A light reading of Chafer's biography will tell you that he was one of the co-founders of Dallas Theological Seminary and an important figure in the popularity of Dispensationalism in the modern church. Because of that, this book focuses heavily on Satan's role in the dispensations of scripture. Even more, Chafer's main focus in this book is on Satan's role eschatologically more than anything else. While it is important to consider Satan's role and eventual defeat at the end of time, I was more hoping to come to this book and learn about Satan and spiritual warfare in other parts of Biblical history as well as his methods in our present day. Chafer really doesn't tackle much of this and the majority of this book is focused on his role in the last days. That being said, the last third of the book is definitely worth the read as Chafer does a great job expounding on how Satan tries to mimic Christ to deceive believers. In addition to that, Chafer's last few chapters on the believer's position in Christ and victory over Satan, the flesh, and the world through the Cross is also very good and encouraging for the believer. So, overall, this was an average book with some good spiritual truths here and there (especially towards the end of the book) but it had too heavy of a focus on Satan in the end times to make it a well balanced book on who Satan is and what he does.
