Praise Is Spiritual Warfare: What David Knew About Worship, Neuroscience, and Renewing Your Mind

Bonus Episode Season 2, Episode 1 Show Notes Why can anxiety make the stomach hurt? Why do some people feel nauseated, lose their appetite, experience digestive changes, or feel a pit in their stomach when they are stressed? In this episode of The Christian Mind Reset, Dr. April Joy explores the fascinating connection between anxiety, the gut-brain axis, the nervous system, and gastrointestinal symptoms—and brings the conversation back to one of Scripture's most familiar passages: Psalm 23. As a board-certified psychiatric mental health nurse practitioner, psychotherapist, Bible teacher, and student of neuroscience, Dr. April Joy explains how the brain and gut are constantly communicating through a complex bidirectional system involving the central nervous system, enteric nervous system, autonomic nervous system, stress-response pathways, immune and endocrine signaling, the vagus nerve, and the gut microbiome. She explains why anxiety is not experienced only as worried thoughts. Stress can also show up physically through nausea, appetite changes, abdominal discomfort, diarrhea, constipation, muscle tension, changes in breathing, and other bodily sensations. The episode also explores interoception, the brain’s ability to sense and interpret signals coming from inside the body, and how physical sensations can sometimes become part of an anxiety cycle. A person notices a racing heart, tight stomach, nausea, or another uncomfortable sensation, interprets it as threatening, becomes more anxious, and then experiences even stronger physical sensations. Dr. April Joy also discusses emerging research on the gut microbiome and brain, including why intriguing findings from animal studies should not automatically be interpreted as evidence that gut bacteria cause human psychiatric disorders. But the heart of this episode returns to Psalm 23:5: “You prepare a table before me in the presence of my enemies.” Dr. April Joy considers this verse through the lens of anxiety and the nervous system. The table is prepared while the enemies are still present. The circumstances have not necessarily disappeared, yet David describes the Shepherd's provision and presence in the middle of them. For someone whose anxiety makes eating difficult, that image carries special meaning. The episode connects this truth with Jesus calming the storm, Isaiah 26:3, Philippians 4:6, Matthew 6:34, taking thoughts captive, biblical meditation, neuroplasticity, and prayer. It also examines an fMRI study of committed Christians that found personal, improvised prayer recruited brain regions involved in social cognition, offering an interesting neuroscientific window into the relational experience of prayer without using neuroscience to prove theological claims. Listeners will also learn about research in people with generalized anxiety disorder showing that 91.4% of the worry predictions recorded in one study did not come true, illustrating how often anxiety can pull the mind into feared futures that never arrive. In This Episode Dr. April Joy discusses: * The gut-brain axis and anxiety * Why anxiety can cause nausea and loss of appetite * The enteric nervous system or “second brain” * The vagus nerve and parasympathetic nervous system * Stress, the HPA axis, and gastrointestinal symptoms * Interoception and the anxiety-sensation cycle * Serotonin and the gastrointestinal system * The gut microbiome and mental health research * Why animal microbiome studies require careful interpretation * Neuroplasticity and repeated patterns of thinking * What neuroscience can—and cannot—tell Christians about prayer * Psalm 23 and God’s presence during anxiety * Why worry often pulls the mind into the future * Scripture-based breath prayer using Psalm 23 * Biblical declarations for anxiety, fear, and uncertainty The episode closes with declarations from Psalm 23, a guided prayer, and a reminder that Christians can pray, renew their minds, and trust God while also receiving appropriate me

Episode 29, Season 1 In the final episode of Season One of The Christian Mind Reset, Dr. April Joy brings together the neuroscience, psychology, and biblical practices explored throughout the past 28 days and looks at what it actually means to renew the mind. The brain is capable of change. What people repeatedly think about, focus on, practice, and return to can strengthen patterns in the brain and make certain responses more automatic over time. But Romans 12:2 is not simply a lesson in neuroplasticity, and Christian renewal cannot be reduced to “rewiring the brain.” So what does renewal actually look like? Dr. April Joy explores that question through Scripture and also through the life of Jesus. If Christians are called to have the mind of Christ and to walk as He walked, it matters how Jesus actually lived. Throughout the Gospels, Jesus prayed, fasted, knew and spoke Scripture, withdrew to be alone with the Father, gave thanks, gathered with others, lived in community, served, showed compassion, and remained dependent upon and obedient to the Father. This episode looks at some of those practices alongside what neuroscience and psychology have found about attention, repetition, meditation, self-talk, gratitude, emotional regulation, relationships, and repeated behavior. Dr. April Joy also returns to the biblical language of putting off the old self and putting on the new. Colossians 3 does not simply tell believers what to stop doing. It tells them what to put on instead: compassion, kindness, humility, gentleness, patience, forgiveness, love, peace, and gratitude. This is where Batman comes in. Research sometimes referred to as the “Batman Effect” found that young children who approached a difficult task from the perspective of an exemplar character, such as Batman, showed greater perseverance and were better able to resist distraction. Researchers have studied this in the context of self-distancing, the ability to create some psychological distance from an immediate thought, feeling, or impulse. Dr. April Joy looks at what this research can teach us about pausing long enough to consider a different response and then connects it to the biblical picture of putting off and putting on. For the Christian, this is obviously not about pretending to be Batman, or even pretending to be Jesus. It is about remembering who Scripture says believers are, what they are called to put off, what they are called to put on, and then practicing a response consistent with that truth. The episode also explores why thoughts and feelings are important without automatically treating them as facts, how repeated responses can become more automatic over time, why gratitude is not the same as denying pain, the importance of Christian community, and how prayer, fasting, Scripture, meditation, and speaking truth can become regular rhythms of renewal. Neuroscience can help explain mechanisms involved in attention, learning, memory, emotional regulation, repetition, and behavior. It can study what happens in the brain during practices such as meditation and prayer. But it cannot measure the work of the Holy Spirit, tell people the meaning of their suffering, or explain away spiritual transformation as brain activity. Ultimately, Christian renewal is not about becoming better at optimizing the brain. It is about becoming more like Christ. And that brings the episode back to one of the most important practices of renewal: abiding. Jesus said, “Apart from me you can do nothing.” The goal is not to manufacture renewal or the fruit of the Spirit by trying harder. Fruit grows from connection to the source. Christians participate through obedience, practice, prayer, Scripture, community, and continually bringing the mind back to truth, but Jesus remains the source.

Episode 28, Season 1 Show Notes What happens in the mind and brain when we have hope? Why can hope change the way we experience the present, even when our circumstances have not changed? And how is biblical hope different from optimism, wishful thinking, or simply trying to “think positive”? In Episode 28 of The Christian Mind Reset, Dr. April Joy explores the psychology and neuroscience of hope alongside the biblical understanding of what it means to place our hope in God. The episode begins with C. R. Snyder’s Hope Theory, which describes hope through two important processes: agency, our perceived ability to move toward a goal, and pathways, our ability to identify ways forward when obstacles arise. We review research exploring the relationship between hope, anxiety, brain function, and meaning in life. But psychology and neuroscience only take us so far. The Bible presents a deeper picture of hope. Biblical hope is not pretending that everything will work out the way we want. It is not denial of suffering, and it is not positive thinking with a Christian vocabulary. Biblical hope is confidence in God's character, promises, and faithfulness, even when the outcome is still unknown. Through Psalm 130, Romans 8, and Hebrews 6:19, we explore what it means to hope while waiting, suffering, grieving, and facing an uncertain future. We also look at the lives of Abraham, David, Joseph, Jeremiah, Job, and Paul, people who experienced seasons when God’s promises and their present circumstances did not appear to match. Their stories remind us that hope does not require us to ignore what is happening around us. Hope does not mean everything around you is steady. Biblical hope gives your soul something steady to hold onto when everything else is not. In the final portion of the episode, we move from understanding hope to practicing hope through Scripture-based declarations, grounding, reflection, and prayer. The goal is not simply to learn something about hope, but to begin training our minds to remember where our hope is anchored.

Episode 27, Season 1 Show Notes Can gratitude really change your brain? Why does the Bible repeatedly tell us to “give thanks,” while also warning us against grumbling? In this episode of The Christian Mind Reset, we explore what psychology, neuroscience, and Scripture reveal about gratitude, complaining, and the way repeated thought patterns shape our minds. Together, we’ll examine research on gratitude, neuroplasticity, negativity bias, emotional regulation, and stress while walking through some of the Bible’s richest passages on thanksgiving. We’ll look at David in the Psalms, Israel in the wilderness, and the moments Jesus gave thanks—even in the face of rejection, grief, scarcity, and the cross. You’ll discover why biblical gratitude isn’t pretending life is easy or denying suffering. Instead, it’s intentionally remembering God’s faithfulness and bringing your attention back to what is still true, still good, and still worthy of praise. In this episode, we discuss: * What gratitude does in the brain * The neuroscience of neuroplasticity and negativity bias * Healthy lament versus chronic complaining * Why God repeatedly commands thanksgiving * What Jesus thanked the Father for * Psalm 107 and the power of remembering God’s faithfulness * Practical ways to cultivate biblical gratitude in everyday life If you’re struggling with anxiety, discouragement, stress, or simply want to renew your mind through Scripture, this episode will encourage you to see gratitude as more than a feeling; it is a spiritual discipline that shapes both the heart and the mind.

Episode 26, Season 1 Show Notes What does it mean to “strengthen yourself in the Lord,” and what can David’s life teach us about persevering through suffering? In this episode of The Christian Mind Reset, Dr. April Joy explores perseverance through the life of David, with a particular focus on 1 Samuel 30:6 and the Psalms. Throughout David’s life, readers see a consistent pattern of returning to God through prayer, worship, gratitude, remembering God’s faithfulness, and fixing his hope on the Lord, even in seasons of fear, betrayal, grief, and waiting. Drawing from Scripture alongside current research in psychology and neuroscience, this episode examines how practices woven throughout David’s life align with what is known about hope, attention, memory, metacognition, worship, and emotional resilience. Rather than placing confidence in psychological techniques, the episode points listeners back to the biblical truth that lasting perseverance is found by continually returning to God, who is the source of our hope and strength. Whether listeners are walking through disappointment, suffering, uncertainty, or simply finding it difficult to keep going, this episode offers biblical encouragement and practical insight for persevering while keeping their eyes fixed on Christ.
