What if belief in God isn’t opposed to reason, but demanded by it?

Olivier Bonnassies, co-author of God, the Science, the Evidence: The Dawn of a Revolution, was once convinced that Christianity was irrational and that science explained everything, but he began to question his assumptions about reality, truth, and the origins of the universe. Through years of study in both science and theology, Olivier discovered that the evidence, from cosmology, philosophy, morality, and even history, points unmistakably toward a transcendent Creator. 

Together, Jana and Olivier explore:

Guest Bio:

Olivier Bonnassies is a French engineer, entrepreneur, and author with a background in both science and theology. Educated at the prestigious École Polytechnique in Paris, he spent years building successful companies before turning his attention to life’s deepest questions. Once an agnostic, convinced that belief in God was irrational, Olivier embarked on a personal investigation that led him to faith in Christ. He is co-author, with Michel-Yves Bolloré, of God, the Science, the Evidence: The Dawn of a Revolution, a bestselling book in Europe (over 400,000 copies sold) now launching in the U.S. Through his research and writing, Olivier argues that the convergence of science, philosophy, and history reveals a compelling case for God’s existence.

Where do we find real love, the kind that fills our souls and heals our brokenness? Is it through politics, psychology, or self-help? Or is it found in a Person? 

British journalist Heather Tomlinson shares her remarkable journey from a secular liberal worldview to a life transformed by Jesus Christ. Once convinced that human progress and political reform could heal the world, Heather found those paths empty. Her search for meaning led her through science, psychology, and even spirituality in Buddhism and Wicca—until she encountered the love of Christ through the Gospels.

Heather’s story reveals that faith in Jesus doesn’t just inform ideas—it reorders life itself: how we see people, how we approach suffering, and how we understand love.

Guest Bio:

Heather Tomlinson is a British journalist and writer who spent the early part of her career working for national newspapers in the UK, including The Guardian. Trained in molecular biology, she began her career reporting on industry and finance before moving into psychology and mental health. A one-time secular liberal, Heather’s pursuit of truth led her through science, politics, and spirituality until she found the love and reality of Jesus Christ. Today, she writes for Christian publications and serves in pastoral care, helping others discover faith and healing through God’s love.

Few questions weigh heavier on the human heart than death. Is there anything beyond this life? How do we face death without fear?

Dr. Stephen Iacoboni has wrestled with these questions every day for more than forty years as a medical oncologist. Once a committed scientific atheist, he sought answers in medicine, science, and humanism—only to find them insufficient in the face of mortality. Through the witness of his patients and the growing cracks in naturalistic explanations, Dr. Iacoboni came to embrace faith in God, discovering a hope that transforms both life and death.

In this conversation, he shares his journey from childhood faith to scientific atheism, through years of treating patients at death’s door, to finally returning to belief in Jesus Christ. Along the way, he examines the failures of naturalism, the role of science, and the undeniable human longing for meaning that points to something greater.

Guest Bio:

Dr. Stephen J. Iacoboni is a veteran oncologist, author, and speaker whose medical career spans more than forty years. Trained during an era dominated by scientific materialism, he once embraced an atheistic worldview. But through decades of walking with cancer patients in their deepest suffering, he rediscovered the reality of the human soul and the hope of faith. He is the author of The Undying Soul: A Cancer Doctor’s Discovery and Telos: The Scientific Basis for a Life of Purpose, where he shares both his personal journey from atheism to faith and his case for meaning and design in life. Today, Dr. Iacoboni continues to write and speak on the intersection of science, medicine, and spirituality, encouraging both doctors and skeptics to see beyond a purely mechanistic view of life.

What happens when the “certainty” of atheism collides with evidence pointing to something more?

Caleb Ball’s (YouTube’s Aspiring Christian Channel) story begins in small-town Pennsylvania, where childhood faith gave way to mocking Christianity and embracing naturalism. For six years, he lived as a convinced atheist, creating YouTube content ridiculing God, convinced that science had all the answers. But one book, on quantum physics and consciousness, began to dismantle his worldview, forcing him to ask deeper questions about truth, meaning, and the existence of God.

Guest Bio:

Caleb Ball is a former atheist turned passionate Christian communicator. Once a vocal critic of Christianity, known online as “Crazy Caleb” during his atheist YouTube years, he now uses his platform to share testimonies of skeptics who found faith in Jesus. Through his YouTube channel Aspiring Christian, he curates conversion stories and apologetics content to help others wrestle honestly with life’s biggest questions. Caleb holds a degree in history and is pursuing a Master’s in Biblical Studies at Colorado Christian University. He and his wife live in Montana, where they are active in their local church and community.

Jason Holloway grew up in a small, conservative church where faith seemed simple—until his honest questions about suffering, contradictions, and the Bible met unsatisfying answers. At 18, a conversation with a trusted professor left him believing he lacked “enough faith,” prompting him to walk away from Christianity for the next 25 years.

In that time, Jason explored atheism, agnosticism, Buddhism, and nearly every “ism” he could find, searching for meaning and truth. Eventually, he returned to the Bible—not just as literal text, but as boundless truth, rich with meaning, depth, and beauty.

Jason Holloway is a creative and strategy director in marketing and advertising, and co-host of The Boundless Bible podcast. Raised in a Christian home, Jason left the faith for over two decades., exploring philosophy, psychology, world religions, and secular worldviews in search of truth. Jason now shares his story to encourage skeptics and believers alike to ask hard questions and discover the richness of God’s Word.

Dr. Michael Egnor spent decades trusting science to answer life’s deepest questions. As a neurosurgeon and professor, he believed the brain held the key to understanding everything — including who we are. But over time, he encountered things science couldn’t explain: children thriving with missing brain structures, moral truths that couldn’t be reduced to biology, and a growing sense that materialism had serious gaps.

Dr. Egnor shares how philosophical honesty, scientific curiosity, and a surprising moment of divine encounter opened him to a new possibility that God not only exists, but that the Christian story offers the best explanation for the human mind, moral law, and the universe itself.

Guest Bio:

Michael R. Egnor, MD, is a Professor of Neurosurgery and Pediatrics at State University of New York, Stony Brook, has served as the Director of Pediatric Neurosurgery.  He received his medical education at Columbia University College of Physicians and Surgeons and is an award-winning brain surgeon. His new book, The Immortal Mind: A Neurosurgeon’s Case for the Existence of the Soul, explores the scientific and philosophical evidence for the soul, arguing that the human mind possesses faculties such as consciousness, free will, rational thought, and self-awareness that cannot be reduced to physical brain activity alone.

Episode Transcript

Molly Worthen is an academic, a historian of religion, a Yale-educated professor at UNC-Chapel Hill, and was an agnostic for decades. She studied Christianity, wrote about it, and even lived alongside devout believers. But belief itself? That always felt just out of reach. In this conversation, Molly shares how God gently disrupted her intellectual framework, used unexpected relationships (including Pastor J.D. Greear), and led her on a rigorous investigation of the resurrection that changed everything.

Listen as she unpacks:

If you’re a skeptic, seeker, or a believer walking with one, this is an invitation to deeper reflection.

Can reason, morality, and public good stand without God?

Allison Leonhardt once thought so. An atheist from her teens, she was convinced religion was outdated, the Bible unreliable, and morality explainable through modern thought and politics. With The God Delusion in hand, she challenged religious teachers and built her worldview around science, social justice, and self-made meaning.

But when the pandemic forced her into isolation in a foreign country, and a friend casually invited her to watch an online church service, something unexpected happened. Curiosity gave way to conviction, not through pressure or platitudes, but through Scripture that spoke directly to her experience.

Her career has taken her around the world as she spent several years working in finance and management in the United Kingdom.

What would lead a Jewish man, raised in an Orthodox home, who didn’t even know who Jesus was, to become a Christian pastor, podcast host, and author of a book on the evidence for Christ?

David Shapiro shares his unlikely journey from strict tradition to sincere faith. Growing up in Queens, New York, David was immersed in Jewish customs, Hebrew school, and temple life. But over time, he began to question the rituals and drift from belief altogether. What followed was a long road through agnosticism, atheism, military service, and a successful career in martial arts, all while pushing God further and further away.

Yet, in the quiet moments, and even in unexpected places, God kept nudging.

Guest Bio:

David Shapiro is a pastor, chaplain for a local fire department, co-host of the Boundless Bible podcast, and a soon-to-be published author of Jesus Christ: A Lot of Evidence. Raised in an Orthodox Jewish home in Queens, NY, David never imagined he’d one day come to faith in Jesus—let alone teach others about Him. With a doctorate in religious education, a background in professional martial arts, and a testimony that spans atheism, agnosticism, and deep academic study, David now uses his unique story and voice to help others encounter the truth and grace of Jesus Christ.
