Dr. Hahn's new book, Understanding the Scriptures is truly an amazing work. Of it, he has said, "I believe this is my most important work." The book is not only full of amazing content--it's an overview of the entire Bible!--it is also beautifully illustrated and contains a number of tests and other educational aids. You can see some samples here. This book sells faster at conferences than any other book I think I've ever seen. Copies just fly off the table. If you don't have a copy, you need to get one.
