Why Do I Keep Sinning Even Though I’m a Christian?

“For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate.” — Romans 7:15 (ESV)

A few verses later, Paul says it again:

“For I do not do the good I want, but the evil I do not want is what I keep on doing.” — Romans 7:19 (ESV)

Sound familiar?

If you are a Christian wondering why you keep doing things you know are wrong, you are not the first person to ask the question. Paul described the conflict two thousand years ago.

You believe in Jesus Christ. You know what Scripture says. You pray. You may attend church, read your Bible, worship, and genuinely want to live differently.

Yet there are things you keep doing that you know you shouldn’t.

Maybe it is anger, resentment, lust, dishonesty, pride, jealousy, unforgiveness, defensiveness, gossip, avoidance, or something else. You have confessed it. You have promised yourself you will do better. You may have asked God repeatedly to take it away.

Then the situation happens again, and before you know it, you have done the same thing.

That can lead to a frightening question:

If I am really a Christian, why do I keep sinning?

For some people, the question goes even deeper:

Was I ever really saved?

Before you reach that conclusion, there is something important about Christian growth that you need to understand.

Salvation Did Not Erase Everything You Had Already Become

When you trusted Christ, something real happened. Salvation isn’t simply deciding to become a better person. The Christian receives new life in Christ, and the Holy Spirit begins a work that was not there before.

But you did not cease being you.

Before you ever became a Christian, you had already spent years learning how to live.

You learned what you liked and disliked. You learned what brought comfort and what caused discomfort. You learned how to protect yourself, defend yourself, get approval, avoid embarrassment, deal with fear, respond to anger, get what you wanted, and cope when you couldn’t.

You also learned to predict outcomes.

If I do this, that will probably happen.

If I say this, that person will probably respond this way.

If I admit what I did, there will probably be consequences.

If I don’t defend myself, people may believe what was said about me.

None of that necessarily requires conscious thought anymore.

You have practiced many of these responses for years. Some have become habits. Some have become part of your character.

That matters because salvation does not instantly erase a lifetime of practiced ways of thinking and responding.

Much of Self-Will Happens in a Flicker

Suppose someone unfairly criticizes you.

You become defensive.

How long did that take?

Probably not very long.

You likely didn’t stop and consciously reason:

I don’t like what this person said. I am concerned about what other people may think. I predict that if I don’t respond immediately, they may believe it. Therefore, I have decided that defending myself is the best course of action.

It happened in a flicker.

Why?

Because you have done it before.

The thinking behind the response has been practiced so many times that the response may no longer require conscious deliberation. It has become part of the way you naturally respond.

This is one way self-will operates.

Self-will is not merely stubbornly saying, I want my way.

It is the familiar system through which we use what we think, feel, want, fear, know, and predict to determine what seems best and then direct ourselves toward that outcome.

Sometimes self-will produces obviously sinful behavior. At other times, it can sound completely reasonable.

That is one reason it can be so difficult to recognize.

Temptation Begins Closer to Home Than We May Think

James gives us an important description of temptation:

“But each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin…” — James 1:14–15 (ESV)

Notice where James directs our attention:

“his own desire.”

Something in me wants.

The Tenth Commandment addressed this internal problem long before the outward act:

“You shall not covet…” — Exodus 20:17 (ESV)

Coveting is more than wanting your neighbor’s possessions. It exposes the problem of wanting what I do not have.

That wanting can become the motivation behind envy, jealousy, lust, stealing, adultery, manipulation, dishonesty, resentment, and many other behaviors.

When something stands between Self and what Self wants, discomfort appears.

Then the familiar mechanisms can go to work.

How can I get what I want?

How can I avoid the cost?

How can I make this discomfort stop?

As adults, we usually don’t consciously ask those questions. The process can happen in a flicker because we have spent years practicing it.

Knowing something is wrong does not necessarily make the desire—or the practiced response to it—disappear.

The Problem Isn’t That You Think

Proverbs 3:5–6 gives us an alternative:

“Trust in the LORD with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.” — Proverbs 3:5–6 (ESV)

Notice what it does not say.

It doesn’t say, Don’t think.

Scripture repeatedly encourages wisdom, knowledge, understanding, and good judgment.

The problem isn’t having your own understanding.

The problem is leaning on it.

You can think, plan, learn from experience, seek wise counsel, gather information, and consider consequences. You should.

But there is something your understanding can never do.

It cannot know the future.

You can predict what will happen. You can make a very educated prediction. You can even be right most of the time.

But until the outcome actually occurs, you don’t know. And when circumstances begin pointing toward an outcome you don’t want, self-will often goes back to work trying to change it.

Self-will takes what it believes will happen and begins directing life toward the outcome it believes is best.

Trusting God means something different.

I use the understanding I have been given, but I don’t make it my final authority. I seek God’s direction and trust Him with an outcome I cannot know.

Faith says, I can trust God with the outcome.

Wisdom says, Don’t be foolish.

Those are not opposites.

I still think. I still plan. I still seek wisdom. But I no longer have to pretend that my best prediction of tomorrow is knowledge of tomorrow.

Knowing a Biblical Principle Is Not the Same as Practicing It

This is where many Christians become frustrated.

You know anger is wrong.

You know you should forgive.

You know you should tell the truth.

You know you should trust God.

You know you should be patient.

But knowing a principle and practicing a principle are not the same thing.

James makes that distinction plainly:

“But be doers of the word, and not hearers only, deceiving yourselves.” — James 1:22 (ESV)

A person can study forgiveness while continuing to use resentment.

A person can pray for patience while continuing to be impatient.

A person can read Scripture about trusting God while continuing to seek control.

A person can ask God for courage while repeatedly practicing avoidance whenever something becomes uncomfortable.

A person can know the importance of humility while continuing to practice defensiveness and self-justification.

That leads to a question Christians may not ask often enough:

What have I practiced as part of my self-will to make life turn out the way I believe it should?

Because what you repeatedly practice matters.

Principles are practiced, good and bad ones. Practices become habits. Habits become character.

Scripture even connects practice with developing discernment. Hebrews describes mature believers as:

“those who have their powers of discernment trained by constant practice to distinguish good from evil.” — Hebrews 5:14 (ESV)

Notice the words:

“trained by constant practice.”

Christian character development requires our participation.

That is why you can sincerely decide Sunday morning that you will respond differently and find yourself doing the same thing Tuesday afternoon before you have really thought about it.

Tuesday’s response may have been practiced for twenty years.

Conviction Is Not the Same as Character Change

The Holy Spirit’s conviction is enormously important.

You may now recognize things in yourself that once seemed perfectly normal. Something you once justified now troubles you. A response you once blamed entirely on somebody else you can now recognize as your responsibility.

That matters.

The struggle itself does not necessarily mean nothing happened when you became a Christian. Part of what has changed may be that you can now recognize a conflict that you previously justified or never saw.

But conviction does not automatically produce changed character.

God’s direction still calls for our participation.

Isaiah describes God’s direction this way:

“And your ears shall hear a word behind you, saying, ‘This is the way, walk in it,’ when you turn to the right or when you turn to the left.” — Isaiah 30:21 (ESV)

There are two parts there.

This is the way.

And:

Walk in it.

The direction comes from God.

The walking requires your participation.

Paul expresses something similar when speaking directly about life in the Spirit:

“If we live by the Spirit, let us also keep in step with the Spirit.” — Galatians 5:25 (ESV)

The Christian life is not simply waiting for God to remove every desire, thought, temptation, or practiced response that conflicts with His will.

When you recognize God’s way, you walk in it.

Then you walk in it again.

That is participation with God’s direction.

The Bag of Tricks and the Toolbox

Think of your established responses as your bag of tricks, accumulated over your lifetime.

When something threatens you, perhaps you reach for defensiveness.

When you don’t get your way, perhaps you reach for anger.

When you anticipate discomfort, perhaps you reach for avoidance.

When you’re wrong, perhaps you reach for justification.

When you want a particular outcome, perhaps you reach for control or manipulation.

Those things are familiar. You know how to use them. Some come out almost automatically because you have practiced using them for years.

Christian character development does not make your bag of tricks disappear.

Paul makes that point clear in Romans 7:

“So I find it to be a law that when I want to do right, evil lies close at hand.” — Romans 7:21 (ESV)

The old response remains available.

The difference is that you deliberately begin building a toolbox filled with biblical principles and learn to reach into it instead.

Instead of defensiveness, use honest examination.

Instead of resentment, practice forgiveness.

Instead of avoidance, practice courage.

Instead of manipulation, practice honesty.

Instead of blaming, practice responsibility.

Instead of pride, practice humility.

Instead of demanding a particular outcome, practice trusting God.

At first, reaching into the toolbox may feel unnatural.

Of course it does.

You are much better at using the tools in your old bag of tricks.

Sometimes you will reach into that old bag before you even recognize what you have done. Sometimes you will recognize what is happening and still choose the old response.

But increasingly, you can learn to stop, recognize God’s direction, and deliberately reach into your toolbox instead.

The goal is not to make the bag of tricks disappear.

The goal is to deliberately build out your toolbox and practice using what is in it.

At first, you may have to consciously remind yourself which tool to use. But as you repeatedly practice the biblical principle, it becomes more familiar.

Practice becomes habit, and habit becomes character.

Eventually, you become better at reaching for the toolbox. The old bag is still there, but you don’t have to keep pulling from it.

That is Christian character development.

This Is How We Participate With the Holy Spirit

This is not the whole story of the Holy Spirit’s work in a Christian. But it is an important part of our role with Him in developing Christian maturity.

The Holy Spirit convicts and guides.

“This is the way.”

We recognize the direction and participate:

“Walk in it.”

We deliberately reach for the biblical principle rather than the familiar mechanism of self-will.

Then we practice it.

Scripture tells us that something happens through that practice.

Our discernment becomes “trained by constant practice.”

We become increasingly able to recognize God’s direction and increasingly practiced at walking according to it.

The Holy Spirit has not become more powerful. God has not suddenly become more willing to guide us.

We have become more practiced at recognizing His direction and participating with it.

That is one way the Holy Spirit develops Christian maturity in us. He guides and convicts; we participate by walking in that direction and practicing what God has shown us. Over time, those practiced biblical principles become increasingly characteristic of the way we think and live.

This Is Participation, Not Earning Salvation

This distinction is important.

You don’t practice biblical principles to make God save you.

You don’t develop Christian character so Christ will finally accept you.

You don’t earn God’s grace by becoming better behaved.

You participate in character development because God has already begun something new in you.

Prayer matters.

Bible study matters.

Church matters.

Worship matters.

Christian fellowship matters.

But none of those eliminates the biblical instruction to do what you are learning.

You can hear about forgiveness repeatedly. Eventually, someone still has to be forgiven.

You can study patience. Eventually, patience has to be practiced when you would rather not wait.

You can pray for courage. Eventually, you have to walk toward something uncomfortable.

You can learn about trusting God. Eventually, you must face an outcome you cannot control and trust Him with it.

The more you actually practice God’s principles, the more meaningful prayer, Scripture, worship, teaching, and fellowship can become because they increasingly become part of the way you think and live.

So Why Do I Keep Sinning?

Because becoming a Christian did not erase the ways of thinking and responding that you spent a lifetime developing.

Self still wants.

Self still fears.

Self still seeks comfort.

Self still predicts outcomes.

Self still wants to protect itself, justify itself, and get its way.

And many of those mechanisms have been practiced so thoroughly that they can operate almost instantly.

But that is not the whole story anymore.

God’s Spirit is at work.

You can experience conviction where there was once justification. You can increasingly recognize the difference between leaning on your own understanding and following God’s direction.

And when you recognize that direction, you can participate by doing exactly what Scripture says:

“This is the way, walk in it.”

Walk in it once.

Then again.

And again.

Paul did not describe himself as someone who had already completed that process. Near the end of his ministry, he wrote:

“Not that I have already obtained this or am already perfect, but I press on to make it my own…” — Philippians 3:12 (ESV)

Then he described himself as “straining forward to what lies ahead” and pressing toward the goal (Philippians 3:13–14).

Paul began Romans 7 describing the painful reality:

I do what I don’t want to do.

Yet his response wasn’t:

Then salvation must not have happened for me.

Nor was it:

I’m saved, my sins have been forgiven, so it doesn’t matter.

He continued pressing forward.

You will not develop Christian character overnight. You may sometimes recognize self-will only after you have already acted on it. Later, you may recognize it while it is happening. Eventually, you may begin recognizing it before you act.

That is growth.

The goal isn’t simply to become better at feeling guilty about the same behavior.

The goal is to learn another way to live.

So the next time you find yourself asking, Why did I do that again?, don’t stop with condemnation.

Examine what happened.

What did I want?

What was I trying to avoid?

What outcome was I trying to control?

What principle did I just practice?

And then ask one more question:

What biblical principle can I practice instead?

When God shows you the way, walk in it.

Then walk in it again.

You will still have your old bag of tricks. Self-will will still offer its familiar answers. Paul tells us that even when we want to do right, evil remains close at hand.

But now you know what is happening.

You don’t have to automatically reach for what you have always practiced. You can recognize the old response, listen for God’s direction, reach into the toolbox you are deliberately building, and practice the biblical principle instead.

Sometimes you will get it right. Sometimes you won’t. When you don’t, recognize it, confess it, learn from it, and keep walking.

Because Christian maturity is not developed by simply knowing the way.

It is developed by walking in it.

One principle practiced. One different response. One step at a time.
