What the Bible Says About Spiritual Growth and How to Grow Closer to God

There was a time in my life when I thought spiritual growth meant being perfect—never doubting, never failing, and always doing everything right. But over the years, I’ve realized that spiritual growth is not about perfection. It’s about progress. It’s about walking closer with God every single day, even when the path feels slow or unclear.

The Bible has so much to say about how we can grow spiritually. It teaches that spiritual growth is a journey that begins when we accept Jesus Christ and continues as we live in obedience to His Word and depend on His Spirit.

Let’s take a heartfelt look at what Scripture says about growing in our faith.

1. Spiritual Growth Begins with a Relationship with Jesus

The Bible tells us that spiritual growth starts when we give our hearts to Christ. In 2 Peter 3:18, it says, “But grow in the grace and knowledge of our Lord and Savior Jesus Christ.”

That means growth isn’t about religious rules but about knowing Jesus personally. It’s about learning to trust Him, lean on Him, and let His Word transform our hearts.

When I began reading the Bible daily, even if it was just one verse, I noticed how my heart slowly began to change. That’s what growth looks like—it’s quiet, steady, and real.

2. The Word of God Nourishes Our Spiritual Life

In 1 Peter 2:2, Scripture says, “Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation.”

Just as our bodies need food to survive, our souls need the Word of God to grow. Reading the Bible daily helps us understand God’s character, His promises, and His love for us.

Even when we don’t fully understand everything, the Word strengthens our faith and keeps us rooted in truth.

3. Prayer Is the Key to Spiritual Maturity

One of the most beautiful ways to grow spiritually is through prayer. Prayer connects us directly with God. In Philippians 4:6-7, the Bible says, “Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.”

Prayer isn’t just asking for things—it’s talking to your Heavenly Father. It’s sharing your heart, listening for His voice, and finding peace in His presence.

When I started being honest in my prayers—telling God about my fears and failures—my relationship with Him became more real than ever.

4. Growth Happens When We Allow God to Transform Our Minds

The Bible teaches that true change begins within. Romans 12:2 reminds us, “Do not be conformed to this world, but be transformed by the renewing of your mind.”

Spiritual growth means letting God reshape our thoughts and desires. The more time we spend in His Word, the more our hearts align with His will.

It’s not about trying harder—it’s about surrendering more.

5. The Fruit of the Spirit Is Evidence of Growth

As we walk with God, the Holy Spirit begins to shape our character. Galatians 5:22-23 lists the fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

These are not just words—they are qualities that begin to show up in our daily lives when we let God lead us. I’ve found that even small moments of patience or kindness are signs that God is working in me, helping me grow in ways I couldn’t on my own.

6. Trials Strengthen Our Faith and Character

Sometimes, spiritual growth happens through pain. The Bible says in James 1:2-4, “Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance.”

It’s not easy to rejoice in hardship, but every challenge becomes a chance to grow stronger in faith. God uses difficulties to deepen our trust in Him and refine our hearts.

7. Spiritual Growth Is a Lifelong Journey

Growth doesn’t happen overnight. It’s a process that continues until we meet Christ face to face. Philippians 1:6 says, “He who began a good work in you will carry it on to completion until the day of Christ Jesus.”

That means God is not finished with you yet. Every day, He’s shaping you, teaching you, and preparing you for something greater.

Final Thoughts

So, what does the Bible say about spiritual growth?
It says that growth is a relationship, not a race. It’s about walking closely with Jesus, letting His Word guide you, and allowing His Spirit to change you from within.

You don’t need to have it all together to grow. You just need to keep showing up—keep reading, keep praying, and keep trusting.

Because the more time you spend with God, the more you’ll notice His peace filling your heart, His wisdom guiding your choices, and His love shaping your life.

Spiritual growth is not about how fast you move—it’s about how deeply you root yourself in Christ.
