What Is the Spirit’s Work in Those Who Fall Away?

Question 04041.

Few questions unsettle a tender conscience like falling away, and few passages of Scripture stir more argument than Hebrews 6:4-6. There the writer describes people who were once enlightened, who tasted the heavenly gift, who shared in the Holy Spirit, and who tasted the goodness of the word of God, and yet fell away in the end. What exactly was the Spirit doing in such people, and what does their case mean for the rest of us who follow Jesus?

I take these warnings with full seriousness, and at the same time I hold firmly to the security of the true believer, grounded not in our own perseverance but in the faithfulness of God. Those two commitments are not in tension once we understand what the Spirit does, and does not do, in the people the writer of Hebrews has in view. The whole question of falling away rewards slow and careful thought, so let me take it gently and at some length, because hurried answers here have wounded a great many sincere souls.

The Passage That Raises the Question

The text in Hebrews 6:4-6 is stark, and it is meant to be. It is impossible, the writer says, to restore again to repentance those who have once been enlightened, who have tasted the heavenly gift and shared in the Holy Spirit, who have tasted the goodness of God’s word and the powers of the age to come, and who have then fallen away, since they are crucifying once again the Son of God to their own harm and holding Him up to contempt. The language could hardly be more severe.

Everything in the debate hangs on who exactly these people are. If they were genuinely regenerate believers who then lost their salvation for good, the comfort of the gospel would lie in ruins, for the same passage says flatly that they cannot be restored. If they were never truly saved at all, then we must explain carefully what it meant for them to share in the Holy Spirit and taste the powers of the age to come. The doctrine of falling away, and with it the assurance of every anxious Christian, lives or dies on reading these verses with patience rather than panic.

The Spirit Works Without Always Regenerating

The key that unlocks the passage is something I have argued elsewhere, that the Holy Spirit does several distinct things in human beings, and not every one of them is regeneration. He convicts the world concerning sin, righteousness, and judgement. He illuminates the mind so that truth is grasped and even welcomed for a season. He works powerfully in and around a believing community so that even those on its very edges feel His presence and taste His gifts. None of these works, taken on its own, amounts to the new birth.

A person can therefore share in the Holy Spirit, in the sense of partaking of His ministry and influence within the church, without ever being indwelt and sealed by Him as a child of God. The word translated shared, metochos, can mean partner or associate, one who participates alongside others, rather than one who possesses the thing in his own right. The warning describes people who came near to the fire and genuinely felt its warmth, not people in whom the fire of new life was actually burning. That distinction is the heart of any sound reading of falling away.

Tasting Is Not the Same as Feeding

The writer’s chosen verb repays close attention. These people tasted the heavenly gift and tasted the goodness of God’s word. To taste is to sample, to come to know something by real and not imaginary experience, and yet tasting is plainly not the same as eating and being nourished and living by it. A man may taste a fine meal and then spit it out untouched. The warning describes a genuine contact with the things of God, which is exactly why it is so solemn, and yet it stops short of ever saying that these people were born again.

Set the passage beside the parable of the soils in Matthew 13, and the picture sharpens. The rocky ground receives the word at once with joy, springs up quickly, and yet has no root in itself, so that when tribulation or persecution comes on account of the word, it immediately withers away. That is a real response, a genuine tasting, and it is not saving faith. The people of Hebrews 6 are that rocky ground, those whose experience of the Spirit’s work was real on the surface but never took root in a regenerated heart, and their falling away is the withering that follows a rootless springing up.

Falling Away Past the Point of Return

Why does the writer say such people cannot be brought back again to repentance? Not because God’s arm is too short to save them, but because of what they have done with the fullest possible light. Having seen and tasted the truth, and then deliberately turned from it, treating the Son of God with open contempt, they have hardened themselves past the point where any further argument or evidence will move them. They are not beyond grace by God’s reluctance to receive them, but by their own settled and final refusal of Him.

This is the same sobering reality Jesus pressed when He spoke of the sin against the Spirit that will not be forgiven. It is not that the Spirit runs out of patience by some arbitrary limit, but that a heart can so resist Him, over time and against such light, that it becomes immovable as stone. I have written separately on resisting the Holy Spirit, and the warning passages of Hebrews show us the most extreme picture in all of Scripture of where such resistance, followed by a deliberate falling away, can finally lead a soul. The horror of the passage is not capricious divine wrath; it is a man freely walking away from the only One who could ever have saved him.

Warnings Aimed at the True Believer

Here is something that is very often missed in the heat of the debate. The warning passages are not evidence against the security of the believer; they are one of the very means by which God keeps the believer secure. He warns His people in order to provoke them to press on, and the fact that a true child of God hears the warning, takes it to heart, and perseveres is part of how the warning actually does its appointed work. The threat is real, the danger is real, and the genuine believer is moved by it to keep clinging all the harder to Jesus.

Notice how the writer turns immediately to his readers in the very next breath after the terrible words about falling away. Though we speak in this way, he says in Hebrews 6:9, yet in your case, beloved, we feel sure of better things, things that belong to salvation. He plainly distinguishes the apostates of verses four to six from the believers he is addressing, whose love and work for His name God is not so unjust as to forget. The warning is published openly to all who hear; the assurance is spoken tenderly to the true. That is no contradiction; it is wise and loving pastoral care.

Why True Faith Cannot Finally Fall Away

I hold the security of the believer because the Scriptures ground it in God and never in us. The Spirit is given to the believer as a seal and as the arrabon, the down payment that legally commits the giver to deliver in full the inheritance promised. Jesus said in John 10:28 that those the Father gives Him He will never cast out, and that no one is able to snatch them out of His hand. The good work that God begins in a soul, He pledges Himself to complete.

So when John writes in 1 John 2:19 of those who went out from us, he immediately adds that they went out because they were not of us, for if they had been of us they would have continued with us. A departure of the final and unrepentant kind reveals what was always true of a person; it does not undo a genuine work of grace that was never there. The one who is truly born of God is kept by the power of God, and the falling away of the outward adherent is the painful unmasking of a faith that never once had the life of God in it. The sheep do not become goats; the goats are shown for what they always were.

How the Spirit Ministered to Them

It is worth pausing to say positively what the Spirit was doing in these people, since that is the precise form of the question. He was striving with them, as He strove with the men of Noah’s day. He was illuminating their minds so that they understood the gospel clearly, perhaps better than many who are saved. He was moving in the community around them with such power that they tasted the gifts and saw the wonders of the age to come breaking in. All of this is the Spirit’s genuine work, and all of it falls short of regenerating the soul.

That ought to make us both humble and watchful. A person may sit for years under sound preaching, feel deep emotion, defend the faith ably, and enjoy the fellowship of God’s people, and still not have been born again. The Spirit’s outward ministry can carry a man a very long way before the question of falling away ever arises, and the tragedy is precisely that he came so near. Nearness to the things of God is a mercy, but it is not the same as possessing God, and the warning of Hebrews exists to drive the near to become the saved before their hearts grow hard.

Comfort and Warning Held Together

How then do I counsel a worried believer who reads Hebrews 6 and trembles? I tell them that the very fact they are troubled by the danger of falling away is itself a hopeful sign and not a fearful one. The apostate of Hebrews 6 is not anxious about his soul in the least; he has hardened himself and walked away without a single backward glance. The trembling believer who runs back again to Jesus is doing the precise opposite of apostasy, and that running back is the Spirit’s work in a living heart.

And to the careless professor who presumes upon grace while flirting with the world, I say plainly that the warning is for you, and you should tremble at it. Take it as the gift it is, a firm hand laid on your shoulder, steering you back before the heart sets like concrete and cannot be moved. The same Spirit who warns so severely is the Spirit who keeps so faithfully, and the safest place in the world to stand under His warning is humble, ongoing, daily faith in Jesus. Fear that drives you to Christ is healthy; only the fear that drives you away from Him is to be feared.

What This Means for Watching Our Own Hearts

All of this should leave us tender rather than smug. The danger of falling away is never a club to swing at other people; it is a mirror held up to my own soul. If the Spirit can carry a man so far and yet leave him unregenerate, then I have every reason to make my own calling and election sure, and to keep coming back to Jesus rather than resting on a memory of past warmth. The falling away that Hebrews describes began, in every case, with a slow cooling that nobody troubled to notice at the time.

So I watch my heart, and I urge you to watch yours, not in panic but in honest love for the God who saved us. I have written on the Spirit’s quiet ministry of assurance, and that inward witness is the very thing the apostate never had and the true believer must never neglect. The cure for the fear of falling away is not less attention to it but far more attention to Jesus, who keeps every soul that keeps on coming to Him.

There is a great kindness hidden in the severity of these verses, and I do not want you to miss it. God could have left us to presume upon grace and drift quietly toward falling away without a word of warning, and instead He set this passage in the middle of His book like a lighthouse on a dangerous coast. The light is not there to torment the sailor but to keep him off the rocks. Read Hebrews 6 that way, as a mercy and not a threat, and the fear of falling away turns into one more reason to cling to the Saviour who holds you fast.

I have sat with more than one believer over the years who was tormented by these verses, convinced that some past coldness had put them beyond hope. In every case the cure was the same. We turned together from the dread of falling away back to the plain promises of Jesus, who said He would never cast out the one who comes to Him. The terror lifted, not because we explained the warning away, but because we let it do its proper work of driving a frightened sheep back into the arms of the Shepherd.

So, now what?

If you are frightened that you may already have fallen away, hear this carefully. Your fear is not the mark of the hardened apostate but of the wandering sheep who wants to come home. Run to Jesus again, today, just as you are. He has never once turned away a sinner who came to Him in faith, and He will not begin the practice with you.

If you have grown careless, treating grace as a licence and the things of God as old and tired news, then let the warning land on you with its full weight. The Spirit is speaking to you through it, and a soft heart today is a far better and safer thing than a hardened one tomorrow. Keep clinging to Jesus, because the One who holds you is faithful even on the days when you are weak, and He will not let go.

And we desire each one of you to show the same earnestness to have the full assurance of hope until the end, so that you may not be sluggish, but imitators of those who through faith and patience inherit the promises.

For Further Study

For those who wish to read further, the warning passages of Hebrews are handled at length by the classic evangelical writers. Charles Ryrie and J. Dwight Pentecost both treat the security of the believer within a dispensational frame, while Lewis Sperry Chafer gives sustained and careful attention to the Spirit’s varied work in the unregenerate. Millard Erickson surveys the main interpretive options on Hebrews 6 fairly and at length, and Arnold Fruchtenbaum is useful on the way the Spirit ministered to the wider community of Israel without indwelling every individual within it. Reading any of them slowly, with the text of Hebrews itself open alongside, will repay the effort many times over.
