Can a Christian lose their salvation?

Few questions create more anxiety for believers than the New Testament warnings about apostasy. Some Christians hold fast to the slogan once saved, always saved—as if the moment you trust in Jesus your future is forever sealed. Others replace eternal security with conditional security—the belief that while salvation is by grace alone through faith alone, that faith can be fragile, and the door is still open for Christians to walk away from Christ, shipwreck their faith, or fall from grace.

Now what makes this question so personal is that if you’ve been a Christian for any length of time, you’ll know people, perhaps even close friends, who once seemed on fire for Jesus, but who now want nothing to do with him. And we’re left asking: what happened? Sometimes even watching high-profile pastors or performers depart the faith raises a doubt within ourselves: are we really safe in God’s hands, or could we too blow it, and be cast aside?

Over the years of doing public ministry, I’ve met hundreds of Christians—especially younger ones—who are paralysed by this fear. They worry that because their experience of God has grown cold, or they have stumbled into some besetting sin, that this might just be evidence that they have either lost their salvation, or that they never truly believed.

So in this video, I want to wrestle with what Scripture teaches. First, I’ll map out the two dominant answers Christians give as a way traversing the biblical terrain. Next, I’ll explain why I think Christians are so divided on this question, and why that might be an intentional design feature. Finally, I’ll close with a pastoral reflection on how to ease some of the unnecessary dimensions of fear. So if you’re watching, stick around to the end. I genuinely hope it helps you.

But let’s start with the two major views:

First up, conditional security. This is the belief that Christians can, in fact, lose their salvation. And there’s no denying that the New Testament contains sobering warnings that lean in this direction.

Jesus warns in Matthew 7 that many who call him Lord—even those who perform miracles and cast out demons in his name—will still be rejected (Matthew 7:22-23). Given what happens in Acts 19 with the seven sons of Sceva, where the demons literally beat them up for trying to invoke Jesus’ name without his authority, it’s hard to think Jesus was talking only about fake believers in His Sermon on the Mount.

Then there’s Revelation 3, where Jesus threatens to spew out the lukewarm Christians in Laodicea (Revelation 3:16), and promises the believers in Sardis that only those who overcome will avoid having their names blotted out of the book of life (Revelation 3:5); a warning that suggests it is possible your name could be blotted out.

Paul also speaks of the necessity of perseverance. In 1 Corinthians 9:27 he disciplines his body lest he be “disqualified.” In Galatians 5:4 he warns some have “fallen from grace.” In Colossians 1:21–23 reconciliation is conditional: “if you continue in your faith.” These warnings only carry serious force if falling away were possible.

Then comes Hebrews 6:4–6, perhaps the strongest text on apostasy: “It is impossible for those who have once been enlightened… who have shared in the Holy Spirit… and then fallen away, to be brought back to repentance.”

Now if you just read that at face value, it seems to say that people who’ve truly shared in the Spirit—A.K.A. real believers—can still fall away, leaving them in a state of apostasy that is beyond spiritual renewal. That’s a terrifying prospect. And it’s not the only warning in Hebrews. Chapter 10 says that if we deliberately keep on sinning after receiving the truth, no sacrifice for sins remains; only the fearful prospect of judgment (Hebrews 10:26-27).

Together these passages form the case for conditional security.

On the other side of the debate is a second option: eternal security. This is the belief that real Christians, those truly born again, will never fall away. And the New Testament is rich with that assurance.

Jesus says in John 10, “My sheep hear my voice; I know them, and they follow me. I give them eternal life, and they shall never perish. No one can snatch them out of my hand” (John 10:27-28). And in John 6, He promises He will lose none the Father gives Him (John 6:39-40).

In one of the most soaring passages in Scripture, Romans 8, Paul lays out the golden chain of salvation—linking God’s foreknowledge of Christians to their predestination, calling, justification, and glorification (Romans 8:29-30). In other words, what God starts, God finishes; a sentiment Paul says explicitly in Philippians 1:6. And with these unbroken links stretching from eternity past to eternity future, it’s hard not to read Romans 8 as a full-throated declaration of eternal security, an assurance prompting Paul’s to exclaim that nothing in all creation can separate Christians from the love of Christ (Romans 8:28).

Then in Ephesians 1, Paul writes believers are “sealed with the Holy Spirit,” a deposit guaranteeing our inheritance (Ephesians 1:14). For a Christian to lose salvation, God would have to revoke His own seal, withdraw His Spirit, and cancel His gift—yet Paul insists, “the gifts and call of God are irrevocable” (Romans 11:29).

And salvation doesn’t just change our status—it changes our nature. Paul writes to the Christians in Corinth, “If anyone is in Christ, he is a new creation; the old has gone, the new has come” (2 Corinthians 5:17). For a Christian to be lost, that new creation God would later have to uncreate.

So proponents of eternal security lean into the divine origins of salvation, arguing that if Christians could lose their salvation, they would, but that our gospel assurance rests on God’s secure grip.

But here’s the catch: neither position fully relieves our fears. If you believe in conditional security, you live with the anxiety that you might fall away. If you believe in eternal security, you still wonder whether you were ever truly saved. Either way, anxiety remains.

But what if that tension is intentional? What if Scripture’s purpose is not, like math, simply to balance a theological equation? What if Scripture is more like chemistry, divinely inspired to produce a spiritual reaction?

If God’s endgame is, as Revelation teaches, to forge us into the gardeners and governors of the new creation—wise, humble, and holy—then Scripture functions as His spiritual curriculum.

To the proud or rebellious who presume upon grace, God speaks warnings of judgment—to shake them awake. Strong warnings are meant to create soft hearts. But to the broken, the fearful, the self-doubting, God whispers promises of security—to steady their trembling faith.

Scripture we are told is living and active, sharper than a double edged sword, designed to cut to the heart, expose our true needs, and perform soul-saving surgery, preparing us for judgment (Hebrews 4:12).

So is it any wonder we can string passages together to make a case in both directions? Scripture is designed for action on the ground, being rightly applied pastorally to meet our situational needs.

And maybe that’s God’s point. Because both truths—warning and assurance—serve God’s greater purpose: to keep us close to Christ. To serve a guard rails that keep us from falling off the cliff of apostasy.

So maybe the better question isn’t can a Christian lose salvation? But how can I know that I’m saved?

John writes, “I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life” (1 John 5:13). And notice in John’s first epistle, assurance of salvation is rooted in faith in Jesus, and in the fruit that grows out of true faith.

That’s why John’s letter gives several tests of saving faith: The doctrinal test: confessing the true Jesus. The social test: loving your brothers and sisters. The spiritual test: the Spirit’s inner witness. The moral test: walking in the light with a tender conscience.

These are not hoops to earn salvation, but evidences your salvation is real. So here’s my answer—both theological and pastoral: Can a Christian lose their salvation? No—but don’t.

I do not believe God will uncreate a new creation, nor condemn one He’s already justified, nor cancel the Spirit’s deposit. But God only feeds those who are spiritually hungry with such theological assurance, while to those who have fallen asleep at the wheel spiritually, his warnings are a clarion call to wake up, and turn back to Christ, lest we fall of the cliff of apostasy.

So—Believe in Jesus.
Remain in Jesus.
Bear the fruit of saving faith.

That’s how you know you have eternal life.

And if you’re asking this question with a tender heart, worried you might miss eternity with Jesus—take heart. That very sensitivity, that sorrow over sin and love for Christ, is evidence His Spirit is already at work in you.
