The Tongue Test: A Measure of Christian Maturity (A Faith that Works)

One of the things Scripture addresses most often is one of the things that many of us tend to

ignore: the spiritual importance of how we use our words to build up or tear down. The human tongue may weigh only a few ounces, but it holds the power to heal or destroy, build up or tear down, bless or curse. 

James 3 offers one of the most sobering pictures in all of Scripture about the power of our words. In this chapter, James compares the tongue to a bit in a horse’s mouth, a rudder on a ship, and a spark that can set a forest ablaze. Those are some pretty big metaphors, and his point is this: small things can have big consequences. 

What was true in James’ day is even more true in ours. In an age of social media rants, political tribalism, and relational division, James’s words are amplified. Our words reveal the condition of our hearts, and they have the power to shape the world around us. 

A Small Spark, a Great Fire 

James doesn’t mince words on this topic. He writes, “The tongue is a fire, a world of unrighteousness... setting on fire the entire course of life” (Jas. 3:6). Indeed, what makes the tongue so dangerous is that it can cause great damage with little effort. A harsh comment. A sarcastic remark. A whispered bit of gossip. These can ripple through relationships, communities, and even generations. 

James’s imagery is vivid because the danger is real. Just like a single match can burn down a forest, a single comment can ruin a reputation, fracture a friendship, or wound a child’s spirit. 

But the flip side is also true: Just as the tongue can destroy, it can also give life. Proverbs reminds us, “Death and life are in the power of the tongue” (Prov. 18:21). 

Why Words Matter 

Why do words matter? To understand that, we are wise to go back to the beginning, where we find speech woven into the grain of the universe. The Bible tells us that God created the universe through His Word (Gen. 1). It also refers to Jesus as “the Word made flesh” (John 1:14). And it refers to Scripture itself as the Word of God, given to shape us into the image of Christ. 

In that light, it’s no wonder our words carry such weight. As image-bearers of God, we’ve been entrusted with the power of speech. And what we say reveals what’s going on in our souls. 

Jesus said, “Out of the abundance of the heart the mouth speaks” (Matt. 12:34). If bitterness, pride, or anger take root in our hearts, it won’t be long before they show up in our speech. 

A Litmus Test for Spiritual Fitness 

One of the best indicators of spiritual maturity is not how many Bible verses we can quote. It’s how we talk to the people around us. 

Here’s how James puts it: he says that anyone who can tame the tongue is “a perfect man, able also to bridle his whole body” (Jas. 3:2). That’s a pretty high bar. And it reveals just how difficult it is to bring our speech under the lordship of Christ. 

But here’s the hopeful news: our tongues don’t have to stay out of control. As our hearts are shaped by Scripture absorption and spiritual fitness, our speech begins to reflect that transformation. 

It won’t happen overnight. But it will happen over time—as we confess, repent, and invite the Holy Spirit to train our mouths the way He trains our hearts. 

Practical Ways to Tame the Tongue 

If James’s words feel convicting, you’re not alone. All of us stumble in what we say (Jas. 3:2). But here are three practical ways to pursue growth in this area: 

1. Slow Down Before You Speak 

James offers this simple but profound counsel: “Let every person be quick to hear, slow to speak, slow to anger” (Jas. 1:19). Don’t rush to fill silence. Don’t speak when emotions are high. Give your mouth a moment to catch up to your heart. 

2. Ask Before You Post 

In today’s digital world, words don’t disappear—they echo. Before you post that comment or share that article, ask: Does this reflect the character of Christ? Will this build up or tear down? 

Even when you’re “right,” tone and timing matter. 

3. Replace Criticism with Encouragement 

It’s easy to tear down. It takes intentionality to build up. Look for opportunities to bless others with your words—a text of encouragement, a word of thanks, or a sincere compliment. 

As Paul wrote, “Let your speech always be gracious, seasoned with salt” (Col. 4:6). 

Let Scripture Shape Your Speech 

Ultimately, the only way to tame the tongue is to saturate our hearts with the truth of God’s Word. The more time we spend in Scripture—listening, meditating, absorbing—the more our speech begins to align with the heart of Christ. 

It’s not just about controlling what we say. It’s about allowing God to so transform us on the inside that what comes out of our mouths is life-giving, grace-filled, and truth-anchored. 

Because in the end, your words matter. They’re not just sound waves. They’re spiritual seeds—planting peace or division, hope or harm, healing or destruction. Sticks and stones can break our bones, and words can definitely hurt us. 

So guard your tongue. Train your heart. And allow God to guide your tongue so that you speak as someone who is filled with the grace of God.
