How to Build an Expository Sermon Around One Big Idea

What if someone asks your congregation what Sunday’s sermon was about—and they couldn't say? Recorded during a rainy drive through County Cork, Mike Neglia and Nick Cady discuss a deceptively simple preaching discipline: find the main idea of the biblical passage, express it in one memorable sentence, and let the sermon move through that sentence.

Nick explains why he began doing this, how he studies the text before crafting a thesis, and why “one big idea” must never replace careful verse-by-verse exposition. He and Mike test the approach against real sermons from Joshua 2, 2 Corinthians 5 and Revelation 20. Along the way, they consider sermon titles as promises to listeners, introductions that build anticipation, outlines people can actually remember, and whether any of this requires slides.

This is a practical conversation for pastors and Bible teachers who want their sermons to be faithful to the text, clear to the congregation and memorable beyond Sunday morning.
