This is an excellent collection of essays by the greatest preachers in the Reformed tradition today. Some of the topics include The Primacy of Preaching (Mohler), The Teaching Pastor (Sproul), Evangelistic Preaching (Alexander), and The Foolishness of Preaching (Boice). John Piper's essay on Preaching to Suffering People is one of the best things he has ever written and by itself is worth the price of the book ten times over. Derek Thomas' essay on Expository Preaching is full of very good instruction. Joel Beakes' contribution on Experimental Preaching is also excellent. I highly recommend this book for pastors. If you are not a pastor, consider purchasing it for your pastor as a gift. He will be appreciative.

The Fact that this book is excellent should be no surprise, merely take a glance at the authors. This book will probably offend pastors who are in to the modern pop pyschology, but then they probably wouldn't be reading it anyway. Granted, that was probably unfair but...
Naturally some chapters are better than others, here are a few:

"The Lasting Effect of Experimental Preaching"--the essay on spiritual formation--worth the price of the book.

"The Primacy of Preaching"--by Albert Mohler--very good, a wake up call to the church.

"Expository Preaching"--good and bad examples of expository preaching, very fun chapter.

"Preaching to Suffering People"--by John Piper. It is by Piper, enough said.

"A reminder to Shepherds"--By John Macarthur, a fitting close to a fine book.

Absolutely essential reading for upcomming (as well as seasoned) preachers. A true gem, very informative, and a must for all who proclaim God's Word.
