Master Your Mouth, Master Your Life

“Anyone who is never at fault in what they say is perfect, able to keep their whole body in check.”

—James 3:2

Wow. According to James, if we can master our mouth, we can master our life.

I find that both inspiring and quite daunting. This summer I’ve been paying closer attention to my words—trying to master them rather than regretting them—and I’m seeing more clearly than ever why James connects something as ordinary as speech with something as profound as spiritual maturity.

Words do more than communicate. According to Scripture, they can actually change the atmosphere inside another human being.

Proverbs says, “Death and life are in the power of the tongue” (18:21). “The words of the reckless pierce like swords, but the tongue of the wise brings healing” (12:18). Gracious words are “sweet to the soul and healing to the bones” (16:24). The lips of the righteous “nourish many” (10:21). And in Job 4:4, Job was told, “Your words have supported those who stumbled; you have strengthened faltering knees.”

Whether we knew those specific Scripture passages or not, we all learned early on that words can damage or heal, build up or tear down. They can nourish or terrify, and even put strength back into someone who is losing theirs. According to the apostle Paul, words can go even further than that—they can “give grace to those who hear” (Ephesians 4:29, ESV).

Words can be carriers of God’s grace.

This shouldn’t surprise us. The Bible begins with God creating through words. And during Jesus’ ministry, His words continually created new realities inside people:

Your sins are forgiven.
Take courage.
Do not be afraid.
Peace be with you.
Your faith has healed you.

His words created new worlds inside His hearers.

Grace. Forgiveness. Courage. Peace. Healing.

What a beautiful possibility to carry into every conversation.

Which brings us back to James 3:2 and the question behind this essay: Why does the Bible connect our spiritual maturity with our speech, even describing the person who masters their words as perfect?

Here are two thoughts.

First, words are nuclear. They carry enormous power, and handling that power responsibly requires maturity. Responsibility always does.

Second, words reveal our inner state. For a person to be characterized by life-giving, God-honoring speech, they have to overcome a host of internal issues that can sabotage us and leak out through our words: anxiety, anger, jealousy, pride, foolishness, and more.

It isn’t that controlling our speech alone makes us perfect or spiritually mature. It is that tempered speech is the fruit of winning countless inner battles. To transform our speech, God must transform its source: us. And that is spiritual maturity.

So, let’s go to war.

Let’s deal with the issues that seep into other people through our words. Let’s learn to carry grace instead. And let’s become people whose words leave others stronger than we found them.
