When God Gives You a New Heart

God Does Not Merely Change Your Circumstances—He Changes You From the Inside Out

Scripture References — Ezekiel 36:26–27 • 2 Corinthians 5:17

“I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in My statutes, and you will keep My judgments and do them.”

“Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.”

Introduction – The Problem Is Deeper Than Your Circumstances

There are some things in life that can be repaired. A broken window can be replaced. A damaged automobile can be rebuilt. A torn shirt can be sewn. Even a prison cell can be repainted until it looks almost new.

But there is something wrong with mankind that no amount of paint, education, discipline, religion, rehabilitation, or good intentions can repair.

The problem is the human heart.

That is what makes Ezekiel 36:26–27 such a powerful passage of Scripture. God does not promise merely to improve the old heart. He promises to give us a new one.

Ezekiel ministered during one of the darkest periods in Israel's history. Jerusalem had fallen. The temple had been devastated. Many of God's people had been carried into Babylonian captivity. Their circumstances were terrible—but their greatest problem was not Babylon.

Their greatest problem was their own rebellious hearts.

For generations Israel had resisted God, worshiped idols, rejected His commands, and dishonored His name. Judgment had finally come. Yet in the middle of this dark setting, God gave Ezekiel an extraordinary promise.

God said:

“I will give you a new heart.”

Notice who performs the miracle.

God says:

“I will give…”

“I will take…”

“I will put…”

“I will cause…”

The emphasis is on what GOD does.

Christianity is not primarily God telling sinful people to try harder. The gospel announces that God can do something within us that we could never accomplish ourselves.

He can change the heart.

Many incarcerated men understand the desire for a second chance. You may have wished a thousand times that you could go backward and change something you did. Perhaps one decision altered the course of your entire life. Perhaps anger, addiction, pride, greed, violence, lust, or foolishness brought consequences that cannot simply be erased.

You cannot rewrite yesterday.-- LIfe doesn’t provide do-overs

But God can transform the person who enters tomorrow.

Jesus Christ does not merely offer you a better version of your old life.

Through Him, God makes sinners new creations.

Christianity is not behavior modification because God’s purpose is not merely to make bad people behave better - It is heart transformation.

A person can change his habits, clean up his language, abandon certain sins, attend chapel, and become more disciplined while his heart remains far from God. The gospel goes deeper. God changes us from the inside out—giving new desires, new affections, a new attitude toward sin, and a growing desire to please Him.

Behavior modification says, “I must change what I do.” Heart transformation says, “God must change who I am.” And when God truly changes the heart, a changed life will increasingly follow.

And when God changes the heart, eventually the life begins to change with it.

Main Point #1– Our greatest problem is the heart

God says:

“I will take the heart of STONE out of your flesh.”

Why would God describe the human heart as stone?

Because stone is hard.

Stone does not respond.

Stone does not feel.

Stone resists pressure.

This is a picture of the natural heart of fallen mankind toward God.

Scripture repeatedly tells us that sin is much deeper than our outward behavior. Jesus taught that sinful actions proceed from within:

“For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.” —Matthew 15:19

We often concentrate on the fruit while God goes directly to the root.

A man may say:

“My problem was drugs.”

“My problem was alcohol.”

“My problem was anger.”

“My problem was the people I ran with.”

“My problem was money.”

“My problem was my environment.”

Those things may have played significant roles in someone's destruction. But Jesus takes us deeper.

Sin comes from a fallen heart.

That is why changing someone's surroundings alone cannot change the person.

A prisoner can be moved from one institution to another and carry the same heart with him.

A man can leave segregation and carry the same heart.

A man can finish a rehabilitation program and carry the same heart.

A man can even walk out through the prison gates and carry the same heart.

Unless something happens inside, the deepest problem remains.

John Calvin wrote that the human heart is, in effect, “a perpetual factory of idols.” We continually find something other than God to worship, trust, pursue, or obey.

This is why Christianity begins with repentance…..A genuine turning from sin and turning to God.

We stop blaming everyone else and acknowledge:

“Lord, the problem is also in me.”

David understood this after his terrible sin. He did not merely pray for improved circumstances. He cried:

“Create in me a clean heart, O God, and renew a steadfast spirit within me.” —Psalm 51:10

David knew he needed something only God could provide.

So do we.

The first step toward genuine spiritual transformation is recognizing that we do not merely need better circumstances.

We need God to change our hearts.

Main Point #2 – God does not polish the stone—He gives a new heart

God continues:

“I will give you a NEW heart and put a NEW spirit within you.”

This is one of the greatest promises in the Old Testament.

God does not say:

“I will educate your stone heart.”

“I will polish your stone heart.”

“I will make your stone heart religious.”

“I will teach your stone heart better manners.”

He says:

“I will give you a new heart.”

That is regeneration.

Jesus described this miracle to Nicodemus when He said:

“You must be born again.” —John 3:7

Nicodemus was religious, educated, respected, disciplined, and knowledgeable about Scripture.

Yet Jesus told him that religion was not enough.

He needed new life.

This is where Christianity differs radically from merely turning over a new leaf.

A man can change certain habits without having a changed heart.

He can become more disciplined.

He can stop using drugs.

He can control his temper.

He can attend chapel.

He can memorize Scripture.

He can learn Christian vocabulary.

All of those changes may be good, but none of them automatically means he has been born again.

The question is deeper:

Has Christ changed your heart?

Second Corinthians 5:17 declares:

“If anyone is in Christ, he is a NEW creation.”

Notice that Paul does not say that anyone in Christ becomes a slightly improved creation.

He says:

“New creation.”

New desires begin appearing.

Sin that once seemed harmless begins troubling your conscience.

The Bible that once seemed boring becomes precious.

Prayer becomes more than religious language.

You begin caring whether your life pleases God.

You begin grieving when you sin against Him.

You begin wanting Christ more than you once did.

Charles Spurgeon repeatedly emphasized that conversion is not merely outward reformation but a work of divine grace within the sinner.

That does not mean believers become instantly perfect.

They do not.

But something fundamental has changed.

There is now a battle where once there may have been surrender.

The regenerated man can still fall into sin, but he can no longer make peace with sin as though it were his rightful master.

God has given him a new heart.

Main Point #3 – God puts His Spirit within His people

Ezekiel's promise becomes even more remarkable:

“I will put My Spirit WITHIN you.”

God does not merely give His people instructions and then leave them alone to figure out how to obey Him.

He gives them His Spirit.

Think about that.

The Holy Spirit of God dwells within those who belong to Christ.

This means the Christian life cannot be lived merely through human determination.

There are temptations stronger than your willpower.

There are habits deeper than your resolutions.

There are wounds you cannot heal yourself.

There are desires you cannot conquer merely by saying, “Tomorrow I will try harder.”

You need divine power.

God gives His Spirit.

The Holy Spirit convicts us of sin, illuminates God's Word, produces spiritual fruit, strengthens us against temptation, comforts us in suffering, and increasingly conforms believers to Christ.

Paul writes:

“Walk in the Spirit, and you shall not fulfill the lust of the flesh.” —Galatians 5:16

That truth is enormously important inside prison.

You may live around anger every day.

You may hear profanity constantly.

You may encounter temptation, racial tension, intimidation, manipulation, pornography, drugs, violence, gossip, and pressure to compromise.

You cannot always control what happens around you.

But through God's Spirit, what happens around you does not have to control what happens within you.

R.C. Sproul often emphasized that genuine regeneration is the sovereign work of the Holy Spirit. Christianity therefore rests not merely on human determination but upon God's transforming grace.

The believer still must resist temptation.

He still must pray.

He still must study Scripture.

He still must put sin to death.

He still must make difficult choices.

But he does not fight alone.

The same God who commands holiness provides His Spirit to enable His children to pursue holiness.

When you feel weak, remember Ezekiel's promise:

“I will put My Spirit within you.”

Your strength is insufficient.

God's is not.

Main Point #4 – A changed heart produces a changed walk

God says:

“I will put My Spirit within you and CAUSE you to walk in My statutes.”

Notice the connection.

New heart.

New spirit.

God's Spirit.

Then:

A new walk.

The order matters.

God changes us inwardly, and that inward transformation increasingly becomes visible outwardly.

A profession of faith without any concern for obedience should cause serious self-examination.

Jesus said:

“If you love Me, keep My commandments.” —John 14:15

Obedience does not purchase salvation.

We are saved by Grace!

But the grace that saves us begins TRANSFORMING us.

John MacArthur has often stressed that genuine saving faith produces spiritual fruit. Good works are not the cause of salvation, but they are evidence that God's transforming work is present.

This is especially important in prison ministry.

It is possible to learn how to sound Christian without learning how to live as one.

You can carry a Bible.

You can attend chapel.

You can quote Scripture.

You can discuss theology.

You can say “Praise the Lord.”

But what happens when somebody disrespects you?

What happens when someone owes you something?

What happens when temptation comes?

What happens when nobody is watching?

What happens when forgiving someone costs you something?

That is where the changed heart begins revealing itself.

Thomas Brooks wrote extensively about the danger of cherishing secret sin while maintaining outward religion. Genuine grace produces an increasing desire to deal seriously with sin.

Not perfection.

But direction.

Ask yourself:

Am I moving toward Christ?

Is sin becoming more hateful to me?

Is obedience becoming more important?

Am I quicker to repent?

Am I learning to forgive?

Is my speech changing?

Are my private thoughts changing?

A changed heart eventually produces a changed walk.

Prison Application

You may be reading this devotional behind a steel door.

Perhaps you have decades remaining on your sentence.

Perhaps you have life without parole.

Perhaps you are approaching a parole hearing.

Perhaps you may never physically leave prison.

Ezekiel 36:26–27 contains wonderful news for every one of those situations:

God can transform a person anywhere.

There is no prison wall thick enough to stop the Holy Spirit.

There is no security level high enough to keep Christ out.

There is no criminal history too long for the grace of God.

And there is no heart so hardened that God cannot replace it.

Perhaps years of incarceration have hardened you.

You learned not to trust.

Not to cry.

Not to show weakness.

Not to forgive.

Maybe bitterness has become armor around your heart.

But the same God who said,

“I will take the heart of stone”.......

can still do exactly that.

Do not merely ask God to change your housing.

Do not merely ask Him to change your sentence.

Do not merely ask Him to change your cellmate.

Do not merely ask Him to change the officers.

Do not merely ask Him to change your circumstances.

Pray:

“Lord, change me.”

Ask Him to expose bitterness.

Ask Him to expose lust.

Ask Him to expose pride.

Ask Him to expose unforgiveness.

Ask Him to expose hypocrisy.

Ask Him to expose secret sin.

Then bring those things honestly before Christ.

Your prison identification number does not define your spiritual identity.

Your crime does not have to write the final chapter of your life.

Your worst decision does not possess greater power than the blood of Jesus Christ.

You may not be able to change where you sleep tonight.

But God can change the man who wakes up there tomorrow morning.

Final Thought – When God Changes the Heart, He Changes the Life

Ezekiel 36:26–27 is ultimately a passage about God doing what sinners cannot do for themselves.

We cannot perform spiritual heart surgery upon ourselves.

But GOD can.

He removes the stone.

He gives the new heart.

He gives the new spirit.

He puts His Spirit within His people.

And He begins producing a new walk.

Billy Graham often proclaimed the necessity of the new birth because Christianity is not merely accepting a philosophy or adopting a moral code. Christ comes to transform lives.

Maybe you have spent years trying to become a better version of the old you.

There is something infinitely greater available in Jesus Christ.

New life.

Maybe people still remember who you used to be.

Maybe your paperwork describes the worst thing you ever did.

Maybe someone has already decided that you will never change.

God is not limited by anyone's opinion of you.

Look again at His promise:

“I will give you a new heart.”

That is hope.

Not because you are strong enough.

Not because you deserve another chance.

Not because you can repair everything you have broken.

But because God is merciful enough to make sinners new.

Bring Him the stone.

He can give you a heart of flesh.

Bring Him your rebellion.

Bring Him your sin.

Bring Him your failures.

Bring Him the years you cannot recover.

Come to Christ in repentance and faith.

And then spend whatever years God gives you demonstrating what His grace can do with a surrendered life.

You may still have the same name.

You may still have the same number.

You may still wake up in the same cell.

But when God gives you a new heart, you are no longer the same man.

Reflection Questions

1. What does the “heart of stone” in Ezekiel 36:26 teach me about the seriousness of sin?

2. Have I experienced genuine heart transformation, or have I primarily changed outward behavior?

3. What areas of my heart have become hardened through anger, disappointment, suffering, or incarceration?

4. Is there a particular sin the Holy Spirit has been convicting me to confess and forsake?

5. What evidence can I see that God is changing my desires, attitudes, words, and actions?

6. How can I depend more upon the Holy Spirit instead of relying only upon my own willpower?

7. If someone watched my life closely for the next thirty days, what evidence would they see that Jesus Christ is changing my heart?

Closing Prayer

Father, 

I cannot change my own heart. I need Your grace. Remove everything within me that is hardened against You.

Give me a clean heart and a steadfast spirit. Forgive my sins through Jesus Christ, and fill me with Your Holy Spirit.

 Change my desires, my thoughts, my words, and my actions. Teach me to walk in obedience, not to earn Your love, but because You have shown me mercy.

Make my life living evidence that Jesus Christ still changes sinners from the inside out. In Jesus' name, Amen.
