The author did a very nice job of creating a "guide" to help people through the sometimes challenging task of writing an effective sermon while still remaining faithful to the text of the Scriptures. He takes you through the process step by step, starting out with inductively coming at the Scriptures and then onto development and design of the actual sermon. I sincerely appreciate the Inductive approach that the author takes in the book as it closely reflects many of the steps that we did in the Inductive Bible Study Classes we did at our church. This book is a highly recommended resource for anyone that wants to dive into expository preaching, but is a little unsure or comfortable with the "how" part of the process. This book is a little more on the advanced side, so if you are merely curious about expository preaching, you might not get into this book as much as someone interested in the mechanics of how to create an expository sermon. With that said, the author has some great examples, excellent supporting charts, and explains each step very well. This will be a book that you reference and tweak the steps to make them your own for whatever works with your style. I received a copy of this book from B&H Academic for me to do a review on it. In full disclosure, I was not required or requested by B&H Academic to write a positive review.
I have read countless books in the field of homiletics, but none has matched this one. Dr. McDill has given us arguably the best homiletics book since Broadus' first edition of The Preparation and Delivery of Sermons, and 12 Essential Skills looks to be the standard for preachers for the next one hundred years.
