Changed Part 5: Changing My Mouth
The Power of Words: How Taming the Tongue Changes Everything
The power of words is not hypothetical. Every conversation you have today is either building something or breaking something, and most of us have never stopped long enough to reckon with which one it is. Taming the tongue is not about policing vocabulary; it is about understanding that your words carry the weight of life and death. A changed life produces a changed mouth, and that change starts by being honest about the damage an unguarded one can do.
Are You Speaking Life or Death? What the Power of Words Really Means
Proverbs 18:21 stops most readers cold the first time they sit with it: "The tongue has the power of life and death, and those who love it will eat its fruit." King Solomon was not speaking in metaphors. The power of words is the reason you can still remember, decades later, exactly what someone said to you as a child that made you feel worthless. Words do not expire.
Pastor Travis Hearn, Senior Pastor of Impact Church in Scottsdale, Arizona, opened this message by asking the congregation to imagine two identical bottles of water. One is filled with clean drinking water. The other is filled with poison. From across the room, you cannot tell the difference. That is what our words are every single day: a choice between what gives life and what takes it. Speaking life is not just a spiritual idea; it is a decision made in the kitchen before coffee, in the car during traffic, in the text message sent without thinking.
Solomon adds in Proverbs 18:21 that those who love their words will eat the fruit of them. Your words are seeds, and eventually you will live in the world those seeds have created.
One honest step to take today: before your next difficult conversation, pause and ask four questions. Is what I am about to say true? Is it necessary? Is it helpful? Is it loving? If any answer is no, do not say it.
What Your Words Reveal About What Is Really in Your Heart
In Luke 6:45, Jesus said something that should make every one of us uncomfortable: "For the mouth speaks what the heart is full of." He did not say the mouth creates the heart. He said the mouth reveals it. Our words are not the problem; they are the symptom. They are an X-ray of whatever is actually stored inside us, and the results are on display in every conversation we have.
Pastor Travis used a simple illustration to drive this home. If you are carrying a cup of coffee and someone bumps into you, what spills out? Coffee. Only what was already inside. Life bumps all of us: a hard marriage conversation, a traffic jam, a child who will not listen. When life bumps you, whatever comes out is not caused by the bump. The bump only reveals what was already there. Words reveal your heart; they do not manufacture it.
This is why behavior modification never works long-term. Jesus is not interested in helping you carry your cup more carefully. He wants to change what is inside it, so that when life bumps you, something different comes out.
Guarding your mouth, then, starts with a harder question than what you said. It starts with asking why it was in you to begin with, and bringing that honestly to God.
One honest step to take today: the next time you say something you regret, resist the urge to apologize and move on. Ask yourself what was already in you that came out, and bring that to God.
Some Words Have No Place in a Changed Life: Stopping Gossip, Slander, and Lying
James, the half-brother of Jesus and a pastor in Jerusalem, wrote an entire chapter about the tongue. In James 3, he compares it to fire: a good servant, but a terrible master. One tiny spark can take down an entire forest. One rumor can take down a marriage. One lie can burn a reputation to the ground that took decades to build.
Stopping gossip is not simply a matter of good manners. Gossip disguises itself in religious settings as concern: "I just thought you should know," or "I'm only telling you because I'm worried about them." But information shared about someone without their knowledge, even true information, is gossip if it does not help them. Most gossip, Pastor Travis pointed out, is born from insecurity. When something is broken in us, we create a false sense of security by tearing someone else down. Stopping gossip requires confronting what is broken inside, not just zipping the lips.
Slander and lying fall in the same category. A half-truth is a whole lie. The Apostle Paul in Ephesians 4:29 did not say reduce the unwholesome talk; he said do not let it come out of your mouth at all. The standard is not improvement; it is transformation.
One honest step to take today: for the next 30 days, commit to not repeating something you heard about someone else unless you would say it directly to their face.
What Does Proverbs 18 Say About the Tongue and the Fruit of Your Words?
Proverbs 18:21 draws a straight line between what you say and what you eventually live in. Here are four anchors from this sermon:
1. Guard Your Mouth
The Command: Proverbs 21:23 says those who guard their mouths and their tongues keep themselves from calamity.
The Application: In Solomon's day, guarding your mouth meant what you said out loud. In ours, it means every text, every post, every comment, every direct message. The platform does not change the standard.
2. Let Your Mouth Reveal a Changed Heart
The Root: Jesus in Luke 6:45 said the mouth speaks what the heart is full of. Words reveal your heart, which means the place to start is not the lips; it is what God is doing on the inside.
The Application: Stop apologizing for what spills out and start asking God to change what is in the cup.
3. Remove What Does Not Belong
The Standard: Paul writes in Ephesians 4:29 that only what builds others up according to their needs should come out of your mouth. Gossip, slander, lying, and profanity have no place in a life being transformed from the inside out.
The Application: The question is not "is it true?" It is "is it helpful, is it loving, and does it build up the person who hears it?"
4. Consecrate Your Mouth to God
The Meaning: To consecrate means to set apart as holy for God's exclusive use. In the Old Testament, the priests, the temple, and the altar were all consecrated. They were no longer common; they were set apart entirely for God.
The Application: A consecrated mouth does not just avoid bad words. It actively speaks life, healing, faith, and encouragement as an act of worship in every conversation.
When Words Feel Like Wounds: Finding Your Footing in the Phoenix Valley
There are people across the Phoenix Valley right now carrying wounds that were not left by fists. They were left by words. Whether you are in North Scottsdale or South Scottsdale, in Tempe or Gilbert, in Chandler or Paradise Valley, or anywhere across Maricopa County, the ache of something hurtful said by someone who was supposed to love you does not care what zip code you live in. If you are starting to realize you may also be the one doing the damage, Impact Church in Scottsdale is a place where people can get honest about both sides of that without shame, and start experiencing real transformation from the inside out.
A Changed Life Produces a Changed Mouth
A changed heart produces changed words, and changed words have the power to change the world around you. You do not have to keep living in the wreckage of an unguarded mouth. The path forward is not more willpower; it is a heart that has been genuinely transformed by God, which eventually changes everything that comes out of it.
If you are carrying something you have never said out loud, or something that was said to you that you have never let go of, you are welcome to bring it to God right now. Submit a prayer request here, and someone at Impact Church will be praying with you.

Frequently Asked Questions
-
The Bible is direct about this: Proverbs 18:21 says the tongue holds the power of life and death, and those who love their words will eat the fruit of them. Jesus adds in Luke 6:45 that the mouth speaks whatever the heart is full of. Scripture treats the words we speak as seeds that eventually grow into the world we live in, for better or worse.
-
Start by recognizing that most gossip is driven by insecurity, not concern. The book of James does not just say to avoid repeating gossip; it says not to even listen to it. Run every piece of information through a filter: is it true, is it necessary, is it helpful, and is it loving? A half-truth, according to the Bible, is still a whole lie. Real change in this area starts with the heart, not just better habits.
-
The answer Jesus gives is not behavior management; it is heart transformation. In Luke 6:45, he says the mouth reveals what is already stored in the heart. So the first step is not "try harder not to say it" but "ask God to change what is in me." Practical accountability helps too: find someone who will check you when you slip, and commit to a defined window, like 30 days, of intentional change. Sustained transformation starts on the inside and works its way out.
-
To consecrate something means to set it apart as holy for God's exclusive use. In the Old Testament, the priests, the temple, and the altar were all consecrated: no longer common objects used for anything. Applying that to your mouth means your words are no longer yours to use however you feel. They belong to God, which changes how you speak to your spouse, your kids, your coworkers, and yourself. A consecrated mouth does not just stop saying bad things; it actively looks for ways to speak life, healing, and encouragement.
-
According to Proverbs 18:21, yes. King Solomon says your words are seeds and you will eventually live in the world those seeds have created. If fear is all you speak, you will live afraid. If criticism is all you produce, cynicism becomes your home. But consistently speaking faith, hope, gratitude, and the promises of God over your life plants a different kind of harvest. Your words do not just reflect your reality; over time, they help to shape it.
