Desire is a curious thing.

In fact, that’s the exact phrase the author of a recent article on addiction used to summarize what secular neuroscience has uncovered about why people desire things that don’t make them happy. It’s an article that offers a lot of insight into brain function—what the author calls the uncoupling of “wanting” from “liking.” And for the most part, it does a helpful job explaining how the bodily execution of dopamine-driven processes can go rogue, turning normal desires into unmanageable cravings.

But as I read the piece, I kept thinking: This is only half the story. The science is helpful, but it’s incomplete; it offers unique insight regarding a “what” and “how,” but not the “why.” And as a result, while informative, for the Christian it offers data but no hope. Furthermore, for those of us who walk with people through the trenches of addiction and compulsive reactivity, we know people need more than brain science. They need a theology of desire. They need good news.

So, let’s talk about that. Let’s talk about how what neuroscience observes about desire fits within a biblical worldview, and more importantly, how Scripture gives us a more hopeful and transformative answer to what addiction is—and what freedom looks like.

We Are Fearfully and Wonderfully Made

One of the most profound takeaways from neuroscience is how marvelously complex God’s design of the human body is, and this includes our brains. Psalm 139:14 puts it simply: “I praise you, for I am fearfully and wonderfully made.”

Neuroscience confirms what Scripture has said all along. We are designed with intricate mechanisms that motivate us toward action. The article explains the distinction between “wanting” and “liking,” noting that dopamine fuels our desire (the “want”), while pleasure circuits regulate our enjoyment (the “like”). In short, God wired the brain to help us pursue what we value. We see this as early as the Garden of Eden. 

We are constantly seeking after what we believe will satisfy us—whether that’s God or something else. What the article calls “incentive salience,” the Bible calls treasuring something in your heart (Matthew 6:21).

The Corruption of Desire: The Flesh and Total Depravity

The article describes the tragic reality that people can end up craving things they no longer enjoy—wanting without liking. This is most vividly seen in addiction, where someone keeps returning to alcohol, porn, food, or drugs, long after the pleasure is gone.

What they are describing here is the flesh in action. Galatians 5:17 says, “For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh.” This is Romans 7 lived out: “For I do not do what I want, but I do the very thing I hate” (v. 15).

The “wanting” system the article talks about? That’s simply the flesh being flesh. Sin is never satisfied (Proverbs 27:20), and it manifests itself in the inescapable pull toward destructive behaviors, even when we know they are bad for us.

The dopamine circuits may explain how this happens, but Scripture explains why. We were made to worship the Creator. When we worship something else, we become enslaved to it (Romans 1:24-25). Addiction is not primarily a disease or a neurological disorder; it’s disordered worship.

The Regeneration of the Heart: A New Birth and New Identity

Here’s where the secular narrative runs out of gas. The article explains why we are stuck in wanting without liking, but it offers no path to freedom. At best, it suggests coping strategies to manage the tension. But Scripture offers something better.

God gives His people new hearts (Ezekiel 36:26). At regeneration, God removes the heart of stone—the one enslaved to sinful cravings—and replaces it with a new heart that is “alive to God in Christ Jesus” (Romans 6:11). At salvation, God fundamentally changes the nature of the believer’s heart and mind. It is no longer only deceitful and desperately wicked (Jeremiah 17:9). It has been cleansed, made new, and sealed by the Holy Spirit (Ephesians 1:13-14). As such, the mind can now be renewed and better decisions made through the strength provided by God through the Holy Spirit (Romans 12:2). The ongoing battle against sin is living out the newness we now have within us. 

The Battle for the Mind: Rewiring Through Repetitive Biblical Thinking

The article describes something called “incentive sensitization,” where the brain’s wanting circuits get over-amplified. As a result, people keep going back to the same sin, even when they no longer like it.

But here’s the biblical reality: The mind can be renewed. And neuroplasticity—the brain’s God-given ability to rewire itself—is one of the ways that happens.

This is why the repetitive practice of truth-based thinking is so central to biblical counseling. As we fill our minds with the truth of God’s Word (Philippians 4:8), we quite literally create new neural pathways. The repetition of truth-centered thinking rewires both our brain and our behavior. What neuroscientists observe about “neurons that fire together, wire together” aligns with what Scripture commands: “Do not be conformed to this world, but be transformed by the renewal of your mind” (Romans 12:2).

As a result, as biblical counselors, we need to consistently providing resources and homework that is geared toward helping counseling redirect their thoughts to the places and spaces that will help them with this. Consider resources like this. 

False Worship vs. True Worship: The Core Issue

At its heart, addiction is not a brain issue. It’s a worship issue.

When the article describes someone compulsively returning to behaviors they hate, Scripture calls that bondage. Colossians 3:5 says, “Put to death therefore what is earthly in you…which is idolatry.”

The reason dopamine keeps firing long after liking has faded is that people are in bondage. Whether it’s the bottle, the pill, the screen, or the approval of others, we become what we worship and prioritize (Psalm 115:8). Only Jesus Christ can break those chains and offer freedom: “So if the Son sets you free, you will be free indeed” (John 8:36).

A Better Story: Redemption and Renewed Desire

The secular narrative of addiction ends in despair. At best, it offers techniques to manage your dopamine circuitry. But the biblical narrative ends in hope. God doesn’t just help you cope; He makes you new (2 Corinthians 5:17).

In Christ, we have the power to “say no to ungodliness and worldly passions” (Titus 2:12). The Spirit empowers new affections (Galatians 5:16-24). And over time, as our minds are renewed, even our brains follow suit—retrained to want what is good and holy.

The gospel offers a better story. It offers a new identity. It offers true freedom. And it offers the only real solution to the problem of disordered desire.
