearful prospect of judgment and a flaming fire that is going to consume the adversaries.” [Heb. 10:26-27]
This one deals with mortal sins (intentional wrongdoing) after receiving the gospel: And the fate which awaits one who thusly transgresses the Almighty (for more on mortal sins, read 1 Jn 5).
“If they, having escaped the defilements of the world through the knowledge of (our) Lord and savior Jesus Christ, *again *become entangled and overcome by them, their last condition is worse than their first. For *it would have been better for them not to have known the way of righteousness than after knowing it to turn back from the holy commandment handed down to them. *What is expressed in the true proverb has happened to them, “The dog returns to its own vomit,” and "A bathed sow returns to wallowing in the mire.” [2 Pet. 2:20-22]
This Scripture reveals even after the regeneration of the Spirit through baptism, one can become “un-regenerated” again—a slave to sin once more.
“I drive my body and train it, for fear that, after having preached to others, *I myself should be disqualified.” *[1 Cor. 9:27]
Quite simple: Paul expresses concern regarding his eternal fate.
“I am not conscious of anything against me, but
I do not thereby stand acquitted; the one who judges me is the Lord.” [1 Cor. 4:4]
Paul admits the possibility of being unjustified in the sight of God, despite his conscience which may suggest otherwise.
I hope these help!
Peace and Truth in Christ
