Growth Belongs to God

What Scripture says about spiritual formation, why transformation takes longer than you were told, and the daily practice that carries it.

Last Updated: July 2026

There is probably a shelf in your house like the one in mine. Books underlined twice. One finished in a single weekend because it named something you had been carrying for years. Sermons saved to a folder you have not opened. A journal with eleven good entries and then a gap. And you are roughly the same person. Not entirely. You know more than you did and you can explain things now. But the quiet reordering of who you are has mostly not happened, and somewhere underneath the reading sits a suspicion that this works on other people. Information was never going to change you. Formation happens through repetition in a direction, over time, and the growing part belongs to God. Your job is smaller and more ordinary than you would like. Plant, water, return.

What Transformation Actually Is

Read the grammar of the most quoted verse on this subject, because the grammar is the teaching.

Do not conform to the pattern of this world, but be transformed by the renewing of your mind. ~Romans 12:2

Be transformed. Paul puts the action on someone else and leaves you in the position of the one it happens to. The same shape appears when he describes the process from inside.

And we all, who with unveiled faces contemplate the Lord’s glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit. ~2 Corinthians 3:18

Are being transformed. Present tense, ongoing, done to you. You contemplate. He transforms. And the phrase at the end gives the shape of the whole thing: ever-increasing glory, which is a spiral rather than a finish line.

Paul reaches for one more word, the one behind our word metamorphosis, and he uses it while writing to a church that had gone backward.

My dear children, for whom I am again in the pains of childbirth until Christ is formed in you. ~Galatians 4:19

Notice the arrangement. Paul casts himself as the one in labor. The Galatians are the place where the forming happens. Christ is the one being formed. Nobody in that picture is forming themselves.

Plant, Water, Return

Here’s the passage that reorganizes the whole subject, and Paul writes it while settling an argument about which teacher deserved credit for a church.

I planted the seed, Apollos watered it, but God has been making it grow. So neither the one who plants nor the one who waters is anything, but only God, who makes things grow. ~1 Corinthians 3:6-7

Look at how the labor divides. Two men worked. Both did real work. Neither of them grew anything.

Growth belongs to God, and He is doing it continuously, including through the long stretches when you can detect nothing at all. Your part is planting and watering, which are unremarkable, repeatable, and entirely within reach on a Tuesday. You cannot make yourself grow, and God hasn’t asked you to. He’s asked you to stay where the water is.

Jesus says the same thing to His friends on the last night, and He makes it an instruction.

Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me. ~John 15:4

Remain. That’s the verb, and it’s the least dramatic one available. A branch produces nothing by effort and everything by attachment, and the whole of its work is staying joined to what’s already alive.

This is why striving fails here in a way it doesn’t fail elsewhere. In most of life, effort produces proportional results. In formation, effort produces the conditions, and Someone else produces the growth, on His timeline, often in an area you weren’t monitoring.

Which is also why you can stop auditing yourself for evidence.

That person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither. ~Psalm 1:3

The tree is positioned, and it stays there, and the fruit arrives in season rather than on demand. Position, then time. A tree doesn’t check.

What You Can Do

Scripture’s instruction to us is training language, and it’s more athletic than most of us expect.

Train yourself to be godly. For physical training is of some value, but godliness has value for all things. ~1 Timothy 4:7-8

The word behind "train" is the one that gives us "gymnasium". Paul assumes practice, repetition, and a program. The writer of Hebrews says the same about discernment and locates it in accumulated use.

But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil. ~Hebrews 5:14

By constant use, discernment is built the way a callus is, by returning to the same work until the capacity is there. Two findings from the research on how people sustain a practice are worth knowing here. The first is that deciding when and where to follow through sharply increases the likelihood of follow-through. A vague intention to read Scripture more converts poorly. A specific one, tied to something already fixed in your day, converts far better. Before coffee. After the school run. The chair by the window.

The second is one of the most durable findings in learning research: the same material spread across time is retained far better than the same material taken all at once. A weekend intensive feels transformative and mostly evaporates. Fifteen minutes daily feels like nothing and compounds.

Why You Have to Meet It More Than Once

Here’s what explains the years between understanding a truth and being changed by it. You’ve had the experience of opening a passage you already knew and finding something in it that wasn’t there before. The verse didn’t change. You arrived at it as a different person, carrying a different year, and it opened accordingly. That’s what ever-increasing glory describes. Formation moves in a spiral. You return to the same ground at a different height, and the return is the mechanism itself. Trust met in an easy season, and trust met in a hard one are the same word and two different educations.

This has a practical consequence, and it explains why most devotional books quietly stop working. A book that treats each subject once, moves on, and never comes back can teach you a great deal. Forming you is another matter, because a single exposure to trust leaves a person unchanged in trust. You have to meet it in the spring and meet it again in the winter.

There is probably a shelf in your house like the one in mine. Books underlined twice. One finished in a single weekend because it named something you had been carrying for years. Sermons saved to a folder you have not opened. A journal with eleven good entries and then a gap.

And you are roughly the same person.

Not entirely. You know more than you did and you can explain things now. But the quiet reordering of who you are has mostly not happened, and somewhere underneath the reading sits a suspicion that this works on other people.

Information was never going to change you. Formation happens through repetition in a direction, over time, and the growing part belongs to God. Your job is smaller and more ordinary than you would like. Plant, water, return.

What Transformation Actually Is

The grammar of the most quoted verse on this subject is the teaching.

Do not conform to the pattern of this world, but be transformed by the renewing of your mind. ~ Romans 12:2

Be transformed. Paul puts the action on someone else and leaves you in the position of the one it happens to. The same shape appears when he describes the process from inside.

And we all, who with unveiled faces contemplate the Lord’s glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit. ~ 2 Corinthians 3:18

The tense is present and the action is still being done to you. You contemplate. He transforms. And that closing phrase, ever-increasing glory, gives the shape of the whole thing: a spiral.

Paul reaches once more for the word behind our word metamorphosis, writing to a church that had gone backward.

My dear children, for whom I am again in the pains of childbirth until Christ is formed in you. ~ Galatians 4:19

Paul casts himself as the one in labor. The Galatians are the place where the forming happens. Christ is the one being formed. Nobody in that picture is forming themselves.

The Twenty-One Day Problem

Somewhere along the way you were told a habit takes twenty-one days.

That number came from a plastic surgeon in the 1960s who noticed his patients took about three weeks to get used to seeing a new face in the mirror. He was describing how long it takes to adjust to an altered body. It got repeated, then simplified, then hardened into a rule that has discouraged more people than almost any other piece of self-help arithmetic.

When researchers finally measured it, tracking ninety-six people forming ordinary daily habits, the median came in at sixty-six days. The range ran from eighteen days to two hundred and fifty-four. Two women doing the same practice with the same sincerity can be two hundred days apart, and neither of them is failing.

Two weeks in, nothing feels different, and the whole enterprise starts to look like something other people are better at. That is where almost everyone stops. Two weeks is nowhere near where you find out, and the sensation that nothing was happening is exactly what the evidence predicts.

The discouragement was built on a bad number.

Plant, Water, Return

Paul settles an argument about which teacher deserved credit for a church, and in settling it he explains the whole subject.

I planted the seed, Apollos watered it, but God has been making it grow. So neither the one who plants nor the one who waters is anything, but only God, who makes things grow. ~ 1 Corinthians 3:6-7

Two men worked, both of them really worked, and neither of them grew anything.

Growth belongs to God, and He is doing it continuously, through the long stretches when you can detect nothing at all. Your part is planting and watering, which are unremarkable, repeatable, and within reach on a Tuesday at six in the morning. You cannot make yourself grow. God has asked you to stay where the water is.

Jesus said the same thing to His friends on the last night, and He made it an instruction.

Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me. ~ John 15:4

The entire work of a branch is staying joined to something already alive. The fruit follows from the joining.

This is why striving fails here in a way it does not fail elsewhere. In most of life, effort produces proportional results. In formation, effort produces the conditions, and Someone else produces the growth, on His timeline, often in an area you were not watching.

You can stop auditing yourself for evidence.

That person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither. ~ Psalm 1:3

A tree doesn’t check.

Train

Scripture’s instruction to us is training language, and it is more athletic than most of us expect.

Train yourself to be godly. For physical training is of some value, but godliness has value for all things. ~ 1 Timothy 4:7-8

The word behind train is the one that gives us gymnasium. Paul assumes practice, repetition, and a program. The writer of Hebrews says the same about discernment and puts it down to accumulated use.

But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil. ~ Hebrews 5:14

Discernment gets built the way a callus gets built, by returning to the same work until the capacity is there.

Two things worth knowing from the research on how people sustain a practice.

A general intention to read Scripture more converts poorly, and the same intention attached to something already fixed in your day converts far better. The chair by the window. The mug you always use. Before the phone comes on.

And material spread across time is retained far better than the same material taken all at once. A weekend intensive feels transformative and mostly evaporates. Fifteen minutes on a Tuesday feels like nothing at the time, and it is the one still with you in March.

Which returns us to the shelf. You read those books in weekends.

Why You Have to Meet It More Than Once

You have opened a passage you already knew and found something in it that was not there before. The verse did not change. You arrived at it as a different person, carrying a different year, and it opened accordingly.

That is what ever-increasing glory describes. Formation moves in a spiral, returning to the same ground at a greater depth, and the returning is the mechanism. Trust met in an easy season and trust met in a hard one are the same word and two different educations.

Most devotional books quietly stop working for this reason. A book that treats a subject once and moves on can teach you a great deal. Forming you takes more, because trust met a single time stays a concept. You have to meet it in the spring and meet it again in the winter.

Begin This Week

Something small enough to start tonight.

Choose the time and the place, and choose them now. The chair by the window, after the coffee, before anyone else is awake. Deciding when and where is the highest-leverage move available to you and it costs nothing but the deciding. Then make it smaller than feels right. Ten minutes. One passage. The instinct to begin with an hour is the same instinct that produced the eleven entries.

Two things to hold alongside it:

Read the same passage twice in one week, Monday and again Thursday, and notice what moved between them. That difference is you.

Put a date on the calendar sixty days out and agree with yourself to leave the whole question alone until you reach it. You will want to check.

You will also miss days. Missing a day ends nothing, and the only real failure available here is deciding that missing means you are not the kind of person who does this.

None of that requires anything from me.

One more thing, for the suspicion sitting underneath all of this.

Being confident of this, that he who began a good work in you will carry it on to completion until the day of Christ Jesus. ~ Philippians 1:6

He began it. Before the books, before the journal, before this page. It is already underway in you, the carrying is His to do, and the completion runs to the day of Christ, which means it was never going to be finished this year.

The books on your shelf did their work. They gave you words for what you have been reaching toward, and that is worth something.

What comes next is quieter and takes longer. You put yourself near the water and you stay, and the growing is done by Someone who began it long before you noticed.

One morning at a time.

With love, Ari’yah

Common Questions

How long does spiritual transformation take? Longer than the popular numbers suggest, and the variation between people is enormous. Scripture calls the whole of it lifelong.

Why haven’t I changed after reading so many books? Reading gives you understanding, which is real and worth having. Formation asks you to return to the same truths across seasons until they have reshaped how you live. Distributed practice beats intensive consumption by a wide margin, which is why the weekend that felt life-changing left so little behind.

What’s the difference between spiritual disciplines and legalism? The direction of the work. Discipline plants and waters and waits on God for the growth. Legalism attempts to produce the growth itself and then measures the result to establish standing. The practices are frequently identical, and the difference is invisible from outside, which is part of why this one stays hard.

The twenty-one-day figure traces to Maxwell Maltz, a plastic surgeon writing in 1960 about how long his patients took to adjust to a changed appearance. The habit research by Phillippa Lally and colleagues followed ninety-six people over twelve weeks: sixty-six days to automaticity at the median, with a range from eighteen to two hundred and fifty-four. The finding on deciding when and where is Peter Gollwitzer’s work on implementation intentions. The finding on spacing comes from the distributed practice literature, which has among the most replicated results in learning research.

A year of daily readings built on all of this is nearly finished. I’ll write about it on its own.

Begin This Week

Before you decide whether any of this is for you, here is something small enough to start tonight.

Choose the time and the place, and choose them now. Not “more Scripture.” The chair by the window, after the coffee, before the phone. Deciding when and where is the highest-leverage move available to you, and it costs nothing but the deciding.

Make it smaller than feels right. Ten minutes. One passage. The instinct to begin with an hour is the same instinct that produced the eleven entries.

Return to the same passage twice in one week. Read it Monday, read it again Thursday, and notice what moved. That difference is you.

Give it sixty days before you evaluate. Put a date on the calendar two months out and agree with yourself to leave it alone until then. You’ll want to check.

Let it be interrupted. You’ll miss days. Missing a day ends nothing, and the only real failure available here is deciding that missing means you aren’t the kind of person who does this.

None of that requires anything from me. If you do only that, this article has done its work.

With love,
