We often talk about spiritual growth as if the ultimate goal is personal self-improvement. We read our Bibles, attend church, and try to make good moral choices, hoping to eventually become slightly better, more polished versions of ourselves. But when Jesus talked about spiritual growth, He didn’t point to self-improvement. He pointed to a harvest.
In Luke chapter 8, Jesus shares the Parable of the Sower. He describes a farmer scattering seed across four different types of soil. It is crucial to realize that the seed—which Jesus says is the Word of God—is exactly the same in every single scenario. The only variable, the only thing that determines whether life springs up or dies out, is the condition of the dirt. The soil represents the condition of the heart.
Before we can understand the good soil, we have to look honestly at how the dirt gets ruined.
First, Jesus describes the path. This represents a completely hardened heart. What packs the soil down so tight that the Word of God just bounces off? Sometimes it is the heavy boots of deep trauma, abuse, pain, or addiction that cause people to build massive protective walls just to survive. Other times, it is our own religious traditions, a lack of sound theology, or outright idolatry. We essentially pave over the dirt with our pride because we think we already have all the answers.
Second, He points to the rocky ground. The seed actually breaks the surface here, and the initial reaction is pure joy! People love the idea of freedom and healing. But underneath a very thin, superficial layer of emotional topsoil is a bedrock of solid stone. When life gets hard, or when following Jesus requires laying down our pride, it simply costs too much. The roots can’t go deep because that underlying rock of self-will was never surrendered.
Third, Jesus talks about the thorns. This is the crowded heart, and it is something we see so often in our churches and Christian homes. It looks like having a form of religion and understanding, but still being completely driven by an appetite for the flesh. It is syncretism—blending cultural tolerance and accepting everything society celebrates while trying to keep Jesus as a nice accessory. The thorns of distraction, wealth, and worldly pleasures eventually choke the life out of the plant.
In all three of these failures, the root problem is exactly the same: pride and a heart that desperately wants to remain on its own throne.
So, what makes the good soil “good”?
Jesus says it is an honest and good heart that holds the Word fast and bears fruit with patience. The absolute antidote to pride and idolatry is humility. Good soil represents a total release of control over your own life. It is a willingness to be transformed by the renewing of your mind, a reliance on the counsel of the Holy Spirit, and daily obedience to the Word. Good soil doesn’t try to control the seed; it simply yields to it.
But here is the catch. When that good soil finally yields a healthy tree, what is the fruit actually for?
If you look at an apple tree, it doesn’t eat its own apples. The fruit doesn’t exist for the benefit of the tree itself. It doens’t even grow for our own personal pleasure we find in eating the fruit. It’s grown to make more trees. Orchards even.
The evidence of a genuinely healthy Christian isn’t just that they have great inward character, though that inward transformation is absolutely necessary. The true, biblical evidence of a healthy Christian is multiplication. It is gospel saturation. Our inward character makes the gospel attractive. Our outward actions make the gospel tangible. And our active multiplication—seeing people saved and sharing the good news that changed us—ensures the seed / fruit of the Gospel keeps spreading.
If the seed stops with us—if we enjoy the shade of our own tree but never drop any seeds for others—we have completely missed the entire point of the harvest.
This is exactly why I recently created a hat that connects directly to the heart of Luke 8:15. It simply says, “Jesus Loves You.” It might seem like a small thing, but it is an incredibly effective way to continue bearing fruit. It serves as an easy, everyday conversation starter. It keeps the gospel on my mind, and it is a tool to ensure I am always ready to share the hope that transformed my life. Pick up yours by clicking on “Jesus Loves You.”
I want to challenge you as you are reading this right now: set a concrete goal to share the gospel often. Don’t wait for the perfectly scripted moment to drop into your lap. Step out and create those moments. Whether it’s wearing something that sparks a question, asking a coworker how you can pray for them, or simply being bold enough to share your story, make multiplication a daily habit.
At the end of the day, our spiritual lives are never just about our own growth. They are about the magnification of God’s glory and His power to transform. Think about a massive, life-giving, fruit-bearing tree. When you see a tree like that, you don’t praise the dirt. The dirt didn’t create the seed. The dirt didn’t make the rain fall, and it certainly didn’t command the sun to shine. The soil is just the canvas; God is the artist, and He gets all the glory. As you share you will face all types of dirt. Trust the Lord to do the work, just share the Gospel.
My prayer for you is that one day, God gives you the blessing to look back on a lifelong, faithful pursuit of bearing good fruit. And when you do, I pray you don’t just see a single healthy tree, but a massive orchard—one that is still expanding, still growing, and still bearing good fruit for His glory.
Questions for Group Discussion:
- When you consider the “thorns” we discussed—like syncretism, the appetite for comfort, or cultural tolerance—which ones do you feel are most actively trying to crowd out the truth in your own life right now?
- We talked about how an apple tree doesn’t eat its own apples, meaning our inward transformation is meant for an outward expression. Look honestly at the spiritual fruit in your life today: who is actually being nourished by it?
- What is one practical goal you can set this week to actively share the gospel and spark a conversation about Jesus in your everyday life?
