It Is Finished is essentially a book that explains the New Covenant. I think many Christians don't truly understand the significance of the New Covenant and how it affects everything in our spiritual lives. This book does a fine job explaining the "how to" defeat sin in our lives. While this book is small it is jam packed with information. I also enjoyed the real life letters that were included as examples of people who struggle with the very topics he deals with in the chapters. If you desire to have a better understanding of the New Covenant this is a great read.
I received this book free from the publisher in exchange for my review.
