The science behind fear with Dr. Fuz Rana & Faith vs fear

Today on Karl and Crew, we continued our weekly theme, “The Anxious Generation,” focusing on how fear can rewire the brain. We had Dr. Fuz Rana, the President, CEO, and Senior Scholar at Reasons to Believe, as our guest. He discussed how God designed our brains to respond to fear and offered hope through His truth and the work of the Holy Spirit. Additionally, Dr. John Mabus, Associate Professor and Program Head of Pastoral Studies at Moody Bible Institute, joined us to discuss how fear affects everyone and how bringing our fears to God helps us respond with courage in both everyday situations and life’s greatest challenges. Dr. Erwin Lutzer unpacked how Scripture renews our thinking and helps us keep our focus on Christ. Dr. Lutzer is Pastor Emeritus of Moody Church and author of “Cries from the Cross.” You can listen to the highlights from today’s program on the Karl and Crew Showcast.
