In this episode of the J29 Coalition Podcast, Caleb Campbell sits down with pastor, scholar, jazz pianist, and author Mark Glanville to explore what it means to preach faithfully in a post-Christian, doubt-filled age. Drawing from his new book Preaching in a New Key, Mark unpacks how expository preaching must move beyond outdated models to engage both the head and heart of today’s listeners, who often come to church carrying skepticism, grief, and questions. Using jazz as a guiding metaphor, he describes preaching as improvisation within tradition—rooted in Scripture yet dynamically contextualized for the moment.
