Chasing Proof, Finding Faith – Dr. Tom Rudelius’ Story

What happens when the pursuit of intellectual certainty leads not to clarity, but to doubt, and doubt, in time, leads back to faith?  Jeffrey Geibel, a seasoned mathematics educator and former skeptic, shares a journey that challenges assumptions about belief, knowledge, and truth. Raised in a home where chaos, cultural Christianity, and moral contradictions shaped his early view of faith, Jeff set out to find truth through reason and lived experience. Though once deeply involved in church and sincere in his belief, growing disillusionment with theological inconsistencies and a reliance on subjective experiences ultimately led him to atheism, then to radical agnosticism, questioning whether anything could truly be known at all. The turning point came unexpectedly, in a graduate-level geometry class.  Guest Bio: Jeffrey Geibel is a veteran high school mathematics teacher with two decades of experience in public education. He holds a master’s degree in mathematics and brings a deep appreciation for critical thinking, logic, and analytical inquiry to both his profession and personal life. Outside the classroom, Jeff is a dedicated husband and father of nine, with a passion for exploring the intersections of faith, reason, and human experience. His journey through skepticism, agnosticism, and ultimately back to belief reflects a thoughtful engagement with both intellectual honesty and existential meaning.

Show Notes: Why do people believe in God, or reject Him altogether? In this compelling episode, Dr. Jay Medenwaldt shares his intellectual and spiritual journey from atheism to belief. A social psychologist with a PhD from Baylor and a current professor at Northwestern College, Jay approached religion from a purely academic lens, interested in why people believed in things he once viewed as clearly false. But, in an effort to avoid confirmation bias and stay true to his role as a researcher, Jay began examining both sides of the argument. To his surprise, the rational and historical case for Christianity was stronger than he expected. Guest Bio: Dr. Jay Medenwaldt, a former Air Force behavioral scientist with nine years of service, including teaching psychology courses at the Air Force Academy and conducting research. Dr. Medenwaldt holds a doctorate in social psychology from Baylor University, with a focus on the psychology of religion and virtue.

Laura Zifer Powell seemed to be doing everything right. A top-tier student and Division I athlete at Duke University, she was driven, disciplined, and outwardly successful. But beneath the surface, something was missing. The more she achieved, the emptier she felt. And when a health crisis brought everything to a halt, the questions she had avoided for years finally caught up with her: What is all this for? What’s the point of being good if it still doesn’t satisfy? In this candid conversation, Laura shares her journey from moral pragmatist and religious skeptic to a confident follower of Christ. She opens up about the moment everything changed—a late-night plea to a God she wasn’t sure existed, and the quiet unraveling that followed. If you've ever asked, “Is this all there is?” or wrestled with the gap between outward success and inward emptiness, Laura’s story offers more than answers—it offers hope.   Guest Bio: Laura Zifer Powell is a Christian apologist, writer, and speaker. She is the founder of An Affair with Reason and co-host of the Knight and Rose Show podcast. She graduated from Duke University with a bachelor’s in public policy, earned her master’s degree from Denver Seminary, and is currently working on her Doctor of Ministry in Public Theology from Birmingham Theological Seminary. She has ministered in over thirty countries on five continents and has seen first-hand how false worldviews harm and destroy God’s image bearers, while the Christian worldview leads people and societies toward human flourishing. As an apologist, she shares evidence for the biblical worldview and discusses how our worldview ought to impact every area of life, from our relationships to our public policy and economics.
