I just bought this devotional for my whole family (6 copies for Christmas).
The reason why I have enjoyed this devotional so much is because it actually has the Bible as it's main section. Many devotionals use one or two verses and then come up with their own thoughts/interpretations/beliefs. This devotional is probably 55%-60% straight Bible and then Phillip Patterson adds some solid food for thought. My one worry was that it would just have the stories and would miss out on the theology found in the prophets, and letters of Paul. But so far (note I'm only on day 22 so far) he has quoted probably 40 or so passages that connect with the story we read.
The one note I would say is he's goes right through the Bible. So many of the stories fall in Genesis and Exodus. Although Patterson does give insight to many different parts of the Bible during these sections, you may choose to jump around and do some of the 150 New Testament stories to shake it up. Either way, I fully recommend.
May God bless you as you read and learn more and more about our Lord and Savior Jesus Christ.
