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.
