This book is well written, the terms are fully explained and in order. If you reflect on the "personal application questions" at the end of each chapter, you will discover a time of spiritual growth and deeper fellowship with God; as you apply the teachings of scripture to your own life! I realize you can acquire the same information in a second hand textbook version, but breaking the information up in seven parts removes the pressure or the sense of urgency to rush ahead.
I find that reading this book is easy, although some content could be deemed as repetitive, it does get the message across. I have not finished reading this book but what I have read has been enlightening.
