The Christian Life Is Not a Straight Line
If you’re still fighting the same battles you were fighting five years ago, that doesn’t mean your faith is broken. It means you’re human.
Scripture: Romans 7:15–25; Galatians 5:16–17; Philippians 3:12–14; 1 John 1:8–10; Lamentations 3:22–23
Nobody tells you this clearly enough at the beginning.
You become a Christian — or you recommit, or you return after a long absence, or you simply find yourself still believing after everything — and somewhere in the early days there is usually a season that feels like momentum. Things that used to feel impossible feel possible. Old patterns seem to be loosening. There’s something that feels like progress.
And then, eventually, you fight a battle you thought you’d already won. You repeat a pattern you were certain you’d broken. You discover that the part of you that was supposed to be changing hasn’t changed as much as you thought.
And the question that follows, quietly or loudly, is: what does that mean about me? About my faith? About whether any of this is working?
Here’s what it means: you’re human. The Christian life does not move in a straight line.
What we were led to expect
The straight-line version of the Christian life is everywhere. It’s in the conversion testimonies where everything is before and after. It’s in the language of spiritual growth that implies consistent upward movement. It’s in the way certain sins get spoken of as old-life things — things Christians used to do, past tense, over.
The straight-line version isn’t entirely wrong. Growth is real. People change. The Spirit is genuinely at work. There are things that, over time, genuinely lose their grip.
But the Christian life doesn’t move the way a progress chart moves.
It moves more like weather.
There are seasons of clarity and seasons of fog. Periods where the practices feel alive and periods where they feel like going through motions. Years where a particular sin loses its hold and years where it comes back with a ferocity you weren’t prepared for. Stretches of something that feels like flourishing and stretches of something that feels like barely holding on.
This is not a sign that something has gone wrong. It’s a description of what the tradition has always called sanctification — the ongoing work of God in a human life — and it has never been a straight line for anyone.
What Paul actually said
The most honest account of the interior Christian life in the New Testament is Romans 7, and it’s startling how often it gets explained away.
Paul writes: “I do not do what I want, but I do the very thing I hate” (Romans 7:15). And: “I have the desire to do what is right, but not the ability to carry it out” (Romans 7:18). And: “I find it to be a law that when I want to do right, evil lies close at hand” (Romans 7:21).
Whatever you make of the precise context of that passage, the experience it describes is recognizable to every honest Christian who has ever tried to live faithfully. The wanting-but-not-doing. The knowing-better-but-not-managing-it. The discovery that becoming a Christian doesn’t instantly collapse the gap between desire and performance.
Paul doesn’t describe this as a failure of faith. He describes it as the condition of a human being who has been given new life but has not yet been given the final resurrection — who lives in the overlap between what God has declared and what the body still carries. That overlap is uncomfortable. It’s supposed to be. It’s also not supposed to be the last word.
Galatians 5 puts it plainly: “The desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do” (Galatians 5:17). This conflict isn’t a sign that the Spirit has lost. It’s a sign that the Spirit is present. You can’t have the battle without both sides being real.
The two wrong responses
When the straight line doesn’t materialize, people tend toward one of two responses. Both are understandable. Both are wrong.
The first is despair. If I’m still struggling with this, I must not really be saved. If my faith were genuine, it would be producing more visible change by now. The ongoing struggle becomes evidence of a verdict.
The second is resignation. I’ve tried and it hasn’t worked, so this is just who I am. I’ll believe the doctrines and show up on Sundays but I’ve stopped expecting the inner life to change.
Both responses stop the motion. Despair collapses inward. Resignation goes flat. And both are based on a false picture of what the Christian life is supposed to look like.
The tradition — not the sanitized version, but the honest one — describes a third path. It doesn’t pretend the struggle isn’t real. It doesn’t promise the struggle will end before death. But it keeps moving through the struggle rather than stopping at it. It returns after failure without treating failure as final. It continues practicing the means of grace — prayer, Scripture, community, sacrament — not because those practices produce a guaranteed result but because the God who is met in them is the God who is working the change.
What growth actually looks like
Real growth in the Christian life tends to be less visible than you expect and more gradual than it feels from inside.
It looks less like a conquering of sin and more like a slow shift in what you desire. Not the absence of temptation but a changing relationship to it. Not the elimination of failure but a shortening of the distance between failure and return.
It looks like the ability to grieve sin more honestly rather than manage it more successfully. That might sound like regression, but it isn’t. The person who can name what went wrong with clarity and sorrow and come back to God without either minimizing or catastrophizing has grown into something the person performing effortless sanctification has not.
It looks like a decreasing need to be seen as doing well. As the grip of shame loosens — slowly, over years — the energy that was spent managing appearances becomes available for something more honest. That’s growth. It doesn’t make the highlights reel.
And it looks like a longer arc than you thought. The things that seem urgent and immediate in the early years of faith often turn out to be the work of decades. The tradition doesn’t actually promise quick transformation. It promises faithful accompaniment through a long, nonlinear process.
When you’re in the middle of a hard stretch
If you’re reading this in a season where the struggle feels acute — where you’ve failed at something you thought you’d gotten past, where the practices feel empty, where the faith that once felt alive has gone quiet — a few things are worth holding onto.
The struggle is not proof of absence. The fact that you’re still fighting means something is still fighting. If the Spirit weren’t present, there would be no conflict — only giving in. The battle itself is evidence of life.
Return is always possible. Not after sufficient penance. Not once you’ve demonstrated you’ve learned your lesson. The father in Luke 15 runs. The prodigal hasn’t finished the speech before the robe is being brought out. The return — honest, without performance — is always possible and always received.
The practices are still worth doing. Prayer that feels empty is still prayer. Scripture read in a season of dryness still lands somewhere. Showing up for worship when you’d rather not isn’t hypocrisy — it’s the body arriving before the feeling does, which is sometimes the most faith you have, and sometimes that’s enough.
Other people have been here. The psalmists wrote entire psalms from inside this experience — not as a detour on the way to something better, but as their actual condition before God, named honestly and brought into the open. The mystics called it the dark night. Luther, who gave us the most rigorous theology of grace in the Western tradition, described the Christian life as a daily return to baptism — not a progress beyond the beginning, but a repeated coming back to the only thing that was ever firm.
You are not the first person to be here. You won’t be the last. And the God who declared you his own didn’t do it on the assumption that you would be further along by now.
The mercies are new every morning. Not every year. Every morning. Lamentations 3:22–23.
