How to Build an Expository Sermon Around One Big Idea

Recently I had the opportunity to travel to Cork, Ireland on a ministry trip with a few other pastors. Our friend Mike Neglia has been pastoring a great church called Calvary Cork for the past 21 years, and he invited us to participate in a gathering to equip and encourage pastors and ministry leaders from Ireland, England, and Spain.

While I was there, I had the opportunity to record a podcast episode for the Expositors Collective Podcast about my approach to expository preaching.

Starting in 2020, I have gotten in the practice of distilling a “big idea” or thesis statement for the passage, and then using that sentence as my outline for the message.

For example, this coming Sunday’s sermon will be on Joshua 8:1-35. The title of the message is: “Moving Forward After Failure” and the summary statement is: “By God’s grace, our failures can become turning points toward renewed faithfulness and fellowship with Him.” I will use that sentence as my outline in this way:

  1. By God’s grace, our failures can become turning points… (Joshua 8:1-2)
    1. The failure at Ai (ch 7), God’s grace in times of our failure, and how our failures can be catalysts for good things if we respond rightly.
  2. …toward renewed faithfulness… (Joshua 8:3-29)
    1. The people of Israel did exactly what God called them to do, and it led to victory as they obeyed by faith
  3. …and fellowship with Him. (Joshua 8:30-35)
    1. The people of Israel renewed their covenant with the Lord and do what God called them to do back in Deuteronomy 27.

I developed this method of sermon preparation and presentation both out of frustration, and wanting people to remember my messages more – and by listening to others do it, and reading Biblical Preaching by Haddon Robinson and Preaching and Preachers by D. Martyn Lloyd Jones.

In this podcast episode, Mike and I talk about my sermon writing process, what it looks like step-by-step, and lessons I have learned along my journey of seeking to improve as a preacher.
