Reasoning Requires Faith - Jeffrey Geibel's 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.
