When I was young, I was told talking to yourself was a bad thing—something only the old or senile did.
Yet the older I became, the more I developed the habit. Yikes! Does this mean there’s something wrong with me? Do I need to consult a psychiatrist or get into therapy?
Turns out the experts had it wrong.
The longer I live, the more the Bible shows itself to be true.
The Word of God tells us:
“Declare a thing, and it will be established for you, and light will shine on your ways.”
— Job 22:28
Romans 10:9 reminds us:
“If you declare with your mouth, ‘Jesus is Lord,’ and believe in your heart that God raised Him from the dead, you will be saved.”
Speaking God’s Word—the truth—out loud helps renew our minds in seasons of doubt.
Scientific Support
The brain has a remarkable capacity for recognizing and filtering familiar stimuli. This “neural sharpening” effect occurs because of a lifetime of exposure to our own voice, making it easier for the brain to process.
Did you catch that? Our brain responds best to our own voice.
“But you are a chosen people, a royal priesthood, a holy nation, God’s special possession, that you may declare the praises of Him who called you out of darkness into His wonderful light.”
— 1 Peter 2:9 (NIV)
A 2024 study in Brain Sciences found that hearing one’s own voice—especially during self-affirming internal talk—engages self-referential networks, linking self-processing with memory.
When we speak truth out loud, our brain helps us recall the faithfulness of God.
Our Personal History
I have come to know God in very intimate ways.
While trapped in the crush of a car wreck, He literally showed up and comforted me until I could be cut out of the wreckage.
He wrapped me in His presence as I lay beside my dad in his hospital bed before he passed into glory.
God strengthened me on the mission field as I extracted teeth, held dying babies, and recovered from Dengue Fever in Haiti.
I even found courage to sit on the floor of a psych hospital and hold my 28-year-old son’s head in my lap when he was not in his right mind.
Yes, I have an incredible personal history of walking with God during trying times.
So, when I come up against a trying circumstance, I run to Him—because we have history.
He knows my heart, and I trust His.
Spiraling Thoughts
Singing songs and engaging in spiritual practices can interrupt a negative mental spiral by altering brain chemistry and shifting focus away from catastrophic thinking. These activities promote calm and emotional balance.
Have you ever faced trials and heartaches that come like waves—one after another, without end?
It’s so easy to spiral down into a dark space.
That’s when it’s especially important to declare the Word of God out loud.
Once Again, Science Backs Up the Bible
Research shows that when a person is speaking, other areas of the brain quiet down.
If we find ourselves spiraling, we can silence that mental chaos by practicing Ephesians 5:19:
“Speak to yourselves with psalms, hymns, and spiritual songs, singing and making melody in your heart to the Lord.”
Another amazing fact: the brain can prioritize one familiar voice—like our own—amid background noise.
This is called the “cocktail party effect.”
So when you find yourself in a noisy or chaotic environment, it might be a perfect time to give yourself a godly pep talk.
“OK, girl, you got this—because the Lord is with you!”
Watch How You Talk to Yourself
Self-talk affects the brain by triggering the reward system and influencing neuroplasticity.
Positive self-talk boosts dopamine and strengthens resilience.
Negative self-talk activates stress responses and reinforces anxiety pathways.
So yes—the way you talk to yourself can change your brain.
David Knew This Life Hack
Psalm 42 is a beautiful example of how David “built himself up in the Lord.”
Most scholars believe he wrote it while in exile—far from Jerusalem and in deep struggle.
As you read this Psalm, you’ll see David recall God’s faithfulness, lament his distance, then declare his hope in the future.
“Why art thou downcast, O my soul? Why art thou disquieted within me? Hope thou in God, for I shall yet praise Him.”
— Psalm 42:5
Stop the Spiral
Jesus warned us that in this world we would have troubles—and we all know that’s true.
Let’s take our knowledge of how the brain works and combine it with the truth of God’s Word.
When you feel a spiral starting, the combination of praise and prayer can make all the difference.
Try this:
-
Keep a daily journal. Write your morning conversations with God using David’s blueprint: Remember, Lament, Declare.
-
Create a playlist of encouraging, scripture-based songs.
-
Breathe deeply — in for 4 seconds, hold for 4, exhale for 4, hold for 4.
-
Pause and ask the Holy Spirit: “Are these thoughts based on truth or assumption?” Replace lies with declarations of God’s Word.
-
Move your body — dance before the Lord, walk in nature, or listen to worship or a faith-filled podcast. Movement releases endorphins and shifts your focus from negative to positive.
“Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
Whatever you have learned or received or heard from me, or seen in me—put it into practice.
And the God of peace will be with you.”
— Philippians 4:8–9 (NIV)
Peace Instead of Spiraling?
I choose peace.


Positive self-talk makes such a difference!
I laughed because I have always talked to myself and processed out loud. Maybe because I live solo.
Thanks for showing how science integrates with scripture. Bless the Lord oh my soul!!
Satan will tell us that “you’re not good enough” and “God would never forgive THAT sin”. As you indicated, Diana, we have to speak Scripture or sing hymns to replace Satan’s negativity with God’s positivity and joy.
You pulled teeth?
Lots of great advice here! How interesting that our brain pays more attention to what is said in our own voice! Philippians 4:8-9 is such good advice.
