Are You Spiritually Mature or Just Spiritually Informed?

There is a danger that can exist in the church without looking like sin. You can know the Bible and not obey it. You can explain the gospel and fail to live by faith. You can listen to sermons every week, read Christian books, memorize Scripture, discuss theology, and accumulate years of Christian vocabulary and yet remain remarkably unchanged. It is possible to become spiritually informed without becoming spiritually mature. That is a sobering thought, and it is precisely the kind of danger Scripture warns us about.

Knowledge Is Necessary but Knowledge Is Not the Goal

Let's be clear from the beginning: Christianity is not anti-intellectual. Biblical Christianity cares deeply about truth. Paul prays that believers would be "filled with the knowledge of his will in all spiritual wisdom and understanding" (Colossians 1:9). He doesn't pray merely that they would feel closer to God. He prays that they would know God's will. But notice what comes next: "so as to walk in a manner worthy of the Lord, fully pleasing to him, bearing fruit in every good work and increasing in the knowledge of God" (Colossians 1:10). Biblical knowledge has a destination: a life that walks differently.

Paul wants the Colossians to know God's will so that they would walk worthy of Christ. Knowledge is not the finish line. It is meant to fuel faithful living. This is the biblical pattern: truth produces faith, faith produces obedience, obedience shapes character, and character increasingly reflects Christ. The problem isn't knowing too much. The problem is knowing without growing.

The Warning of Hebrews 5

The author of Hebrews confronts this problem directly. He has much to teach his readers about Christ, but he pauses because they have become "dull of hearing" (Hebrews 5:11). They have been Christians long enough that they should be teachers, yet they still need someone to teach them "the basic principles of the oracles of God" (5:12). Then comes the striking statement: "For everyone who lives on milk is unskilled in the word of righteousness, since he is a child" (Hebrews 5:13).

The issue isn't merely how much information they possess. The issue is that they haven't developed the spiritual capacity to live skillfully according to God's truth. Maturity is demonstrated in practice. Hebrews says that the mature are those "who have their powers of discernment trained by constant practice to distinguish good from evil" (5:14). Notice the language: trained by constant practice. Spiritual maturity doesn't come simply by sitting under more teaching. It comes as God's truth is received, believed, practiced, and worked into the fabric of our lives.

You can hear a thousand sermons and still need to learn how to forgive. You can memorize dozens of verses and still struggle to trust God when circumstances disappoint you. You can understand justification by faith and still live as though God's acceptance depends upon your performance. You can explain the sovereignty of God and still be controlled by anxiety. You can know that Christ commands humility and still insist on having your way. The question isn't simply, "What do you know?" It is also, "What is what you know doing to you?"

Informed or Transformed?

Paul describes the goal of Christian ministry in Ephesians 4. Christ gives pastors, teachers, evangelists, and other leaders to equip the saints for ministry and build up the body of Christ. And what is the intended result? "Until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood" (Ephesians 4:13). Notice that knowledge is absolutely part of maturity. Paul isn't minimizing it. But maturity doesn't stop at knowledge.

The result is that believers are no longer spiritual children, "tossed to and fro by the waves and carried about by every wind of doctrine" (4:14). Instead, they are to "grow up in every way into him who is the head, into Christ" (4:15). Into Christ. That is the goal. Christian maturity isn't becoming someone who can win every theological argument. It is becoming increasingly like Jesus.

As we grow in truth, we should become increasingly stable, humble, discerning, loving, holy, patient, courageous, forgiving, and faithful. Theology should have a trajectory. It should move from the head into the heart, from the heart into the hands, and from the hands into the ordinary patterns of our lives.

When Knowledge "Puffs Up"

First Corinthians 8 gives us another important warning. Paul writes about Christians who possessed correct theological knowledge regarding idols. They knew that an idol was nothing and that there was one God. Their theology wasn't necessarily wrong. But Paul says, "Knowledge puffs up, but love builds up" (1 Corinthians 8:1).

He isn't saying knowledge is bad. In fact, the chapter assumes that truth matters. His concern is knowledge without love. A person can know something true about God and become proud because of what they know. That's a frightening possibility for those of us who love theology.

We can know the right doctrines, use the right vocabulary, read the right authors, identify the right theological errors and still become impatient, arrogant, harsh, and uncharitable. Paul gives the corrective: "If anyone imagines that he knows something, he does not yet know as he ought to know" (1 Corinthians 8:2). Christian knowledge should produce humility because ultimately, the goal isn't merely knowing facts about God. It is being known by God and growing in love for God and others. If our increasing knowledge makes us increasingly proud, something has gone terribly wrong.

"Be Doers of the Word"

James makes the distinction even more plainly. "Be doers of the word, and not hearers only" (James 1:22). James describes someone who hears God's Word but doesn't obey it as a person who looks at his face in a mirror and immediately forgets what he looks like. The problem isn't the mirror. The problem is the response.

God's Word reveals us truthfully. It exposes our sin, corrects our thinking, confronts our excuses, and shows us what faithfulness looks like. But Scripture isn't given merely to inform us. It is given to transform us. The person who hears and acts is blessed in his doing (James 1:25).

So perhaps one of the most revealing questions we can ask after opening the Bible isn't, "What did I learn?" It is: "What am I going to do with what God just showed me?"

The Evidence of a Changed Life

Galatians 5 gives us one of the clearest descriptions of what spiritual transformation looks like. Paul describes "the fruit of the Spirit": love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

Notice that Paul calls this fruit. Fruit grows. It is the result of life. And it is specifically called the fruit of the Spirit. Christian maturity is not self-improvement powered by human determination. It is the Holy Spirit producing Christlike character in people who belong to Christ.

That means we should be careful about measuring maturity merely by visible religious activity. How much do I know? How many books have I read? How many sermons have I heard? How many Bible studies have I attended? How much theology can I explain? Those questions aren't meaningless. But Scripture presses us further. Am I becoming more loving? More patient? More self-controlled? More faithful? More humble? More willing to forgive? More courageous in obedience? More content in God's providence? More willing to serve when nobody notices? More repentant when confronted? More willing to submit my desires to the Word of God?

That is where maturity becomes visible.

From Consuming to Practicing

We live in an age of extraordinary Christian content. Sermons are available instantly. Books are abundant. Podcasts can accompany every commute. Bible studies are everywhere. Theological resources that previous generations could scarcely imagine are available at the touch of a screen. These are tremendous gifts.

But abundance creates a danger: we can consume discipleship without actually practicing discipleship. We can listen to a sermon about prayer without praying. We can read about evangelism without sharing Christ. We can study humility while defending ourselves at every opportunity. We can listen to teaching about marriage without loving our spouse sacrificially. We can learn about biblical community while remaining relationally disconnected. We can become experts at discussing spiritual formation while never actually submitting ourselves to the ordinary, sometimes uncomfortable work of being formed.

Christianity was never intended to be a spectator sport. Jesus didn't merely say, "Come listen to Me." He said, "Follow Me." Following requires movement. It requires trust. It requires obedience. It requires repentance. And sometimes it requires suffering.

The Ordinary Path to Maturity

How, then, does God mature His people? Not usually through spectacular experiences. He ordinarily uses ordinary means. He matures us through His Word, as Scripture renews our minds and exposes our hearts. He matures us through prayer, as dependence replaces self-sufficiency. He matures us through worship, as our hearts are continually redirected toward God's worth and glory. He matures us through the fellowship of the church, where other believers encourage, confront, forgive, teach, and sharpen us. He matures us through suffering, where truths we once affirmed intellectually become realities we must actually trust. And He matures us through obedience, as faith moves from confession into action.

None of this earns God's favor. We are not accepted by God because we have become sufficiently mature. We are accepted because of Christ. Our justification rests entirely upon the finished work of Jesus not our spiritual résumé. And precisely because we have been justified by grace, God continues His work of sanctification in us by grace.

The same Christ who saves us is the Christ who transforms us. The same Spirit who gives us new life is the Spirit who produces fruit. The same gospel that forgives our sin also teaches us to say no to ungodliness and to live self-controlled, upright, and godly lives (Titus 2:11–12). Grace doesn't leave us unchanged. Grace changes us.

A Spiritual Inventory

So, are you spiritually mature or merely spiritually informed? Don't answer too quickly. Take an honest look at your life. Am I becoming more like Christ, or simply becoming more knowledgeable about Christianity? Does Scripture regularly lead me to repentance and obedience? When God's Word confronts me, do I submit or explain it away? Is my theological knowledge producing humility or pride? Am I more patient and loving than I was five years ago? Do I forgive more readily? Am I increasingly faithful when obedience is costly?

Do I trust God's sovereignty when life doesn't go according to my plans? Am I known by other believers well enough for them to encourage and correct me? Is prayer becoming dependence rather than merely a religious duty? When I hear something challenging from Scripture, do I ask, "Who else needs to hear this?" or "Lord, what needs to change in me?" If someone examined the ordinary patterns of my life, would they see increasing evidence of Christ?

These questions aren't designed to make you despair. They are designed to help you look honestly at the evidence of God's grace. Because genuine faith bears fruit.

Don't Settle for Knowing About Jesus

The goal of Christianity isn't that you would someday become impressive at Christian trivia. It isn't that you would accumulate theological vocabulary. It isn't even that you would become the person everyone considers "the mature Christian." The goal is Christ.

Paul's great ambition was that believers would "walk in a manner worthy of the Lord" (Colossians 1:10). Peter calls us to "grow in the grace and knowledge of our Lord and Savior Jesus Christ" (2 Peter 3:18). And Paul tells us that God's ultimate purpose is that His people would be "conformed to the image of his Son" (Romans 8:29).

That's maturity. Knowing Christ. Trusting Christ. Following Christ. Obeying Christ. Becoming like Christ.

And we don't accomplish this by trying harder to manufacture a Christian life. We look to Christ. We abide in Christ. We depend upon His Spirit. We immerse ourselves in His Word. We gather with His people. We pray. We repent. We obey. We persevere. And through all of it, we trust the God who began His good work in us to carry it on to completion (Philippians 1:6).

So keep learning. Study deeply. Read good books. Know your Bible. Think carefully. Love sound doctrine. But don't stop there.

Let the truth you know become the truth you live. Let Scripture move from your Bible to your mind, from your mind to your heart, from your heart to your habits, and from your habits into the way you love God and love people.

Don't settle for being spiritually informed. By the grace of God, become increasingly spiritually transformed.

Because the mark of Christian maturity isn't simply that you know more about Christ. It is that, by His grace and through His Spirit, you are increasingly becoming like Christ.
