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.

What if the reason you struggle to believe is because life has taught you not to trust?
For years, Nate Hanson was deeply committed to Christianity. Influenced by voices like Francis Chan and immersed in ministry, he devoted his life to radical discipleship and church planting. But after years of burnout, disappointment, and difficult questions, cracks began to appear in the faith he had always known. What followed was nearly a decade of public deconstruction through his podcast Almost Heretical, where he wrestled honestly with doubt, theology, and whether Christianity could withstand serious scrutiny.
