Rewiring the Brain from Anxiety to Joy - With Gratitude

Jun 28, 2026    Pastor Josh Hawkins

Why does God command us to praise and thank Him so often? Is He insecure, or is there something deeper at play?

In this episode of our series, "Delighting in a Delightful God," we dive into the practical, brain-changing power of gratitude. Drawing from the brilliant insights of C.S. Lewis, we discover that God’s commands aren't for His ego—they are entirely for our benefit.

As a speaker with a background in neuroscience and trauma, I walk you through the incredible reality of how praise and thankfulness literally suck worry and cortisol out of our flesh, flooding our bodies with dopamine and serotonin. Gratitude is a shield on our hearts that guards us against anxiety, resentment, and the lies of the enemy.

If you are walking through a difficult season, feeling anxious, or wondering how to give thanks in "all circumstances," this sermon is for you. Learn how a simple practice of gratitude can physically rewire your brain from a worry circuit to a rejoicing circuit.
