The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness. — Proverbs 15:2
Many years ago I was riding down the road in the ambulance with my partner. We were talking through life the way partners do on a long shift, the kind of conversation that fills the miles between calls. I was working through a decision I needed to make and thinking it out loud. And my partner offered some advice. It came quickly and confidently, the way advice often does when it hasn’t been thought through carefully.
I took the first step of that advice. And the moment I did, I knew it was a terrible idea. Not because my partner had bad intentions. The advice was given without the careful consideration the situation actually required. Words were poured out in the moment without being filtered through the wisdom the moment needed. And the result of following them was immediately and obviously wrong.
Solomon addresses this dynamic with striking precision. The tongue of the wise useth knowledge aright. There is restraint built into that phrase that is easy to read past. The wise person has something to say; they have knowledge, they have experience, they have a perspective that could be offered. But they use it aright. They choose carefully. They consider when to speak and when to hold back. They filter what they know through the question of whether saying it will actually help the person in front of them or simply relieve the pressure of having something to say.
The fool pours out foolishness. The image is unrestrained. An overflow. Whatever comes up comes out. Not always from a malicious place, often simply from an undisciplined one. The words leave the mouth before they have passed through any meaningful consideration of their weight or their impact or whether they are actually the right words for this particular moment.
The damage done by words released without wisdom is almost always greater than the person who spoke them intended.
Words are not neutral. They build, or they tear down. They bring clarity, or they create confusion. They heal wounds, or they open new ones. The advice that sent me in the wrong direction on that ambulance ride was not intended to harm, but its consequences were real regardless of the intent behind it. Words work that way. They land with the full weight of what they actually say, not just what was meant by them.
Jesus connected this directly to what is happening inside us. Out of the abundance of the heart, the mouth speaks. What we say under pressure reveals what is actually living in us. What we say when we think no one important is listening tells us something true about the current condition of our hearts. What we say about people who are not in the room shows us what we actually think rather than what we present.
The invitation of Proverbs 15 is not simply to talk less. It is to let wisdom govern what we say before we say it. To filter our words through the question of whether they reflect what God would have us speak into this moment. To use knowledge aright, which sometimes means offering what we know carefully and sometimes means recognizing that what we know is not what this moment needs.
Words, once released, cannot be taken back. They land somewhere, and they do something. Make sure what you are about to say is worth what it will cost when it arrives.
