Paul Seungoh Chung has been concerned about how those living in non-Christian or post-Christian settings can encounter and be captivated by the Christian Gospel. He thought about this as he studied philosophy and then, theology. He has thought about it as he served as a pastor at local churches in Toronto, worked with a mission organization, Canada Mosaic Christian Alliance, as its speaker--and its chronicler, of sort--and taught courses on Christianity and science as a sessional lecturer at the University of Toronto. He's even been writing books to help him think, and the first of these, God at the Crossroads of Worldviews, has been published through the University of Notre Dame Press. And he probably will be thinking and learning about it for the rest of his life.
