Neuroscience and Fear: Biblical Declarations for Renewing the Mind

The Christian Mind Reset Daily Reset: Neuroscience and Fear

Fear to Faith: Biblical Declarations for Renewing the Mind

Fear is something every one of us experiences. Sometimes it serves a purpose. Sometimes it protects us. But sometimes fear keeps us living in imagined futures, rehearsing worst-case scenarios, and carrying burdens we were never meant to carry.

In today’s Daily Reset, Dr. April Joy explores the neuroscience of fear, the psychology of worry, and what Scripture teaches about trusting God in uncertain seasons. Together we’ll look at how the brain responds to perceived threats, why fear often disguises itself as wisdom, and how God’s presence calms both the soul and the nervous system.

Using Psalm 27, Isaiah 41, Matthew 6, and John 16, we’ll learn that the antidote to fear is not certainty about the future, but confidence in the God who holds the future.
