The Spiritual Power of Words: How What You Say Affects Your Ability to Heal

Your voice matters so much more than you know. It’s not about the volume of your words, but the weight they carry in the spirit.

The words you speak affect your overall wellness.

Did you know the world wasn’t created from visible substance?

It was made by the voice of God.

By faith we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible. (Hebrews 11:3)

So now, in 2026, how can we expect to fully heal ourselves physically, mentally, and spiritually only from things that are visible?

Hebrews 11:3 unveils another crucial tidbit: the words we speak matter, too.

Because God spoke the universe into existence.

Words hold serious weight.

Modern neuroscience research observes the same thing, but the Bible said it first.

And God said, “Let there be light,” and there was light. And God saw that the light was good. (Genesis 1:3-4)

We may not be God, but we were made in His image.

Our words count. And we should take that seriously.

In the beginning was the Word, and the Word was with God, and the Word was God. (John 1:1)

And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. (John 1:14)

When Jesus fasted 40 days in the desert, the enemy saw it as the perfect opportunity to deviously temp Jesus.

The devil’s first order of attack was commanding a hungry, tired Jesus to speak to a collection of rocks and turn them into bread.

The enemy is after our words and what we speak!

But God.

Everything always draws back to God and His mighty power.

Jesus rebuttaled the enemy with the word of God.

Because words are powerful. Especially the words written in the great book.

Be gone, Satan! For it is written,“‘You shall worship the Lord your God and him only shall you serve.’” Then the devil left him, and behold, angels came and were ministering to him. (Matthew 4:10-11)

For with the heart one believes and is justified, and with the mouth one confesses and is saved. (Romans 10:10)

When we confess with our lips, we are saved by the grace of God.

Speaking aloud publicly declares before men our beliefs. Decree these verses over your life and watch it transform:

No weapon formed against me shall prosper. (Isaiah 54:17)

I overcome by the blood of the lamb. (Revelation 12:11)

He prepares a table before me in the present of my enemies; you anoint my head with oil; my cup overflows. (Psalm 23:5)

The God of hope fills me with all joy and peace in believing, so that by the power of the Holy Spirit I abound in hope. (Romans 15:13)

I am a new creation; the old has gone, the new has come! (2 Corinthians 5:17)

I can do all things through Christ who strengthens me. (Philippians 4:13)

A Matter of Life and Death

“…for by your words you will be justified, and by your words you will be condemned.” (Matthew 12:37)

Proverbs 18:21 further expounds on the power of our words.

There is not an in-between. Our words either impart life, or breed death. They either feed into the kingdom of light, or cater to the kingdom of darkness.

The best example is found in our own origin story.

God spoke us into existence. He spoke life over us. (Genesis 1:26)

But just as quickly, Satan spoke death over us. (Genesis 3:4)

“You surely will not die.”

This is the lie the enemy spoke to Adam and Eve.

Satan’s manipulative twisting of words provoked Adam and Eve to break faith.

It was a quick word.

And resulted in a quick action!

Adam and Eve’s response swiftly morphed God’s good, immortal creation into sinful, mortal beings.

Words propel action.

And when words stem from negative intention, it breeds negative action.

What The World Says Today

Modern culture harps on positive vibes and daily mantras.

Coupled with the New Age concept of manifestation, which is based on newfound psychology research, the modern world is fully aware of the power of words, beliefs, and mindset.

Psychoneuroimmunology in particular studies the connection between the central nervous system and the immune system.

But yet, there is nothing new about this information.

It was written into the word of God from the beginning.

Good Fruits Equal Good Speech

In Proverbs 18:21 it says our words are so powerful that speaking positive words of gratitude leads to reaping positive fruits.

But negative words breed negative fruits.

Ephesians 5:9 provides us with a catalog of the positive spiritual fruits: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

These are the fruits of the spirit of God.

Exuding good fruits glorifies God. He wants to give us the best life, and this can happen when our words match our fruit.

The negative fruits however, are of the flesh: enmity, strife, jealousy, fits of anger, rivalries, divisions, envy, drunkenness, sexual immorality, idolatry, impurity…

It comes down to the fruits of the spirit versus the fruits of the flesh.

When we sow into our carnal desire, we reap carnal results. When we sow into the spirit, we reap the rewards of the spirit.

“For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life.” (Galatians 6:8)

When we speak pessimistically over our life or the lives of others, with any level of defilement [sowing to the things of the flesh], we fall into polluted thinking that seeps throughout the physical body, inevitably contaminating our whole life.

So also the tongue is a small member, yet it boasts of great things. How great a forest is set ablaze by such a small fire! (James 3:5)

Words burn. Whether they burns slow or fast, the outcome’s the same: ultimate destruction.

“And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life,[a] and set on fire by hell.” (James 3:6)

This is why many remain stuck in negative thinking, in a body full of aches and pains. They keep repeating to themselves that this is their reality.

It is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.” (Matthew 15:11)

Wow. This shuts down the notion that solely eating well and taking care of your health will heal you completely.

Jesus is not saying here that you shouldn’t be concerned with eating well or taking care of your body.

Instead, Jesus is explaining that it’s all about what’s in the heart. Because our hearts truly determine how impure we are.

We speak from the heart, and if our heart is tainted with hate, disgust, strife, jealousy, anger, lust, or double-mindedness, there’s a good chance that is exactly what will be spilling into our bodies and what will be spewing out to the rest of the world!

I once contacted a pastor in a moment of sheer panic.

I was a new Christian back then and concerned with the soul of someone I loved.

“Well, does he think he’s a good person?” The pastor asked sternly.

“I mean…”

He didn’t wait for me to finish.

“Because anyone who thinks they’re a good person won’t care to know Jesus.”

Ouch. I was floored. And a little in denial. I didn’t want this to be true. After all, how many people out there consider themselves a good person?

I had to implore further.

God, is this is really true? And can this apply to those who call themselves Christian, too?

As per usual, Scripture has answers.

The Pharisee Mindset

Jesus says He did not call the righteous, but sinners to repentance. (Luke 5:32)

Jesus was speaking straight to the Pharisees, the religious people of His time.

In that moment, Jesus and His disciples were dining with tax collectors, some of the most reputed sinners of the entire village.

The Pharisees were complaining about Jesus associating with the biblical IRS. And at first, you can’t blame them.

But Jesus clapped back.

“It is not the healthy who need a doctor, but the sick. But go and learn what this means: ‘I desire mercy, not sacrifice.’ For I have not come to call the righteous, but sinners.” Matthew 9:10–13

God does not call those who think they are already in righteous standing because of their own works and conduct.

And that’s what the Pharisees were. They thought they were justified by appearing outwardly good. By following rules and deflecting all ethical heat off them and pointing it elsewhere.

Jesus calls the Pharisees whitewashed tombs (Matthew 23:27).

Did you catch that? Beautifully painted on the outside but containing dead bones and impurities on the inside.

The outwardly religious people in Jesus’ day were spiritually dead, and so are the modern-day counterparts.

The Pharisee mindset will have you thinking you’re a prison convict who can just get out on good behavior.

Not so fast.

An outward demonstration does not lead to an inner transformation.

Many are called, but few are chosen. (Matthew 22:14)

If we think we are a good person in our own right, we won’t accept the call.

And if we don’t answer Jesus when He calls, He certainly can’t choose us!

“God resists the proud, but gives grace to the humble.” (James 4:5)

Sadly, this doesn’t just limit non-believers uninterested in having a relationship with Jesus.

Many believers, myself included, can become haughty and fluffed up from our own works and pride. When this happens, it becomes easy to omit Jesus from the picture altogether.

Being proud for partaking in manmade rituals and religious traditions and itching to always be right in theological debates amplify this.

Churchianity

It’s easy to identify solely in our affiliated denomination or religious sect.

And just as much to to harp on our own religious works or Bible knowledge.

But this is dangerous territory to operate in.

This is exactly how the Pharisees got down. They were proud of their own rules and works and social standing and loved to point fingers at everybody else.

This is works-based salvation, and it is not of God.

In fact, our works are filthy rags to God! (Isaiah 64:6)

Which is, of course, part of the good news. We cannot measure up to immaculate perfection in our fallen human state.

But God!

God overtook our mess. Covering us through the blood of the Lamb. Covering us through our savior Jesus Christ. All our sin and shortcomings are fully atoned by the sacrificial healer.

Phew!

Can you imagine if we had to clean up this filthy mess of sin all on our own?

Which is a big part of the whole coming to Jesus thing. If we don’t recognize the mess of sin we’re waist deep in, we won’t acknowledge how badly we need a savior.

For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— not by works, so that no one can boast. (Ephesians 2:8-9)

When we humbly come before God in need of a savior, He graciously covers us with His love and salvation through Jesus Christ.

Let’s dig further…

No One Is Good

Scripture tells us no one is good (Mark 10:18). In fact, this repeats throughout the Bible (Luke 18:19, Ecclesiastes 7:20, Psalm 14:3, Romans 3:23).

No one has ever walked this earth and lived an entirely sinless life. We all fall short of the glory of God.

That is, until our man Jesus enters the scene.

If anything proves that God is God, and a holy one at that, it is the life and time of Jesus. He is God incarnate.

Not once did Jesus exalt Himself over anyone, not even God.

Every time a Pharisee or follower or a curious onlooker showed Jesus any amount of attention or praise or worship, He pointed them straight to the Father in heaven, the One who sent Him!

Jesus makes it clear He does His Father’s will and not His own; He comes to serve, not to be served (Matthew 28:20).

I do as the Father has commanded me, so that the world may know that I love the Father. (John 14:31). 

Jesus lived sinlessly for 33 years on earth.

During that time, He faced seemingly impossible temptation, ruthless interrogation, and attacks at all angles.

Because of Jesus’ purity, His physical and spiritual state became no match for the world of darkness.

This is reassuring on many levels: Jesus not only saved us from the darkness, but experienced firsthand what it’s like to walk this earth. 

He experienced the bottom-most pits of human despair and anguish. 

So, Jesus knows how we feel navigating this fallen terrain.

And He feels for each of us, collectively and individually. 

Since the Beginning

Genesis 6:6 says God grieves over creating humans because of how detrimental we made the world become for ourselves. 

God never sleeps and has us in mind all the time. So much so that when the earth became spiritually polluted, He felt awful for what we now have to endure. 

God experienced in human form what it’s like to be used and mishandled by the very people who say they loved Him. And severely abused by those who hated Him.

Jesus was betrayed, mocked, violated, tortured, bruised, stabbed, scoffed, repeatedly downplayed, accused of being demonic, beaten, slandered, humiliated. And of course, publicly executed.

And yet, there’s insane beauty in this ugly act carried out by humankind: Jesus did it all for us.

He paid it all for us.

God sees how badly the earth is being destroyed by sin and darkness.

He sees the human race digging their own grave.

He sees our misery and sorrow and lowliness.

So He made a way. He became the way. 

I am the way and the truth and the life. No one comes to the father except through me. (John 14:6)

So, do those who think they’re a good person still need Jesus?

If you know you’re sick because of obvious symptoms, you go to the doctor.

But if you don’t know you’re sick because you can’t see the symptoms, are you going to go to the doctor?

There are so many out there who don’t realize how sick the human heart really is.

And many people do see it, but it’s usually someone else’s heart they recognize the sin of, not their own.

Which means some (or many) people don’t see the need for a savior. A savior who sprinted to the finish line of death and became sin (though He knew no sin) to atone for our filthy mess.

But the good news is, when we come to God knowing we need Him, He takes us in His arms and holds us real close.

Some may want to run on their own, but Jesus said we don’t have to labor hard.

Instead, we can walk on water with Him!

That, my friends, is true love.
