Jesus said something both simple and searching:
“For whatever is in your heart determines what you say. A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart.” (Luke 6:45)
These words remind us that our speech is not random. It is a reflection. What comes out of our mouths reveals what is stored in our hearts.
Words Are Windows to the Heart
We often excuse our words by saying, “I didn’t mean that,” or “It just slipped out.” But Jesus says our words don’t slip out — they flow out. They reveal what’s been living inside us.
If our speech is consistently critical, bitter, sarcastic, or negative, it’s not just a communication problem. It’s a heart issue. And if our words are consistently encouraging, gracious, truthful, and life-giving, that also reveals something beautiful about what God is doing within us.
Two Treasuries, Two Outcomes
Jesus uses the word treasury — a storehouse, a vault, a place where things are kept and accumulated over time.
- A good heart stores truth, grace, gratitude, forgiveness, and faith — and produces words that build others up.
- A corrupted heart stores resentment, pride, fear, envy, and bitterness — and produces words that tear down.
In other words, our daily input determines our daily output.
This Is Not About Perfection — It’s About Direction
None of us speak perfectly. We all stumble with our words (James 3:2). But Jesus is not calling us to flawless speech — He is calling us to heart transformation.
The goal isn’t to manage our mouths better.
The goal is to let God shape our hearts deeper.
When the heart changes, the speech follows.
How Do We Build a Good Treasury in the Heart?
Here are some practical ways to cultivate a heart that produces life-giving words:
- Fill your heart with God’s Word.
What you meditate on will eventually come out of your mouth. Regular Scripture intake reshapes your thinking and your speech. - Practice gratitude daily.
A thankful heart produces thankful words. Try naming three things each day that you’re grateful for — out loud. - Guard what you consume.
What you watch, listen to, and dwell on feeds your heart. Choose content that strengthens your spirit, not weakens it. - Ask God to search your heart.
Psalm 139:23–24 invites us to say, “Search me, O God, and know my heart…” Invite the Holy Spirit to reveal and heal what’s unhealthy inside. - Choose blessing over venting.
There’s a time to process honestly, but make it your habit to speak words that bless rather than words that poison.
Final Thought
Jesus is not just teaching about speech — He’s inviting us into heart renewal. He wants our lives, relationships, families, churches, and ministries to be shaped by words that heal, strengthen, and point people toward God.
So here’s the takeaway:
If you want to change your words, focus on your heart.
