Can You Love Jesus and Still Live Like the World?

Have you ever seen someone who knows Jesus, knows the Bible, has been in church for years — and is still sinning?

You watch him disobey commandment after commandment, and something in you starts thinking: he’s probably just a namesake believer. He probably doesn’t have the Holy Spirit. He’s not actually saved. He might even go to hell.

Many of us have thought this, including me.

So why not actually see what Scripture says about it?

Even the Godliest People Still Sin

The Bible doesn’t divide humanity into people who sin and people who don’t.

All means all.

John goes even further:

So when we look at another believer’s life, we are not standing outside the problem looking in. We are sinners too.

That doesn’t make sin unimportant. It means we should be careful about using someone else’s sin as proof that they cannot possibly belong to Christ.

The Bible itself gives us some uncomfortable examples.

David is called “a man after God’s own heart” (1 Samuel 13:14). He is also the man who committed adultery with Bathsheba and then arranged for her husband to be killed.

Solomon received wisdom directly from God, wiser than anyone before or after him. In his old age, his foreign wives “turned away his heart after other gods,” and he built altars to idols (1 Kings 11:4).

Peter walked with Jesus for three years — and still denied even knowing Him, three times, with cursing (Matthew 26:74).

A person’s relationship with God does not make him incapable of falling into serious sin.

That should make us slow down before looking at another believer and concluding, “He can’t possibly be a real Christian.”

Don’t Turn Your Growth Into a Measuring Stick

Sometimes the more seriously we take our own faith, the easier it becomes to look down on people who aren’t where we are.

We pray more. We read the Bible more. We stop certain habits. We become more involved in church.

And slowly, without realising it, our obedience becomes a measuring stick.

Jesus told a story about exactly this. Luke tells us who He was aiming at:

Two men went up to the temple to pray. One was a Pharisee, the other a tax collector.

The Pharisees were the most religious people in Israel. They fasted, gave away a tenth of everything, studied the Scriptures, and kept the law carefully. If anyone in that crowd looked like good men, they did.

Tax collectors worked for Rome, taking money from their own people. Most took more than they were owed and kept the difference. They were seen as traitors and thieves.

The Pharisee prayed like this:

The tax collector wouldn’t even lift his eyes toward heaven. He simply prayed:

Jesus said it was the tax collector who went home justified (Luke 18:14).

Now the word justified comes from the courtroom. In the Old Testament it is what a judge does:

To be justified is to have the judge declare you not guilty. It is a verdict, not a description of your character.

But a judge does not acquit someone who is still lying about what they did. The tax collector told the truth about himself and asked for mercy.

That is repentance. And Scripture says it is required:

To repent is to turn. To change direction.

But turning is not the same as arriving. A person can turn toward God and still stumble, and that is what the rest of this article is about. What God will not accept is someone who wants forgiveness while still holding on to the sin and calling it fine.

Now look at what each man brought. The Pharisee brought his record. The tax collector brought the truth about himself, and asked for mercy.

And the verdict was not the end of his story. God does not declare people right so they can stay as they are. He begins to change them.

The Pharisee’s problem was not that he had done nothing right. It was that he used his own record to measure someone else’s standing before God.

It is possible to become so focused on another person’s failure that we forget our own need for mercy.

When You Believe, You Receive the Spirit

We know that salvation comes through believing in Jesus. It is not something we earn:

But there is something else Scripture tells us about believing in Jesus. When you believe, you receive the Holy Spirit.

Paul asks the Galatians a simple question:

Think about what Paul is asking. Did they receive the Spirit because they had followed the law well enough? No. They received the Spirit by hearing and believing.

Paul says the same thing to the Ephesians:

Notice the order: when you believed, you were marked with a seal.

You don’t first become a perfect Christian and then receive the Holy Spirit as a reward. The Spirit is God’s gift to those who believe in Christ.

There is a story in Acts that shows this plainly.

A man named Simon watched the apostles lay their hands on people, and he saw the Holy Spirit being given to them. He wanted that ability for himself, so he offered the apostles money.

Peter’s response was blunt:

Peter called it the gift of God.

And that’s important. A gift is not something you buy. It is not something you earn. You don’t have to get your life completely cleaned up first and then qualify for it.

The Holy Spirit is given by God.

Paul makes the connection between belonging to Christ and having His Spirit very clear:

So the Holy Spirit is not something reserved for a later stage of Christianity. He is not a reward for Christians who have become spiritually mature enough.

If you belong to Christ, you have His Spirit.

The Spirit Within You, Not Just Upon You

In the Old Testament, the Spirit usually came upon someone for a specific task. And often, it was about what that person would do for others rather than what the Spirit would do in that person.

The Spirit came upon Samson and gave him strength to deliver Israel (Judges 14:6). He came upon Bezalel and gave him the skill to build the tabernacle (Exodus 31:3). He came upon Saul to help him lead (1 Samuel 10:10).

And the Spirit could leave.

Samson didn’t even realise it had happened:

He got up expecting things to be just as they had always been. But they weren’t.

With Saul, Scripture simply says:

That was the Spirit upon a person, given for a particular purpose.

But God had already promised that something different was coming. Through the prophet Ezekiel, God said:

Notice the connection: a new heart, God’s Spirit within, and a changed life.

Then Jesus came and made the promise even clearer:

Look at the difference.

He would be with them and in them. And Jesus said He would abide with them forever.

He comes to live within you. He is not only concerned with what you do; He is working in who you are becoming.

And that’s why Paul describes what happens to a person who is in Christ:

He begins making you into someone new.

Now, this does not mean the Spirit stopped coming upon people for particular moments. He still does.

Think about Peter again.

Fifty days earlier he had been standing by a fire in a courtyard. A servant girl asked if he knew Jesus, and he said no. He said it three times, and the last time he swore about it. Then he went outside and wept.

Then came Pentecost, and the Holy Spirit came upon them.

Peter stood up in front of a crowd in Jerusalem. This was the same city where Jesus had been killed a few weeks before, in front of people who had been there when it happened. And he told them plainly that they had crucified the Messiah.

Nobody talked him into it. He had not prepared a sermon. He simply stood up and spoke.

Three thousand people.

The same man who could not admit to a servant girl that he knew Jesus now preached to thousands and did not flinch.

That is what it looks like when the Spirit comes upon someone. God gives a person what they need for the thing in front of them.

So there are two things here, and it helps to keep them apart. The Spirit living in you is permanent — He came when you believed, and He is not going anywhere. The Spirit coming upon you is God giving you what you need in a moment: courage, words, strength.

Does Sin Make the Holy Spirit Leave?

We already said it earlier. Every one of us sins. Not one person is sinless.

So think about it. If sin made the Holy Spirit leave, then no one would keep Him, because everyone sins. You would lose Him the same day you got Him.

That can’t be right. So what does sin actually do?

Paul tells believers:

Notice the language. He doesn’t say, “Do not make the Holy Spirit leave.” He says, “Do not grieve the Holy Spirit.” And he says it to Christians.

And look at what he calls them in the very same sentence. Sealed.

A seal was a mark of ownership. You sealed something to show it belonged to you and was not to be tampered with. Paul says that is what the Spirit is — God’s mark on a person, kept “for the day of redemption.”

So in one sentence Paul says both things. You can grieve Him. And you are sealed by Him.

Paul says something similar to the Corinthians, and that church was in a bad state. There were divisions among them (1 Corinthians 1:11). Believers were taking each other to court (1 Corinthians 6:6). There was sexual immorality that shocked even the people outside the church (1 Corinthians 5:1). And they were getting drunk at the Lord’s Supper (1 Corinthians 11:21).

Yet Paul still says:

Then he says it again, but this time about each person on their own:

Not just the church together. Your own body.

And notice where Paul says this. He is in the middle of warning them about sexual immorality. He is speaking to people who were sinning in exactly that way, and he tells them their bodies are the temple of the Holy Spirit.

He does not say the Spirit has left them. He says the opposite. The Spirit is in you, so think about what you are doing with your body.

That is the whole point. The Spirit staying is not a reason to take sin lightly. It is the reason sin matters.

So both things are true. Having the Holy Spirit does not mean a Christian will never sin.

So Why Does a Believer Keep on Sinning?

If the Holy Spirit really lives in someone, why doesn’t obedience just happen automatically?

Because God has given you a new heart, but you are still living in a body that hasn’t yet been redeemed.

To redeem something means to buy it back. In Israel, if a man fell into debt and had to sell himself into slavery, a close relative could pay the price and set him free (Leviticus 25:47-49). That relative was called his redeemer.

Christ has already paid for us. But the body you are living in has not yet been made new. That part is still to come.

Think about a newborn baby. It doesn’t start running on the first day or speaking in full sentences. First it learns to hold its head up, then to sit, crawl, stand, and eventually walk and run. No one expects a baby to know everything right away. It needs time, teaching, and practice to grow.

Our walk with God is much the same. When we first come to Christ, we don’t suddenly know everything or become spiritually mature overnight. We need time to learn God’s Word, grow in faith, make mistakes, and keep moving forward. Being a child of God and being mature in our faith are not the same thing.

That’s a real fight, and it is happening inside every believer.

Jesus said the same thing in Gethsemane. Hours before the cross, He took Peter, James and John further into the garden and asked them to stay awake with Him. They fell asleep. They wanted to stay awake. They couldn’t.

So a believer sinning again and again isn’t necessarily proof that nothing changed. It’s proof that the change is real but not yet finished. Paul says the body is still waiting:

If you sin and it still bothers you afterward — if you feel bad about it and can’t just brush it off — that’s actually a good sign. It means the fight is still going on inside you.

When We Stop Noticing

There is something that can happen when the same sin is repeated again and again without ever being dealt with.

Imagine someone moves into a house right beside a busy railway track. The first few nights, every passing train wakes him up. The noise is hard to ignore. But after a while, he gets used to it. A few weeks later, he barely notices the trains. Eventually, he can sleep right through them.

The trains haven’t become quieter. He has simply become used to the noise.

Our conscience can be like that. When we keep ignoring the warning inside us, we can become less sensitive to what once bothered us. The sin hasn’t become less serious. We’ve just become less bothered by it.

And it doesn’t usually happen all at once. It happens slowly — one choice at a time, one excuse at a time, until something we once knew was wrong starts to feel normal.

Paul describes exactly this:

Hebrews gives a similar warning:

Look at what Hebrews tells us to do about it. It doesn’t say try harder on your own. It says encourage one another daily.

That is what other Christians are for. Someone close enough to notice, and honest enough to say something.

But a hardening conscience doesn’t stay where it starts.

A person who keeps ignoring the warning inside them doesn’t usually announce that they have stopped believing. They just drift. Other things fill the space — work, money, comfort, whatever is in front of them. The Bible starts to feel less relevant. Prayer stops.

Then the doubts begin.

You look at people who don’t believe in Jesus at all, and their lives seem fine. Happier than yours, even. So you start to wonder whether any of it was ever true.

You see suffering that makes no sense, and you decide that a good God would not allow it.

And if you never learned the Bible properly to begin with, you have nothing to answer with. The doubts sound reasonable, and there is nothing inside you to push back.

Some people end up rejecting Christ altogether.

That is why this matters. It is a warning sign, not a small thing.

And if you are worried that this has happened to you, that worry is a good sign. Someone who has truly stopped caring does not lie awake worrying about it.

The Difference the Spirit Makes

Coming to Christ does not mean we will never sin again. We are still learning, still growing, and still fighting against old habits. The difference is that we are no longer alone in that struggle. The Holy Spirit is in us, and He begins to change the way we respond to sin.

We may fall into the same sin more than once. We may lose our temper, speak harshly, become jealous, lie, hold a grudge, or give in to temptation. But when the Holy Spirit brings it to our attention, we have a choice. We can listen, confess it to God, turn away from it, and ask Him to help us — or we can keep making excuses and push the conviction away.

The difference is not between a believer who sins and a believer who never sins. We all stumble. The difference is what happens after we stumble.

A believer who keeps listening to the Spirit will slowly begin to change. Maybe the anger that once lasted for hours now lasts only a few minutes. Maybe the person who used to hold a grudge for years begins learning to forgive. Maybe someone who used to lie without thinking now feels troubled inside and chooses to tell the truth.

Jesus used a picture for this:

A tree doesn’t announce what it is. It simply grows what is in it, and over time you can see.

Use that on yourself before you use it on anyone else.

And that is what Paul is describing here:

Fruit grows. It doesn’t appear overnight.

That is also why Paul says:

Notice he doesn’t say we will never struggle. He tells us to walk. Walking is something you keep doing.

We can fall and get back up. We can fail and ask God for forgiveness. We can struggle with the same weakness and still keep fighting it. The important thing is that we don’t make peace with our sin.

But What About Falling Away?

There are some warnings in the Bible that frighten people, and it is better to look at them than to leave them alone.

The strongest one is in Hebrews, and it is worth reading the whole passage instead of the warning on its own.

The writer had been telling his readers to stop staying beginners. He wanted them to grow up:

Then comes the warning:

That is serious, and it should not be softened.

But notice what it describes. Not a believer who sins. Someone who falls away — who knew Christ and then turned from Him. That is not “I failed again.” That is walking out.

Then the writer uses a picture. Land that drinks the rain and produces a useful crop is blessed. Land that produces thorns is worthless (Hebrews 6:7-8). What matters is not what the ground received. It is what grew.

And then he says this:

He had just given the hardest warning in the letter. And then he tells them he does not think it applies to them.

He was not saying they had fallen away. He was warning people he believed were safe, so that they would keep going:

The same thing happens later in the letter. Hebrews warns about those who “deliberately keep on sinning after we have received the knowledge of the truth” (Hebrews 10:26). Then, a few verses on:

Twice the writer gives a hard warning. And twice he follows it by telling his readers he does not believe they are those people.

That is what these warnings are for. Not to make believers live in fear, but to keep us walking.

So a Christian can stumble without abandoning Christ. The real danger is not falling down. It is deciding you no longer want Christ, and walking away.

So Will He Still Go to Heaven?

So, will a person who truly believes in Jesus and trusts in what He did for us go to heaven?

Yes. Salvation is through faith in Jesus Christ, not because we have lived a perfect life.

But this does not mean we can say, “I believe in Jesus, so I can live however I want.”

Real faith changes the way we live.

Think about a doctor telling you that something you are doing is seriously harming you. If you truly believe your doctor, you won’t simply say, “I believe you,” and then carry on exactly as before.

You may struggle to stop. You may even fall back into the same habit. But you will want to change, because you believe what the doctor told you.

The same is true of our faith in Jesus. If we truly believe that He died for our sins, rose again, and is Lord, that belief should begin to change us.

Paul asks the question directly:

We will still sin. We will still make mistakes. We may struggle with the same sin more than once. But we don’t want to stay down.

The question is not, “Have I become perfect?”

None of us has.

The question is, “Am I trusting Christ and allowing His Spirit to change me?”

Because genuine faith does not leave us exactly where it found us.

Conclusion

This article started with you watching someone else and wondering. So let’s finish there.

Don’t be quick to judge another believer or decide whether they are truly saved. Jesus warned us:

Before looking at someone else’s failures, look at your own heart. We all need the same grace, the same mercy, and the same Saviour.

Keep following Jesus, keep listening to the Holy Spirit, and let God do the work of changing you.
