Each of the four views that are the focus of the book draw your attention to individual words and phrases in Revelation in different ways, which gives you plenty to think about. However, the covereage of the "New heaven and Earth" is totally one-sided: the author almost exclusively presents the "non-literal" side as if the "literal" side speaks for itself; if you take it literally, certainly there's plenty that can be said to confirm that view and challenge the "non-literal" view.
An excellent book that takes a realistic and balanced view of each position. As a former Bible College lecturer with an MA in Biblical Studies I would recommend this book to anyone wanting to understand the positions on the book of Revelation.
Before you read a commentator's own interpretation of Revelation, read this book!As Steve Gregg points out in the intro, there are no other commentaries like this one. This book is not meant to provide specific and detailed facts about every single phrase in Revelation, but it does exactly what the author intended: compare the style and general foundations of each school of interpretation. The main idea of each interpretation is captured in the author's comments on every section of each chapter. This is the perfect intro to Revelation because it is unbiased and all 4 views are presented equally. Once you read this book you can then decide which interpretation you would like to pursue for further in-depth study by choosing a commentary devoted to that specific interpretation.
