No use in being subtle here. These are the books I want you to buy for me.
- Preaching and Preachers, D. Martyn Lloyd-Jones
- The Supremacy of God in Preaching, John Piper
- Between Two Worlds: The Challenge of Preaching Today, John R. W. Stott
- Christ-Centered Preaching: Redeeming the Expository Sermon, Bryan Chapell
I guess buying only one would be fine too.
