Free audio of the 2009 Expository Preaching Workshop sponsored by Southwestern Baptist Theological Seminary is available here. Here are the titles of the sessions.
David Platt – For the Glory of God: Theological Foundations for Text-Driven Preaching
Calvin Pearson – The Day that Preaching Died
Steven Smith – Expository Preaching and the Nature of the Church
George Harris – Tips for Effective Sermon Preparation
Jerry Vines – Text-Driven Preaching - Preaching Jonah
David Platt – For the Sake of the Nations
Jerry Vines – Jonah
David Allen – Preaching the Difficult Passages of Scripture - Heb 6:1-6
Paige Patterson – The Gospel in Prepositional Phrases
In particular, I would commend David Allen's talk on Hebrews 6. His view of this warning passage is also my view.
