Mohler argues that preaching the Word of God is essential to worship. And, "...the only form of authentic Christian preaching is expository preaching."
The church has a crisis today because we no longer believe that hearing and responding to the Word of God is of crucial importance.
This is a book every pastor should read. If a pastor truly believes he is dealing with the very Word of God, why would he want to preach anything but that Word? That means preaching the full Word not just picking a passage here and there!
