30 Days to Understanding the Bible
I think this book is a must read (must study) kind of book. Many people who've been through my course at church on understanding the Bible have commented, "I wish I had this course many years ago. It's helped me understand how the Bible fits together." People's eyes really light up when they study this book. It really puts the Scriptures together for them. A class (using this book) should be offered in every local church on an ongoing basis.
