# You Can't Lose It, But You Might Never Have Had It
A man in our congregation — sharp, theologically literate, the kind who annotates his Bible in three colours — told me he'd stopped worrying about his sin because, as he put it, "the ticket's already punched." He said it cheerfully, the way you'd describe a flight you'd already checked in for. I didn't know whether to admire his confidence in grace or call his wife.
There was a moment, sitting opposite him in a coffee shop just off Old Street roundabout, when I genuinely couldn't tell which response was the more pastoral. He was right about something enormous. He was also, I suspected, wrong about something even larger. And the difference between those two things — between what he had grasped and what he had quietly skipped — is the difference this essay is trying to name.
## The Doctrine and Why It Matters
Eternal security is the claim that those whom God genuinely saves, he keeps. Not provisionally. Not contingent on a future that might unravel. The biblical witness on this is dense and consistent. Jesus says of his sheep in John 10: "I give them eternal life, and they shall never perish; no one will snatch them out of my hand." Paul, in Romans 8, ends his argument with a deliberate exhaustion of every possible threat — death, life, angels, demons, present, future, height, depth — and concludes that none of it "will be able to separate us from the love of God." Ephesians 1 speaks of believers being "sealed with the promised Holy Spirit," the seal being the ancient mark of ownership and protection.
This is not a peripheral comfort. It is a load-bearing wall. If the gospel announces that God has rescued me by sheer grace and that my standing before him rests on the finished work of Christ, then any suggestion that my salvation might unravel through some future failure of mine is, in effect, the gospel collapsing back into law. We would be saved by grace and kept by works. Anyone who has pastored long enough knows what that does to actual human beings: it produces either anxious legalists or exhausted apostates, and neither resembles the freedom Paul keeps describing.
So when my congregant says "the ticket's already punched," he has hold of something real and precious. The trouble is that he has hold of only one half of what Scripture says, and he is using that half to silence the other.
## What We Do with the Warnings
Because the other half is there, and it is not subtle. Hebrews 6 warns of those who have "shared in the Holy Spirit" and yet "fallen away." Matthew 7 records Jesus saying, "Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name?'" and his reply: "I never knew you." 1 John repeatedly draws a line between those who walk in the light and those who only claim to. 2 Peter speaks of dogs returning to their vomit. The warnings are everywhere, and they are not whispered.
And yet — and here I am implicating myself as much as anyone — pastors in churches that hold to eternal security have developed quiet habits of getting around them. The habits come in two main shapes.
The first is over-spiritualising. We read Hebrews 6 and immediately say, before the text has even finished speaking, "Of course these people were never really Christians in the first place." This may turn out to be theologically correct, but it functions as a way of refusing to feel the passage's weight. The writer of Hebrews evidently wanted his readers to feel something when they read those words. If our doctrinal grid causes us to neutralise the emotional and rhetorical force of the passage before it has done its work, we are not honouring Scripture; we are managing it.
The second is under-reading. This is the move where we acknowledge the warning passages exist, treat them with a kind of polite scriptural nod, and then preach around them. We choose Romans 8 for the funeral, John 10 for the assurance sermon, Ephesians 1 for the new members' class — and Hebrews 6 turns up roughly once a decade, on a Sunday when half the congregation is on holiday. The canon, in practice, gets edited. Nobody admits to doing this. Almost everybody does it.
The result is a pastoral culture so afraid of the shadow-side of assurance that it produces a generation of Christians for whom warnings have become emotionally inaudible. The ticket has been punched. The flight is booked. Move on.
## Hebrews 6 in the Room
Let me put the passage on the table and not move it.
"For it is impossible, in the case of those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt." (Hebrews 6:4–6)
Slow down. Enlightened. Tasted the heavenly gift. Shared in the Holy Spirit. Tasted the goodness of the word of God and the powers of the age to come. That is not the language we would expect to be applied to people who were merely religiously curious or hovering at the edge of a congregation. These are people whose Christian lives, from the outside and possibly from the inside, looked indistinguishable from genuine faith.
The cheap exit is to say, instantly: "Ah, but they hadn't really tasted, they'd only sort of half-tasted, and 'enlightened' doesn't really mean enlightened." This is exegetical embarrassment dressed up as careful theology. The writer chose these words deliberately. He is describing people who had every external mark of belonging — and who walked away, and whose walking away was so decisive that restoration is described as impossible.
The honest reading is harder and more useful. The writer is saying that participation in the visible life of the church — in its sacraments, its teaching, its experiences, even in spiritual gifts, does not, by itself, equal regeneration. There is a kind of belonging that is real in every social and experiential sense and yet, at some deeper level we cannot fully see, never was union with Christ. This is not a comfortable thought. It is not meant to be. The whole point of the passage is to make readers ask, with proper trembling, whether they are among those who have only tasted or among those who have eaten.
You cannot lose what you truly have. But you can have something that looks remarkably like it, and not have the thing itself. That is what Hebrews 6 is saying, and pretending it says less is a failure of nerve.
## The Difference Between Assurance and Presumption
Augustine, who thought harder about this than most, drew a distinction that has never really been bettered. There is, he said, a resting in God, which is the proper rest of the soul, the rest Christ promises in Matthew 11, and there is a resting in something about oneself, including in a past decision or experience one has had of God. The two feel similar from the inside and are radically different at root.
Resting in God means that the object of my confidence is God's character, God's promise, God's covenant faithfulness, God's having laid hold of me in Christ. Resting in a past decision means that the object of my confidence is something I once did or felt, a prayer, a hand raised, a baptism, a moment of conviction. The former is assurance. The latter is presumption.
The reason this matters is that the warning passages function very differently depending on which kind of confidence you have. If your confidence is in God, the warnings drive you deeper into him, they make you cling harder, pray more honestly, examine yourself not to despair but to be drawn back to the cross. If your confidence is in a past decision, the warnings are a threat to your settled position, and you will instinctively try to neutralise them. You will find a doctrinal mechanism that lets you keep your ticket and ignore the announcement.
My friend with the cheerful confidence about his ticket was, I think, somewhere in between. Most of us are. The warnings are not there to terrify the first kind of Christian. They are there to disturb the second kind into becoming the first.
## Perseverance Is the Evidence, Not the Cause
The Reformed tradition has a tidy way of putting this, and it is worth getting clear because it dissolves most of the apparent contradiction.
Those who are truly saved will persevere. Perseverance is not the cause of their salvation; it is the evidence of it. And the warning passages are not threats hung over genuine believers to keep them in line, they are one of the means by which God keeps his people in the faith. God preserves his saints, in part, by making them take warnings seriously. The doctrine of eternal security and the existence of the warning passages are not in tension; they are two angles on the same reality.
This is why the Westminster Confession can say, in the same breath, that true believers can never finally fall away and that they must "give all diligence to make their calling and election sure." The diligence is not a hedge against the doctrine. The diligence is the doctrine in motion. A genuinely saved person, hearing Hebrews 6, does not shrug and say "irrelevant to me." A genuinely saved person hears it and says, with David, "Search me, O God, and know my heart."
The mistake is to think the warnings are either threats that contradict assurance, or empty rhetoric that can be set aside because we know how it ends. They are neither. They are God's appointed means of keeping his people awake. The plane stays in the air partly because the warning lights work.
## The Pastoral Stakes in a Divided City
This is not abstract. Let me name some actual people, with the details rearranged enough to protect them.
A man I'll call James was a fixture in our church for about four years. He led a small group. He gave generously. He could pray in public with real warmth, and when he spoke about Christ at the front, people were moved. Then his marriage came apart, in a way that turned out to involve a long and deliberate pattern of deceit, and within six months he had left the church, left the faith, and was telling mutual friends that he had never really believed any of it, that it had been, for him, primarily a community and a moral framework. He had not been forced out. No one had been harsh with him. He simply walked, and four years later he has not walked back.
A woman I'll call Anna came to faith in her thirties from a background I won't describe except to say that the wreckage of it would have justified, in human terms, almost any quantity of bitterness. She has had two cancers, an unfaithful husband she stayed with, and a son who is in and out of prison. She is in church most Sundays. She is not a particularly impressive Christian in the categories the world recognises. She has endured.
What does the church owe these two people? It owes Anna the assurance that the God who began a good work in her will bring it to completion, and that nothing in the wreckage of her life can finally separate her from the love of God in Christ. It owes James, or owed him, when he was still listening, the honesty of Hebrews 6. Not as a weapon. Not as a threat. As the truthful warning of a writer who loved his readers enough to tell them that participation is not the same as possession, and that walking away from Christ after tasting his goodness is the most dangerous thing a human being can do.
A pastoral culture that preaches only assurance is unfair to Anna, because it cheapens what she has, and catastrophic for James, because it lets him sleep through a fire alarm. A pastoral culture that preaches only warning is cruel to both, because it withholds the gospel. We need both. The text gives us both. We should preach both.
## What Genuine Assurance Actually Feels Like
It is worth saying what genuine assurance is not, because the parody of it is so common that the real thing has become hard to recognise.
It is not the breezy confidence of the man with the punched ticket. It is not the inability to be troubled by one's own sin. It is not a settled certainty that derives from a moment in 1997 when one prayed a prayer at a youth event. These are not assurance, they are, at best, the absence of self-examination; at worst, presumption with a Christian vocabulary.
Genuine assurance has the texture of a child who knows their father. The child does not, on a normal day, worry whether they belong in the house, but they also do not boast about it. They simply live there. When they have done wrong, they are troubled, and they come and say so, and they are restored, and the restoration deepens rather than weakens their sense of belonging. They are not casual about the father's love because the father's love is the most real thing in the world to them. 1 John gives us tests, do we love the brothers, do we walk in the light, do we confess our sins, not so we can pass them and relax, but so we can see the contours of the life we actually have.
The Spirit, Paul says in Romans 8, "bears witness with our spirit that we are children of God." This is not loud. It is not always continuous. But it is the deepest form of confidence available to a human being, because its ground is not in us. And, this is the part that should settle the argument by itself, it produces holiness, not licence. The person who knows they are loved by the Father does not say "the ticket's punched, so I can do as I like." They say, with Paul, "How can we who died to sin still live in it?"
## Preach the Warnings, Protect the Doctrine
So here is the pastoral charge, mostly to myself.
Stop excising the hard passages. Stop quietly rotating Hebrews 6 to the back of the queue. Trust the congregation with the full grammar of grace, which includes its diagnostic edge as well as its embrace. Preach Romans 8 and Hebrews 6 in the same year, in the same series if you have the nerve, and do not soften either of them to make the doctrinal system tidier than the text. The text is not tidy. The text is true.
Let the warnings do the work God intended them to do. They are not threats against the saved. They are the alarm system that keeps the saved alert and that exposes the difference between those who have tasted and those who have eaten. Eternal security is not the claim that everyone who has ever been near the gospel will be saved. It is the claim that everyone whom God has actually saved, he will keep. The distance between those two claims is exactly where the warning passages live.
You cannot lose what you truly have. But you might never have had it. Both of those sentences come from the same Bible, and both of them need to be said.
"Examine yourselves, to see whether you are in the faith. Test yourselves. Or do you not realise this about yourselves, that Jesus Christ is in you?" (2 Corinthians 13:5)
