It Is Well: Expositions on Substitutionary Atonement is one of those texts that is simply a joy to read. Part of the reason is the topic. I love spending time pondering the stunning atonement of Jesus Christ. His work on the cross for us should leave us in a continual state of awe.
One reason I really enjoyed this book is that the authors (Mark Dever and Michale Lawrence) focus on fourteen different scripture passages that deal directly with the atonement. Each chapter in the book discusses one passage. This book is actually taken from fourteen different sermons that they preached on the atonement. In that way, It Is Well is a little different than most books because it reads like you are listening to sermons.
We cannot think too often on the substitutionary atonement of Jesus Christ. This book will help you in that. Enjoy.
