John Chrysostom
Archbishop
John Chrysostom, Archbishop, (350 – 407 AD) - Known as one of the greatest preachers of all time, John’s nickname, “Chrysostom” means “golden tongue”. His sermons are full of wisdom and illustrations still used by pastors today. He grew up in a Christian home and was dissuaded by his mother from becoming a hermit. He eventually became the Bishop of Constantinople (today’s Istanbul, Turkey). He often preached against the politicians of his day who he believed were doing harm to the church and society. Eventually this led to his banishment. He once stated, “Preaching makes me well. As soon as I open my mouth to speak, all my weariness is gone.”

Trevor Lohman
Neuroscience Researcher
Trevor Lohman is a clinical research neuroscientist, professor, and author whose academic path began in cellular and molecular biology before transitioning into gene expression and aging. Currently serving as an assistant professor at a medical school in Los Angeles, Trevor explores the intersection of neuroscience and cardiovascular disease. Despite a successful scientific career, Trevor experienced a seismic worldview shift. Once a staunch atheist deeply immersed in rationalism, he began to question the very foundation of his beliefs. His journey—driven by curiosity, intellectual honesty, and a deep love of science—led him not away from reason, but toward faith. His debut book, God’s Eye View, challenges the modern cultural divide between science and spirituality and reclaims the spiritual heritage at the roots of scientific inquiry.
