When a person comes to Christ, they are saved, but they are not instantly mature. A new believer has much to learn. Old habits may still be there, and old ways of thinking need to change. There will be temptations, failures, questions, and times when growth seems slow. That does not mean something is wrong. Spiritual growth takes time.
Peter compared new believers to newborn babies when he wrote, “like newborn babies, long for the pure milk of the word, so that by it you may grow in respect to salvation” (1 Peter 2:2). A baby is alive, but a baby must grow. The same is true spiritually. A believer has received new life in Christ, but now that life must grow and mature.
Spiritual growth does not make us more saved. We are saved by the grace of God through faith in Jesus Christ. “For by grace you have been saved through faith; and that not of yourselves, it is the gift of God” (Ephesians 2:8). We do not read the Bible, pray, obey God, or attend church in order to earn salvation. We do those things because we belong to Christ and want to grow in Him.
One of the most important parts of spiritual growth is God’s Word. Jesus said, “Man shall not live on bread alone, but on every word that proceeds out of the mouth of God” (Matthew 4:4). Your body needs food, and your spiritual life needs God’s Word. You will not grow very much if the only Scripture you hear is during a sermon once a week. Read the Bible for yourself. Think about what you read. Ask what the passage says, what it means, and what God wants you to learn from it.
Paul wrote, “All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness” (2 Timothy 3:16). Sometimes Scripture teaches us something we did not know. Sometimes it corrects something we believed that was wrong. Sometimes it exposes sin in our lives, and sometimes it gives encouragement when we need it. God uses His Word to change the way we think and live.
Simply reading the Bible, however, is not enough. James wrote, “But prove yourselves doers of the word, and not merely hearers who delude themselves” (James 1:22). Spiritual growth requires obedience. You may read a passage about forgiveness and realize there is someone you refuse to forgive. You may read about honesty and realize you have been dishonest. You may read about controlling your tongue, sexual purity, loving others, or helping someone in need. At that point, growth means doing what God has said. Jesus said, “If you love Me, you will keep My commandments” (John 14:15). Obedience does not save us, but obedience is part of following Christ.
Prayer is also necessary for spiritual growth. Prayer does not have to be complicated. Talk to God honestly. Thank Him for what He has done. Confess your sins. Ask for wisdom. Pray for other people. Bring your fears, needs, and struggles to Him. Paul wrote, “Devote yourselves to prayer, keeping alert in it with an attitude of thanksgiving” (Colossians 4:2). You do not need special religious words. God already knows what is in your heart.
As you grow, you will also learn how much you need the Holy Spirit. The Christian life cannot be lived successfully by human strength alone. Paul wrote, “But I say, walk by the Spirit, and you will not carry out the desire of the flesh” (Galatians 5:16). The flesh pulls us toward sin, while the Holy Spirit leads us toward obedience to God.
As the Holy Spirit works in a believer’s life, His fruit begins to appear. Paul described “the fruit of the Spirit” as “love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control” (Galatians 5:22–23). Notice that these are changes in character. Spiritual maturity is not measured by how many Bible facts you know, how long you have attended church, how loudly you worship, or how religious you appear. A person may know a great deal about the Bible and still be proud, angry, dishonest, unforgiving, or selfish.
Real spiritual growth changes the person. You begin to love what God loves and hate what God hates. You become more aware of sin in your own life and quicker to repent when you recognize it. You begin to become more patient with others, more willing to forgive, and more concerned about pleasing God than pleasing yourself. Those changes will not happen overnight, but over time there should be evidence that Christ is changing you.
There will still be failures. John wrote to believers, “If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1:9). When you sin, do not hide from God or pretend it did not happen. Confess it, turn from it, learn from it, and continue following Christ. A growing believer does not become sinless, but a growing believer becomes increasingly unwilling to make peace with sin.
Fellowship with other believers also matters. Hebrews tells us to “consider how to stimulate one another to love and good deeds, not forsaking our own assembling together” (Hebrews 10:24–25). Christians need other Christians. You need encouragement, teaching, prayer, and fellowship. Sometimes you also need another believer who cares enough about you to tell you when you are wrong.
At the same time, be careful who teaches you. Do not assume that every preacher, teacher, church, video, or Christian book is correct simply because it uses the name of Jesus. The believers in Berea listened to Paul, but they still checked what he taught against Scripture. Acts 17:11 says they were “examining the Scriptures daily to see whether these things were so.” That is part of growing spiritually. Learn to compare everything you hear with the Word of God.
Trials will also cause you to grow. Nobody enjoys difficult times, but God can use them to strengthen your faith. James wrote, “Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance” (James 1:2–3). You may learn more about trusting God during a hard season than during months when everything is going well. Trials show us what we really believe. They can teach patience, expose weaknesses, drive us to prayer, and remind us how much we need God.
Spiritual growth also involves serving others. Christianity is not only about what we receive. Peter wrote, “As each one has received a special gift, employ it in serving one another as good stewards of the manifold grace of God” (1 Peter 4:10). Look for ways to help people. Encourage someone. Pray with someone. Give when there is a need. Share what God has taught you. Point someone to Christ. You do not need a title or position in a church to serve God.
One of the dangers in the Christian life is becoming satisfied with where we are. A person may have been a Christian for twenty years and begin to think there is little left to learn. Peter wrote, “but grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18). That instruction was written to believers. As long as we live, there is room to grow.
Do not compare your spiritual growth with someone else. Some people have followed Christ for many years, while others have only recently believed. Instead, look honestly at your own life. Are you understanding Scripture better than you once did? Are you becoming more obedient? Are you quicker to recognize and confess sin? Are you learning to trust God during difficult times? Are love, patience, kindness, faithfulness, and self-control becoming more visible in your life? Those are signs of spiritual growth.
Jesus gave us the heart of spiritual growth when He said, “Abide in Me, and I in you. As the branch cannot bear fruit of itself unless it abides in the vine, so neither can you unless you abide in Me” (John 15:4). He continued, “I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit” (John 15:5).
A branch produces fruit because it remains connected to the vine. In the same way, spiritual growth comes from remaining close to Christ. Read His Word, pray, obey what you understand, confess sin when you fail, spend time with faithful believers, learn through trials, and serve others.
You will never reach a point in this life where you have finished growing. The goal is not simply to know more about Christianity. The goal is to become more like Christ.
