There’s a reason Jesus said,
Even the disciples, who had walked beside Him for years, weren’t ready for everything He wanted to reveal. Truth is not withheld because God is stingy; it’s withheld because He is merciful.
When Paul wrote to the Corinthians, he said,
In other words, they were loved, forgiven, and saved, but not yet mature. Their jealousy, comparison, and quarreling proved they were still living from the old self, not the new life of the Spirit.
We don’t fault a baby for needing milk. We don’t expect a toddler to carry the weight of an adult’s responsibility. Growth takes time, and so does spiritual maturity. God doesn’t shame us for being young in faith. He keeps feeding us what our hearts can handle, stretching us slowly and lovingly until we can digest more.
When my children were small, they wanted to help with everything: cooking, mowing, driving. They weren’t ready yet. Their desire was good, but they needed time to grow into strength, wisdom, and steadiness. I think God smiles at our eagerness the same way. He’s not frustrated by our weakness. He’s forming us through it.
The book of Hebrews says,
Maturity doesn’t come through information but through transformation. We learn discernment “by reason of use.” We grow by putting truth into practice again and again until our senses are trained to see things as God sees them.
But spiritual maturity is not about earning more truth; it’s about learning to receive it. The more we trust the Father’s heart, the more truth we can bear. Truth is not something we study to master; it’s a Person we grow to know. As we rest in the love of Christ, the Spirit unveils more of Him to us. The Spirit does not give us data about Jesus; He reveals Jesus Himself, alive within us. The more we awaken to that union, the more we discover that everything we need is already found in Him. We are not climbing toward some higher class of Christian life; we are growing in awareness of the life we already share with Him. Grace does not fade as we mature; it deepens. The same love that first held us still holds us when we grow, but we experience it with greater surrender and joy.
Truth isn’t mature in us until it’s visible in the way we live.
God’s classroom for maturity is rarely comfortable. He teaches us through delays, detours, and disappointments. When things don’t happen on our schedule, He’s developing steadiness in us. When people fail us, He’s teaching us mercy. When we face loss, He’s inviting us to lean into His strength instead of our own.
Every stage of spiritual growth has its purpose. Milk when we’re fragile. Solid food when we have matured. Even when we think we’re ready for more, God knows what we can truly carry. Sometimes, He waits to give a deeper understanding until life has softened us enough to receive it.
Think of how many truths once frightened or confused you but later became the very anchor of your faith. You weren’t resisting truth; you were being prepared for it. God was enlarging your heart so it could hold more of His wisdom and His love.
And perhaps this is one of the great mercies of heaven, that God rarely tells us everything at once. Imagine if He did. Imagine if we could see the whole journey of sanctification in a single glance. We would be paralyzed by fear or pride, either shrinking from the road ahead or boasting in what we had not yet walked. So He reveals truth in fragments, giving us enough light for the next step, trusting that we will come to trust Him more than the map.
Maturity, then, is learning to want what God wants, even when it crosses our own desires. It is the steady surrender that happens when love has burned away self-will. It’s the slow, quiet miracle of becoming content with mystery, knowing that God’s silence is as purposeful as His speech.
Think of the adamant spiritual leader who insists he already knows and criticizes everyone else for changing. He’s certain of his understanding, and he boasts that he “knows he knows.” Yet the tragedy of such certainty is that it shuts the door to growth. The Bible is full of stories showing that every follower of God is called to grow, to change, to see more than they once could. We are all being transformed, degree by degree, from glory to glory. If we stop learning, we begin to harden. If we think we’ve arrived, we drift into pride without realizing it. The truth is, we don’t even understand what we understand. Our insights are small pieces of a greater whole, and the more we know God, the more we realize how much we still need His light. To think we have arrived and already know is a quiet kind of laziness. It is not the laziness of idleness, but of a heart that no longer listens. Pride hides behind the appearance of certainty, but it closes the door to growth. The moment we stop being teachable, we stop growing. True maturity stays humble enough to keep learning, to admit that there is still more to see, more to surrender, more to understand.
Sometimes I get angry with myself because I was so sure I was right, only to look back and realize how foolish I had been. I see moments when I followed the spiritual crowd rather than the Spirit of truth. My opinions fit with those that I admired at the time. They seemed successful, so they must have been right. God was blessing them right. They said at least some of what I already believed, how I was raised, what I thought must be right. But even that is part of growing. God allows us to see the places where we wandered so that humility can take root. The point is not to live in regret, but to let mercy teach us to listen better the next time.
This is why grace never leaves us. The Spirit of truth walks with us, revealing more of Jesus as our hearts become ready to receive Him. God’s goal is not to make us smarter; it is to make us surer of His love. Every time He unveils more truth, it’s to deepen our trust, not inflate our pride. We grow as we learn to live from union with Christ instead of striving to impress Him. We mature when we realize that the same grace that saved us is the grace that sustains and grows us.
Think of how you would ruin your life if you decided that you already knew it all and didn’t need to grow. The Bible is full of reminders that we must grow, even when there are things in our lives we are not yet ready for. The greatest danger of pride is that it blinds us to our own lack. We cannot see what we do not know. Growth begins with humility, the willingness to admit that there are still things God wants to show us, corners of our heart He wants to heal, truths He wants to teach, and grace He wants to give.
We are all growing children in the Father’s house. And the good news is that He’s patient. He never rushes the process or shames us for being where we are. He keeps inviting us forward. From milk to meat. From confusion to clarity. From fear to faith.
The same God who started our growth will finish it. Until then, He keeps feeding us, one spoonful of grace at a time, until we’re strong enough to digest the deeper things of His heart.
And when we finally stand before Him, the truths that once overwhelmed us will feel as natural as breathing. For now, He gives us the simple task of growing quietly, loving deeply, and trusting wholly, the true marks of those who are finally becoming mature in Christ.
