My passion is the Kingdom of God. I hold a PhD from the University of Wales, Trinity Saint David. I wrote my thesis "The Lord's Supper as an Anti-Imperial Praxis" under Drs. William S. Campbell and Kathy Ehrensperger. I serve as the Senior Research Professor of Biblical Theology at Criswell College (Dallas, TX). For ten years I served as the Editor of the Criswell Theological Review (CTR).
I also taught for 18 years the Presidents' Class at First Baptist Church, Dallas, Texas, a Sunday morning Bible study I taught verse-by-verse through the Scriptures.
