True spiritual growth, in a Christian’s life, looks like real change over time, change in what I love, what I pursue, how I think, how I respond, and what I value. Scripture tells me to “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Pet 3:18), and that growth is not just information; it is transformation. It is what happens when I keep receiving Christ and then actually walk in Him, “rooted and built up in Him and established in the faith” (Col 2:6–7). In simple terms, spiritual growth looks like someone who no longer acts or behaves as they once did, because Christ is shaping them from the inside out (2 Cor 3:18).
One of the clearest pictures of that growth is maturity. Paul explains it plainly: “When I was a child, I spoke as a child… but when I became a man, I put away childish things” (1 Cor 13:11). Hebrews expands that same idea and shows me what immaturity looks like: being stuck at the basics, needing “milk and not solid food,” staying “unskilled in the word of righteousness,” and never developing discernment (Heb 5:12–14). But maturity looks different: “solid food belongs to those who are of full age… who by reason of use have their senses exercised to discern both good and evil” (Heb 5:14). So true growth is not me staying the same while claiming faith, it is me learning the Word, using it, and becoming more discerning and steady over time (1 Pet 2:2–3; 1 Tim 4:15).
For me, the evidence of growth is that I can look back and honestly say I am not the same man I used to be. I used to pursue what the world offers as if it could satisfy my soul, what Scripture calls “the lust of the flesh, the lust of the eyes, and the pride of life” (1 John 2:15–17). I chased the “works of the flesh,” thinking they would fill the empty places in me, but I learned the hard way that the flesh never truly satisfies; it only keeps demanding more. Coming to faith in Christ opened my eyes to how temporary those pursuits are, and how they can quietly dominate us. That is part of what Scripture means when it says not to be “conformed to this world, but… transformed by the renewing of your mind” (Rom 12:2). My mind started changing, and over time, my appetites started changing too.
Today, I sit here writing this response not because I have to, as if it were some cold obligation, but because I want to live a life that makes sense in light of what Christ has done for me. I do feel a responsibility to speak truth and point people to God’s Word, but the deeper motivation is gratitude and love. I believe God is still working in me: “He who has begun a good work… will complete it” (Phil 1:6). I also know that any increase I have is not because I am impressive; “God gave the increase” (1 Cor 3:6–7). That keeps me grounded. True growth is not self-worship; it is dependence, abiding in Christ like a branch in the vine, because “without Me you can do nothing” (John 15:1–5).
True spiritual growth also shows up in fruit, not just talk. If the Holy Spirit is truly at work in me, He will produce what I cannot consistently produce on my own: “love, joy, peace… kindness… self-control” (Gal 5:22–23). That fruit does not appear overnight, and I still stumble at times, but the direction of my life changes. I increasingly want to please the Lord, not myself. I increasingly want truth, not excuses. I increasingly want to “speak the truth in love” and “grow up in all things into Him… Christ” (Eph 4:15). I increasingly want to put off the old patterns and put on the new life, “put off… the old man… be renewed… and… put on the new man” (Eph 4:22–24; Col 3:9–10). That is not perfection in a moment; it is progress in a direction.
Finally, true spiritual growth looks like living with eternity in view. I still live in this world, but I do not want the world to rule me. My heart is learning to live for what lasts, not what flashes. I press forward, like Paul described: “forgetting those things which are behind… I press toward the goal for the prize of the upward call of God in Christ Jesus” (Phil 3:13–14). The more I grow, the more I see that living for myself is a miserable cycle of chasing what never satisfies. But living by the Spirit produces steadiness, endurance, and hope (Rom 5:3–5; James 1:2–4). So, when I ask what true spiritual growth looks like in my life, I would say this: it is the Lord changing my will, renewing my mind, producing His fruit in me, and teaching me to live today with the end in mind, so that my life is not about what I can gain right now, but about faithfully walking with Christ and helping others see Him too.
