The Connection Between the Heart and Healing

One of the most overlooked truths in Scripture is that many of life's greatest battles begin in the heart before they ever manifest in our attitudes, words, or actions. While we often focus on changing behavior, God focuses on transforming the heart because the heart is the source from which our lives flow.

Proverbs 4:23–24 (NKJV)

"Keep your heart with all diligence,
For out of it spring the issues of life.

Put away from you a deceitful mouth,
And put perverse lips far from you."

Notice the order. The Book of Proverbs first tells us to guard our hearts and immediately follows by telling us to guard our mouths. This is not accidental. There is a direct connection between what fills the heart and what comes out of the mouth.

Jesus taught the very same principle.

Matthew 12:34–35 (NKJV)

"...For out of the abundance of the heart the mouth speaks. A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things."

Your mouth is like a spiritual thermometer. It doesn't create what is inside; it simply reveals it.

If your conversations are continually filled with fear, bitterness, offense, criticism, doubt, or hopelessness, your words may be revealing a heart that has been wounded and needs healing.

Likewise, if your words are filled with faith, hope, forgiveness, and thanksgiving, they reveal a heart that is being transformed by God's Word.

The Bible repeatedly teaches that words have tremendous influence.

Proverbs 18:21 (NKJV)

"Death and life are in the power of the tongue,
And those who love it will eat its fruit."

Words are not empty sounds. They continually reinforce what we believe. Every time we agree with God's promises, our faith is strengthened. Every time we continually rehearse fear, defeat, or unbelief, we reinforce those strongholds within our hearts.

This is why Solomon warns us to put away a deceitful mouth and perverse lips.

The word perverse means twisted, distorted, or contrary to truth.

A perverse mouth is not limited to lying. It also speaks words that contradict what God has already declared.

God says, "I will never leave you."

A perverse mouth continually says, "I'm all alone."

God says, "By His stripes you were healed."

A perverse mouth continually says, "I'll probably never get better."

God says, "I know the plans I have for you."

A perverse mouth continually says, "Nothing good ever happens to me."

Eventually our words become an agreement either with God's promises or with our circumstances.

Another powerful verse reveals why so many people become discouraged.

Proverbs 13:12 (NKJV)

"Hope deferred makes the heart sick,
But when the desire comes, it is a tree of life."

Notice Solomon does not say hope deferred makes the body sick.

He says it makes the heart sick.

When hope is continually postponed, disappointment begins to settle into the heart.

Disappointment becomes discouragement.

Discouragement becomes unbelief.

Unbelief begins to shape our conversations.

Before long, we begin speaking exactly what our wounded hearts have accepted as truth.

This helps explain why Jesus continually ministered to people's hearts before addressing their physical conditions.

He restored hope.

He forgave sins.

He challenged unbelief.

He revealed the Father's love.

He built faith.

Healing and the condition of the heart were often connected.

When I minister to people, I often listen carefully before praying.

Within just a few minutes, people frequently reveal what they truly believe.

"I know God can heal, but..."

"I've prayed for years."

"I don't think God wants to heal me."

"This is probably just my cross to bear."

Those words reveal more than emotions.

They often reveal a heart that has become weary.

Scripture says,

Romans 10:17 (NKJV)

"So then faith comes by hearing, and hearing by the word of God."

If faith comes by hearing God's Word, unbelief often grows by continually hearing words of fear, defeat, and hopelessness.

Jesus addressed this very issue after the disciples failed to deliver a young boy.

Matthew 17:20 (NKJV)

"...Because of your unbelief..."

Notice Jesus identified unbelief before discussing power.

The issue was not that God lacked power.

The issue was what had settled into the heart.

Jesus also gave us a beautiful picture through the Pharisee and the tax collector.

Luke 18:13–14 (NKJV)

"And the tax collector, standing afar off, would not so much as raise his eyes to heaven, but beat his breast, saying, ‘God, be merciful to me a sinner!’

I tell you, this man went down to his house justified rather than the other…”

Now consider the condition of these two hearts.

The Pharisee was confident in himself.

The tax collector was confident in God’s mercy.

Suppose both men had also come needing physical healing.

Which one would have been more prepared to receive from God?

The tax collector.

Not because he deserved healing more.

Not because God loved him more.

But because humility leaves the heart open to receive.

Pride often convinces us we don’t need God.

Humility recognizes that He is our only hope.

James reinforces this principle.

James 4:6 (NKJV)

“God resists the proud,
But gives grace to the humble.”

Peter teaches the same truth.

1 Peter 5:6–7 (NKJV)

“Therefore humble yourselves under the mighty hand of God, that He may exalt you in due time,

casting all your care upon Him, for He cares for you.”

Notice that humility and casting our cares upon God are connected.

Many people continue carrying burdens God never intended them to carry.

Fear.

Offense.

Bitterness.

Unforgiveness.

Condemnation.

Anxiety.

Years of disappointment.

All of these can weigh heavily upon the heart.

Jesus invites us to release those burdens.

Matthew 11:28–30 (NKJV)

“Come to Me, all you who labor and are heavy laden, and I will give you rest.

Take My yoke upon you and learn from Me…

For My yoke is easy and My burden is light.”

Healing is never simply about the body.

Throughout the Gospels Jesus continually ministered to the whole person.

He restored hope.

He forgave sins.

He renewed minds.

He strengthened faith.

Then healing often followed.

Isaiah prophesied this centuries before Christ came.

Isaiah 53:4–5 (NKJV)

“Surely He has borne our griefs
And carried our sorrows…

But He was wounded for our transgressions…

And by His stripes we are healed.”

Peter confirms that promise.

1 Peter 2:24 (NKJV)

“…who Himself bore our sins in His own body on the tree… by whose stripes you were healed.”

Healing is part of Christ’s redemptive work.

The question is often not whether God is able.

The question becomes, what has my heart come to believe?

Many believers know God can heal.

Far fewer are convinced He is willing to heal them.

That uncertainty eventually appears in their words.

This is why Jesus asked people questions before performing miracles.

“Do you believe?”

“According to your faith let it be to you.”

“Only believe.”

Faith was continually being cultivated because faith grows in a heart filled with hope.

Paul reminds us where lasting transformation begins.

Romans 12:2 (NKJV)

“And do not be conformed to this world, but be transformed by the renewing of your mind…”

A renewed mind produces a renewed heart.

A renewed heart produces renewed words.

Renewed words strengthen faith.

Faith positions us to receive everything God has promised.

This is why we must become students of our own conversations.

Listen to yourself.

Are your words continually agreeing with God’s promises?

Or are they continually agreeing with your circumstances?

The heart and the mouth are always working together.

The mouth reveals the heart.

The heart directs the life.

The life reflects what we have continually believed.

Guard your heart with diligence.

Fill it with God’s Word.

Remove bitterness.

Release unforgiveness.

Restore hope.

Reject unbelief.

Put away a deceitful and perverse mouth.

Choose words that agree with God’s truth.

Because when hope is restored, faith begins to rise.

When faith rises, expectation returns.

And when expectation returns, we become better positioned to receive from the God who is both able and willing to fulfill every promise He has made.

Philippians 4:8 (NKJV)

“Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report… meditate on these things.”

Whatever fills your heart will eventually fill your mouth.

Whatever fills your mouth will continually shape your heart.

Guard both carefully, because out of the heart flow the issues of life.
