Your Speech Is Saying More Than You Think (Proverbs 18:4)
Listen Here:
Proverbs 18:4
The words of a man's mouth are deep waters;
the fountain of wisdom is a bubbling brook.
Last week, we reflected on friendships — how they shape us, sharpen us, or sometimes, sadly, wound us. And that naturally leads to another powerful form of influence: our words.
If you’ve been with us this year, you’ve noticed how often Proverbs returns to the theme of speech. It's not a footnote. It's central. Solomon circles it like a hawk, again and again. Which tells us something: our words are not peripheral to wisdom — they’re diagnostic of it.
So here we are again, drawing from the well of Proverbs, and this time, we’re invited to consider not just what we say — but what our speech reveals about us.
“The words of a man's mouth are deep waters…”
This line can be read in more than one way. On one hand, it could describe the complexity — even the murkiness — of human speech. Sometimes what we say is confusing or difficult to interpret. But I think the deeper meaning is this: our words are windows into our souls. Or to borrow from pastor David Guzik:
“The idea is not that everyone’s speech is deep and meaningful. The idea is that we reveal the depths of our heart by the words of our mouth.”
In other words, our speech is not just communication. It’s revelation.
Your words — casual, cutting, or careful — aren’t random. They’re pulling from a deeper place. They’re like a ladle dipped into your inner reservoir. And what comes out tells you something about what’s within. That water might be clear and nourishing — or cloudy and toxic. But either way, it's not superficial.
Now maybe that feels overstated. You might think, “Isn’t that a bit much? I say a lot of dumb things, but that doesn’t mean I’m a bad person.” But Jesus said something startlingly similar in Luke 6: “Out of the abundance of the heart, the mouth speaks.”
So what you say in passing, in traffic, in texts, in conflict — it’s all disclosing something. Not just your thoughts. Your loves. What you fear, what you crave, what you’re trying to prove or protect.
“…but the fountain of wisdom is a bubbling brook.”
Now this is the contrast. If the first image is of deep, hidden water, this is fresh, flowing water. Public, not private. Life-giving, not self-revealing. In other words, this is what speech becomes when the heart is wise. When the soul is soaked in God’s Word and the Spirit’s presence.
You know people like this. Their words don’t dominate the room, but they nourish it. They don’t perform or pontificate — they refresh. You leave conversations with them feeling steadier, seen, maybe even sanctified. Their presence isn’t just pleasant. It’s like a bubbling brook.
That’s what the Spirit wants to form in you and me — not just a polished tongue, but a wise heart that overflows with grace.
And here’s the hope: this transformation isn’t achieved by willpower alone. You don’t become a bubbling brook by building a blockade for bad words. You become it by being filled. By abiding in the Word made flesh — Jesus — who not only spoke life but is the Living Water.
When Christ dwells richly in us, as Paul says in Colossians 3, our speech becomes shaped by Him. Gentle. Bold. Joyfully true. Not because we’ve learned a new vocabulary — but because we’ve received a new heart.
So maybe today’s question is simple, but revealing:
What’s flowing from your mouth lately?
What does it say about what’s happening in your heart?
Let’s pray this morning that our mouths would be bubbling brooks and fountains of life, pointing to and glorifying Christ.
