The exegesis is a little TOO detailed. Maybe if the writers gave a briefer summary before going into so much detail. On the other hand, it is very thorough.
It is organized in New Testament order - so if you are studying the Old Testament there is not a straightforward method for keying your study to NT quotes or alusions. There is an index keying OT passages to page numbers in the commentary; but that's real cumbersome.
I am thinking that this book may be more useful in a bible software (such as OliveTree) that alerts users to resources that discuss the passage being studied. So, if I am studying some passage in the OT that is quoted in the NT I would get an alert that this OT passage is discussed in the Beale/Carson commentary.
Unfortunately, I already own the real-world version of the book and don't want to spend more money on a bible-software version.
This commentary is the "go-to" commentary to understand the New Testament. The quotes are explained as well as the allusions. One can see that the New Testament is grounded in the Old Testament. The old covenant is changed with Jesus but remains the ground level of the new covenant. I cannot even begin to express how useful this commentary is for Bible study. I would recommend that every Bible student get this book.
This book is long (1152 pages). It can be read from beginning to end; but I suspect that most readers will not use the book in that way. It is reference book. Its best use is to trace the use of the Old Testament (OT) in a particular New Testament (NT) book. In other words, how did a particular NT writer make use of the OT in his NT book? The answer to this question is a continual fascination, especially for modern Bible readers who have forgotten that for first-century Christians, "the Scriptures" were the books of the OT. For example, look at how this book documents the use of the OT in the NT book of Revelation. This chapter alone makes this book worthy of purchase. This book opens a door into the mind of the first-century Christians, and how they interpreted the OT. For many Christians, this will be an eye-opening experience. The book is well documented with an extensive bibliography. Not many books have even attempted what this book has accomplished well. I recommend the book highly. Clear your calendar, and get ready for some serious Bible study.
