Mark Dever is the pastor of Capital Hill Baptist Church in Washington D.C. and a prolific author. The video comes from Together for the Gospel. I can imagine many people struggling with jealousy when they see this video. Others, on the other hand, will be pleased to show this video to complaining wives saying, "See, by comparison I don't have many books at all!" Some of us will be encouraged by the "pile" he has on the floor! It's comforting to know we're not alone! (See also this picture of William F. Buckley's desk. How does he find anything?)
