What is definitive sanctification versus progressive sanctification?

Question 7072.

Progressive sanctification is the part of this doctrine most Christians have heard about, and it is the part that feels true to experience. We are being changed, slowly, unevenly, over a lifetime. What fewer believers have been taught is that Scripture also speaks of sanctification as something already accomplished, finished, and never to be repeated. Both are in the New Testament, and confusing them causes real trouble.

So let me lay the two out side by side, show where each comes from in Scripture, and explain why the pastoral value of the doctrine depends on keeping them in the right order.

The word before the categories

The underlying idea behind sanctification is separation. The Greek noun hagiasmos and its family describe being set apart for God’s use. In the Old Testament the vessels of the tabernacle were sanctified, and nobody imagined the bowls were becoming morally better. They had been transferred out of ordinary use into God’s service.

That root meaning is the key to the whole subject. Sanctification is fundamentally about ownership and purpose, and only derivatively about behaviour. Behaviour changes because ownership has changed, not the other way round.

Once that is clear, the two categories fall into place naturally rather than looking like a theologian’s invention. I have set out the broader ground in the article on what sanctification is.

Definitive sanctification: already done

Definitive sanctification is the once for all setting apart of the believer at the moment of conversion. Paul writes to the Corinthians, a congregation with spectacular behavioural problems, and calls them sanctified in Christ Jesus. He tells them in 1 Corinthians 6:11 that they were washed, sanctified and justified, all in the past tense, and he says it after listing the sins they had come out of.

Hebrews puts it even more sharply. Hebrews 10:10 says that by God’s will we have been sanctified through the offering of the body of Jesus once for all. That is not describing gradual improvement. It is describing a transfer of status accomplished by the cross, complete at the moment faith unites us to Him.

This is why the New Testament can address ordinary struggling believers as saints. The title is not a compliment on their progress. It is a statement about whose they are. I have written more on that in the piece on positional and practical sanctification, which covers closely related ground with a slightly different emphasis.

Progressive sanctification: still happening

Progressive sanctification is the ongoing work of the Holy Spirit conforming the believer to the likeness of Jesus across the whole of life. Paul prays in 1 Thessalonians 5:23 that God would sanctify them completely, spirit and soul and body, which would be a strange prayer if nothing further remained to be done.

Here the language is of growth, pursuit, striving, putting off and putting on. Progressive sanctification involves my will in a way that definitive sanctification never did. I was not asked to cooperate with being set apart. I am very much asked to cooperate with being changed.

That cooperation is not self improvement with a religious label. Philippians 2:12 and 13 holds the two sides together with a precision I have never managed to improve on: work out your own salvation with fear and trembling, for it is God who works in you. My effort is real. His power is prior. See also how the Spirit sanctifies.

Why the order matters so much

Take the two doctrines in the wrong order and the Christian life becomes an audition. If progressive sanctification is the ground of my standing, then every bad week threatens my acceptance, and every good week inflates me. That is not the gospel, and it does not produce holiness. It produces anxiety and pride in alternating shifts.

Take them in the right order and something quite different happens. Because I am already set apart and cannot become more or less God’s possession, the work of progressive sanctification is safe work. I can look honestly at my sin, because looking does not endanger me. Confession becomes possible in a way it never is under a performance system.

This is the pattern of New Testament exhortation everywhere. You are dead to sin, therefore consider yourselves dead to sin. The indicative precedes the imperative. Progressive sanctification is always commanded on the basis of what is already true, never as a way of making it true.

Common confusions worth clearing

Some traditions have taught a second experience that completes sanctification instantaneously, sometimes called entire sanctification. I do not find it in Scripture. The New Testament letters were written to believers who had been converted years earlier and still needed telling to stop lying, stop stealing and control their tongues, which is difficult to reconcile with a completed inward purification available in this life. I have dealt with the question of sinless perfection separately.

Others collapse the categories in the opposite direction, treating sanctification as purely positional and treating any talk of growth as legalism. That will not survive contact with the epistles either. Peter tells his readers to grow, and growth is not a positional word.

There is also a third and final stage which neither category covers. Glorification finishes what progressive sanctification begins, and it happens not by effort but by sight. We shall be like Him, because we shall see Him as He is.

What this looks like on a Tuesday

In practice this doctrine changes how I handle failure. When I sin, definitive sanctification tells me what has not changed: I am still His, still set apart, still welcome. Progressive sanctification tells me what still needs to change and gives me the Spirit’s help to change it. Neither truth is dispensable at that moment.

It also changes how I measure progress. Progressive sanctification is rarely visible week to week, and comparing yourself to last Tuesday will only discourage you. Look across five years instead. Ask whether sin grieves you more than it did, whether Scripture tastes different, whether you forgive more readily. Those are the instruments that register real movement.

And it changes how I look at other believers. The person in the next pew who is struggling badly may be further along the road of progressive sanctification than I am, given where they started. That thought has silenced a good deal of my private commentary over the years.

How the two aspects work together in practice

Take a believer wrestling with a temper. Definitive sanctification tells him that he belongs to God, that his standing is settled, and that his identity is not defined by the failure he committed on Tuesday. Progressive sanctification tells him that the temper can genuinely change, that the Spirit is at work on it, and that the change will come through obedience in the moment rather than through resolutions in the abstract.

Remove the first and he fights out of fear, which produces suppression rather than transformation. Remove the second and he shrugs, which produces nothing at all. Held together, they produce a man who confesses quickly, gets up again, and finds after five years that the thing has genuinely loosened.

That is the ordinary shape of Christian growth, and it is unspectacular. I have come to distrust accounts of sanctification that promise a shortcut, whether by a single crisis experience or by a technique. The New Testament offers means rather than mechanisms: Scripture, prayer, the local church, obedience, and time.

Where the Spirit and our effort meet

People often ask whether sanctification is God’s work or ours, expecting me to choose. It is both, and the New Testament never treats that as a contradiction. Paul says he worked harder than any of them, and then says it was not him but the grace of God with him, in the same breath and without apology.

The picture I find most helpful is a sail rather than an oar. The power is not mine, and my job is to put up the canvas. Reading Scripture, gathering with God’s people, praying, obeying the thing I already know, keeping away from what I know undoes me: these are not achievements, they are exposure to the wind.

And the wind does blow. That is the confidence underneath the effort. Philippians promises that He who began a good work will bring it to completion, which means my sanctification is not finally dependent on my consistency. Thank God, because my consistency would not carry it.

The end of the process

It is worth naming where all of this is going, because progressive sanctification is not endless. Glorification completes it, and the completion comes by sight rather than by striving. John says we shall be like Him because we shall see Him as He is, and Paul says the body sown in weakness is raised in power. Every believer who has ever fought a losing battle against a besetting sin will win it finally, and the victory will be given rather than earned.

So, now what?

If you tend towards despair, spend a fortnight in the past tenses. Read 1 Corinthians 1:2, Hebrews 10:10 and Romans 6:1 to 11 slowly, and notice how much has already been settled about you. You are not trying to become God’s. You are His.

If you tend towards complacency, spend the same fortnight in the imperatives, and ask the Spirit to show you one specific thing to put off and one specific thing to put on. Progressive sanctification does not happen in the abstract. It happens in the particular, and usually in the places we would rather not examine. Which one is God pressing on at the moment?

And by that will we have been sanctified through the offering of the body of Jesus Christ once for all. (Hebrews 10:10)
