When I first looked this book over, I was a bit disappointed because it seemed extremely simple. It seemed there wasn't much to it, and I'm one of those folks who likes to go deep. However, as I started going through it, following its regimen for daily study, the method revealed more and more depth in Philippians and Colossians than I'd ever suspected.
This is a book whose primary purpose is to get you into the Bible, and to help you see what treasures it contains. It doesn't tell you, but instead shows you the path to see for yourself. It did a wonderful job of putting the Bible into your heart and kept the focus on scripture.
