"David: 90 Days with a Heart Like His" by Beth Moore is a devotional book that goes into a large amount of detail to tell the story of David, from shepherd boy to king, "warts and all." Beth Moore's thought questions in the daily lessons are probing and thought-provoking, and the lessons and questions certainly can be used by the Holy Spirit to teach and convict us. My wife and I had recently finished Moore's 90-day devotional about Paul, and now we are about 1/4th the way through this book on David. We enjoy it because the lessons have us read main lesson scripture, and scripture that is background for or ancillary to the main lesson, and that provides application to the lesson. It also has space for daily prayer requests. I'd certainly recommend this book to others. And men, it's all right to read a devotion by a woman...but is best if your wife will read and study with you!
My Ladies' Bible study group just began using this book. We are only up to day 15, but have been very impressed with the content so far. I have really enjoyed that each day is a relatively short study, but packed full of insight and very thought provoking questions. I also like the time of reflection and devotion at the end of each day.
