From the very beginning, God created restoration as part of our souls and bodies. Practices of trust, surrender, and relational faith are associated with measurable biological changes. Just as grace restores our souls, our brains themselves are built to participate in healing, growth, and restoration. Neuroscience now calls this neuroplasticity. The Bible has been calling it renewal all along.

Neuroplasticity simply means your brain can change. It can be renewed, rewired, and restored. That lines up beautifully with what the Bible has always promised: transformation is possible. When we surrender to God, it doesn’t just shape our beliefs—it biologically changes us.

Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect. Romans 12:2.

Food, movement, noises, smells, bacteria, hormones, love and conflict all influence how our brain decides to act. Your body matters.

Here’s where love becomes a really big deal. Not transactional love, not fear-based love, not love you have to earn. Secure attachment kind of love.

Secure attachment strengthens the brain. When love is responsive and trustworthy, it builds healthy neural pathways, especially in areas connected to emotional regulation, decision-making, and connection. Feeling safe reduces chronic stress and helps regulate cortisol levels and reduces harmful effects of chronic stress. Secure attachment also encourages exploration and learning, activating parts of the brain responsible for memory, problem-solving, and wisdom.

(I want more of this, please!)

Consider this twist. Jesus changed his disciples’ brains by offering a new life within the context of God’s trustworthy love. From what we now understand about learning, attachment, and neuroplasticity, it’s reasonable to say their lives–and therefore their brain–were profoundly shaped. Imagine those neural connections being formed in the three years they learned from Jesus! They were stretched. They learned the hard way. They were formed inside secure attachment kind of love.

Our brains develop optimally inside love that can be trusted.

Too many of you know the results inside of you from receiving untrustworthy love. Broken systems of love distort how we see God.

You belong to God. (Read more about the depth of this truth at The Beautiful Security of Belonging to God.)

When we surrender to God, we begin brain restoration anchored in love.

Our brains shift out of constant stress and survival mode. Safety allows the brain to heal from fear and shame. Spiritually and biologically, trusting God helps regulate emotions, moving us from fear, rage, or shutdown into peace and connection.

The vagus nerve plays a key role among several systems involved in emotional regulation. You have already felt this even if you haven’t named it yet.

The vagus nerve runs from the brainstem through the neck, past the heart and lungs, and to the gut. It regulates heart rate, breathing, digestion, and emotional balance. It’s like a superhighway between the brain and the gut.

That’s why scientists sometimes call the gut a “second brain.” Your gut, heart, and brain are in constant conversation on this superhighway. You already know this. You’ve felt it when you’ve thought with your gut. When you feel stressed or anxious, it is in your gut. When you make a big decision, you make it in your gut.

Spiritually and biologically, trusting God helps regulate emotions. Instead of being stuck in fear, rage, or shame, surrender opens us to peace, relational connection, and healthier emotional patterns. Experiencing grace gradually improves vagal nerve tone, which leads to improved autonomic balance. Experiencing grace–receiving love and not judgment–activates this calming system, helping your body move from fight/flight into rest and connection.

Experiences of trust are reflected in the nervous system, including vagal regulation. Trust is evidence-based. Trust builds trust. Trust develops under the influence of secure attachment love. Vagus nerve tone improves as you experience loving and trusting relationships.

Insecure relationships weaken vagal tone. You don’t eat right, you are anxious, you feel the trepidation in your gut. Right? The good news is that this is reversible!

When you say you’re taking time for your heart to heal, you are allowing your nervous system to return to balance, you are “slowing down that superhighway.” This is restoration, even for our bodies.

The Bible says, Above all else, guard your heart, for everything you do flows from it. Proverbs 4:23. Or I have hidden your word in my heart that I might not sin against you. Psalm 119:11. Do you see how this works?! This is how our bodies work before science told us so.

Life has broken you. Life has severed attachments inside you. Anxiety left untreated grows stronger because it forms neural pathways. Worry is a well-worn pathway but it works for us. Worry feels responsible.

But anxiety, worry, and fear strain the nervous system. They deepen ruts in the brain. And yet–even here–your body was designed to heal and reattach.

So when we say our brains are designed for redemption and restoration, we’re saying this: God wove into us the very capacity to heal. What has been broken can be rewired. What has been hijacked by fear or shame can be restored to love and connection.

The bad news is that your brain has been shaped by sin and by forces outside your control. The good news is that you can intentionally harness your neuroplasticity by focusing your attention and making proper choices. Your brain is always under development, a process that never stops and in which you can actively participate. You have the God-given authority to lead your brain.

These verses may make more sense now. And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice—the kind he will find acceptable. This is truly the way to worship him. Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect. Romans 12:1-2.

Every choice you make is shaping your brain. Formation takes time. Transformation is possible. God didn’t design your brain to stay stuck. God designed it for restoration.
