Note: This episode was originally published on October 8, 2025 and was one of our most popular conversations over the last 12 months. We're currently taking a summer break for the month of July, but we will be back with new episodes starting on August 5th.
Dr. Mark Turman sits down with world-renowned scientist Dr. James Tour for a conversation that bridges faith and science in remarkable ways. Dr. Tour shares his story of coming to faith in Jesus—how a secular Jewish student became a passionate follower of Christ—and what that journey has taught him about truth, reason, and grace.
Together, they talk about the mysteries of life’s origin, the promises and pitfalls of artificial intelligence, and how Christian hospitality can open hearts to the gospel. Dr. Tour also reflects on his pioneering work in nanotechnology at Rice University and offers wisdom for students and parents seeking to hold onto faith in the world of higher education.
It’s a thoughtful, hope-filled dialogue about what it means to follow Jesus with both mind and heart.
