What does it mean for the gospel to be functionally central — not just theologically true in the abstract, but actually animating the way a pastor preaches, thinks, and lives? Mike Bullmore, author of The Heart of Preaching: The Functional Centrality of the Gospel in the Life and Work of the Preacher, joins Brian From to answer that question. A veteran pastor who planted Crossway Community Church 28 years ago and now preaches at Park Community Church in Chicago's Lincoln Park neighborhood, Mike makes a simple but convicting diagnosis: the moment a preacher reserves gospel proclamation only for evangelistic sermons and then shifts to discipleship content for believers, he's already gone off course. The gospel isn't just the entry point — it's the flywheel that keeps everything else moving. He also speaks directly to the pastor who has quietly grown apathetic, lost the awe, and is grinding through sermons on fumes — with a word from Psalm 103 about God's compassion and a surprisingly practical prescription involving the Gospel of Mark and the book of Leviticus.
