How to Grow Spiritually Mature in Christ

Spiritual maturity is not the same as longevity in a church. It is the unfolding of Christ’s life in us so that we stop living by fear and start living by the love and freedom Jesus provides. The real you is found in Christ. The journey from an old self to a new creation happens when your mind is renewed, your spirit is trained, and your heart learns to respond with love instead of fear.

The dream that drives spiritual growth

Many churches focus on getting people to make a right profession of faith. That is important, but if the goal stops at afterlife assurance, the church misses something gigantic. The Apostle Paul imagined a church of mature believers who reflect Christ and change the world with grace, healing, and life. That kind of maturity produces leaders, creativity, and flourishing for communities. It is not about time served. It is about transformation.

From the old self to the new self

Colossians gives the core image: we have “put off the old man” and “put on the new man who is renewed in knowledge according to the image of him who created him.” This is not merely an identity label. It is an ongoing reality to be reproduced in daily life. The new self grows as our knowledge of Christ increases and our mind is reshaped to think like him.

Expectation shapes growth

How we speak to one another matters. People rise to expectation. Paul writes as if maturity is the assumption, not the exception. When leaders treat people as capable of reflecting Christ, those people often respond and grow into that expectation. Low expectations tend to reproduce low outcomes. High expectations can produce transformation.

How growth actually happens

Growth is practical. It is not abstract or merely emotional. Three realities drive spiritual maturity:

• Renewing the mind — The command to be transformed by the renewing of your mind is central. Renewed knowledge of Christ changes how you see yourself and your circumstances.
• Walking in the Spirit — Obeying the Spirit trains you to respond in love rather than react in fear or anger. This training is repeated and practical.
• Discernment — Learning to tell what is alive and what is dead, what brings life and what steals it, is essential to communal maturity.

Practical training: when your buttons get pushed

Emotional triggers reveal exactly where growth is needed. Avoiding the people who push your buttons robs you of becoming more like Christ. Engaging with them, asking God for grace, and practicing love in the moment are the gym of spiritual maturity.

Sometimes the honest prayer is, “God, I do not have this in me. Fill me.” That humility opens the door for real change. When the knowledge that God loves the other person hits your mind, it can spark a willingness to seek grace and receive transformation.

Trials are not meaningless

Trials train the inward man. Paul says our outward affliction is temporary while the inward man is renewed day by day. How you interpret suffering determines whether it destroys you or helps you grow. Fixing your eyes on the unseen realities of God gives trials a purpose and a horizon of hope.

Stories that teach perspective

Sue Burns suffered severe osteoporosis to the point she could not leave her bed. Rather than sink into despair she chose an outward focus. From her bedside she called others who were suffering, encouraged them, prayed for them, and found purpose inside pain. Her life became a ministry because she asked, “What might God do through me in this condition?”

Isaac Pearlman, a violinist who lived with paralysis, once lost a string just as a concerto began. He did not stop. He signaled the conductor and played the whole piece on three strings. Afterward he said, “Our task is to make music with what remains.” That perspective transforms limitations into ministry.

“Our task is to make music with what remains.”

Grace, prayer, and the throne of mercy

Maturity is not moralism. It is not more rule keeping. It is life born of grace. When failure happens, there is an advocate at the Father who offers mercy. That truth removes the shame that cripples growth and invites humble, persistent prayer. Often the most honest prayers come from desperation and lead to the deepest encounters with God.

The real you is Christ in you

“I have been crucified with Christ. It is no longer I who live, but Christ lives in me.” Galatians 2:20

This is the foundation of spiritual maturity. The life we now live is Jesus living through us by faith. The goal of growth is not to earn acceptance but to manifest the life already given. That life learns to see the unseen, to value people, and to embody love in practical ways.

The inward man and Paul’s prayer for fullness

Paul prayed that believers would be strengthened in the inner man by the Spirit so that Christ might dwell in their hearts through faith. He prayed that we would grasp the width, length, depth, and height of Christ’s love so fully that we would be filled with all the fullness of God. This is not fanciful language. It is a prayer for whole life transformation that results in a church able to shine in dark places.

“That you being rooted and grounded in love may be able to comprehend with all the saints what is the width and length and depth and height to know the love of Christ which passes knowledge that you may be filled with all the fullness of God.”

Practical next steps

1. Read Scripture with renewed intention — Ask how a verse reshapes your thinking about yourself and others.
2. Practice one Spirit led response — When your button is pushed, pause, pray, and choose love.
3. Use trials as training — Ask, What might God be doing in this? Seek purpose inside pain.
4. Engage community — Receive gifts from people who are hard to love; humility accelerates growth.
5. Go to the throne of grace — When you fail, bring honest dependence and receive mercy to try again.
6. Expect maturity — Speak hope into the church. Believe people can be more like Jesus.

Final encouragement

Be convinced that growth is possible because Christ is working in you. The work is his not yours. You are invited to cooperate with him, to let your mind be renewed, to walk by the Spirit, and to let Christ’s life in you become the hope of glory for those around you. This path is the most exciting purpose any life can have.
