I will throw you to the lions.
Here is what the reverend Chat GPT has to say.
Is endurance in that faith in Jesus necessary or can we fall into unbelief and still be saved? Please use only the New Testament.

That’s a profound and crucial question—one that the New Testament takes very seriously. Let's explore it honestly and clearly using only New Testament passages.
1. Faith is the Means of Salvation
We start here because the New Testament is clear:
"For by grace you have been saved through faith."
— Ephesians 2:8
"Whoever believes in him shall not perish but have eternal life."
— John 3:16
So faith is the
means by which we receive grace. But the question you're raising is
what if we stop believing—what then?
2. Endurance Is Repeatedly Commanded
The New Testament strongly emphasizes
continuing in the faith—not just starting in it.
"But the one who endures to the end will be saved."
— Matthew 24:13
"We have come to share in Christ, if indeed we hold our original confidence firm to the end."
— Hebrews 3:14
This implies a conditional relationship: sharing in Christ
depends on continuing in faith, not abandoning it.
3. Warnings Against Falling Away
Hebrews especially issues strong warnings:
"Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God."
— Hebrews 3:12
"For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins."
— Hebrews 10:26
"It is impossible... if they fall away, to be brought back to repentance..."
— Hebrews 6:4–6
These are sobering verses that indicate the real danger of falling into unbelief after once believing.
4. Faith Must Be Maintained
Paul uses language like:
"I have fought the good fight, I have finished the race, I have kept the faith."
— 2 Timothy 4:7
And instructs:
"Continue in the faith, stable and steadfast, not shifting from the hope of the gospel."
— Colossians 1:23
If salvation were secure regardless of faith, there would be no need to warn believers to "keep the faith."
5. Examples of Shipwrecked Faith
Paul mentions individuals who once believed but departed:
"By rejecting this, some have made shipwreck of their faith, among whom are Hymenaeus and Alexander."
— 1 Timothy 1:19–20
He even says:
"Demas, having loved this present world, has deserted me."
— 2 Timothy 4:10
These are not unbelievers from the start—they departed from something they once held.
6. But What About God's Faithfulness?
Yes, God is faithful—but His faithfulness doesn't override human will:
"If we endure, we will also reign with him; if we deny him, he also will deny us."
— 2 Timothy 2:12
"If we are faithless, he remains faithful—for he cannot deny himself."
— 2 Timothy 2:13
This last verse is sometimes taken to mean God saves us even if we stop believing, but in context, it more likely means
He remains faithful to His word, including His promises
and His warnings.
7. Summary
According to the New Testament:
- Faith saves — always and only by grace.
- But faith must endure—because…
- A believer can fall away through unbelief.
- Those who endure to the end will be saved.
So to your question—
can we fall into unbelief and still be saved?—the New Testament seems to say
no. Salvation is never earned, but faith is the living connection to Christ. Without it, we are cut off.
