What is the Spirit’s work in those who fall away?
Question 04041
Few passages in the New Testament have generated more theological controversy than Hebrews 6:4-6. Here the writer describes people who have been “enlightened,” who have “tasted the heavenly gift,” who have “shared in the Holy Spirit,” and who have “tasted the goodness of the word of God and the powers of the age to come” and yet have “fallen away.” What exactly was the Spirit’s work in these people? And what does this passage actually mean? The stakes are high, because the answer touches directly on questions about salvation, security, and the nature of genuine spiritual experience.
The Spirit Can Work Without Regenerating
A foundational observation is that the Holy Spirit does several different things in human beings, and not all of them constitute regeneration. He convicts the world of sin, righteousness, and judgement (John 16:8). He illuminates the mind so that spiritual truth can be comprehended. He draws people toward Christ. He can operate powerfully in someone’s life, produce genuine spiritual impressions, and even prompt genuine responses, all without that person having been born again. Recognising this range of the Spirit’s ministry is essential for understanding what Hebrews 6 is and is not describing.
The language the writer of Hebrews uses is deliberate and worth examining carefully. The people described have been “enlightened” — the Greek is phōtizō (φωτίζω), meaning to bring into the light, to make visible. This is a real experience of spiritual illumination. They have “tasted the heavenly gift” — the verb geúomai (γεύομαι) indicates genuine experience, not mere exposure. They have “shared in the Holy Spirit” — the Greek metochos (μέτοχος) is used elsewhere in Hebrews to describe genuine participation, as in 3:14 where it describes those who “share in Christ.” They have tasted “the goodness of the word of God and the powers of the age to come.”
This is not a description of someone who merely sat in a church building or heard a sermon in passing. These are people who had a genuine, sustained encounter with the Spirit’s ministry. But the question remains: does this mean they were regenerate?
What the Text Does Not Say
Hebrews 6 does not use the language of regeneration, of new birth, of being indwelt by the Spirit, or of union with Christ. These are the terms the New Testament reserves for describing believers who genuinely belong to God. The passage also does not describe these people as having trusted Christ for salvation, as having been justified, or as having received the Spirit as a permanent dwelling. What it describes is a rich and real encounter with the Spirit’s external work, short of the Spirit’s regenerating, indwelling, sealing work.
This distinction is not a theological escape route invented to protect a doctrine. It reflects the Spirit’s actual ministry as the New Testament describes it. In Acts 7:51, Stephen accuses the Sanhedrin of “always” resisting the Holy Spirit — language that only makes sense if the Spirit had been genuinely at work in them, pressing on their consciences, illuminating truth to them, without regenerating them. The Spirit can be resisted. His convicting, drawing, enlightening work can be persistently rejected.
The Significance of 1 John 2:19
John’s first letter provides a hermeneutical window that helps interpret Hebrews 6. Writing about those who had left the Christian community, John says: “They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us” (1 John 2:19). The departure itself was evidence that genuine belonging had never existed. The people who fall away in Hebrews 6 are the same category of person: those who experienced the Spirit’s ministry powerfully but were never truly regenerate.
This is not a comfortable conclusion to reach, precisely because the experiences described in Hebrews 6 sound so significant. But the New Testament elsewhere makes it clear that religious experience, even intense and apparently spiritual experience, does not guarantee genuine salvation. Jesus himself warned in Matthew 7:21-23 that on the day of judgement there would be those who had prophesied, cast out demons, and performed mighty works in his name, and yet had never truly known him.
Why “Impossible to Restore”?
The sobering statement that it is “impossible to restore them again to repentance” raises its own questions. The writer’s point appears to be that someone who has been so thoroughly exposed to the Spirit’s ministry, who has experienced so much of the Spirit’s work, and who has then turned away in deliberate rejection, has reached a point of wilful hardening that precludes genuine repentance. They have not simply drifted. They have seen what they needed to see and have rejected it with open eyes.
The writer’s purpose throughout Hebrews 6 is not primarily doctrinal but pastoral. He is warning a Jewish Christian community against the particular danger of abandoning Christ and returning to the old covenant system. The “falling away” he describes is not casual moral failure but a decisive, public repudiation of Jesus in favour of a Judaism that had already condemned him. The warning is real and serious, and it is intended to produce perseverance, not paralysis.
The Spirit’s Work and Genuine Assurance
This passage is sometimes used to undermine the assurance of believers, but that is precisely the opposite of the writer’s intention. Immediately after the warning, he writes: “Though we speak in this way, yet in your case, beloved, we feel sure of better things — things that belong to salvation” (Hebrews 6:9). The warning is given to the community; the confidence is expressed for genuine believers. Real assurance does not rest on the intensity of past spiritual experience but on present faith in Christ and the continuing witness of the Spirit (Romans 8:16). The Spirit who indwells believers bears witness with their spirit that they are children of God. That witness is ongoing and sustaining, not a memory of a past encounter.
So, now what?
Hebrews 6 is not designed to make believers lie awake in dread. It is designed to make those who are spiritually coasting take stock. If you are genuinely trusting Christ, the warning passages of Hebrews are not addressed to your condition. But if you have experienced much of the Spirit’s work, know the truth of the gospel thoroughly, and have been coasting on religious familiarity without genuine personal trust in Christ, the passage deserves your full attention. The Spirit’s external work in your life is evidence of His patience and grace, not a guarantee of your standing before God. What is needed is not more religious experience but genuine, personal faith in Jesus Christ, and the new birth that the Spirit brings to those who receive him.
