A fresh, contemporary perspective on the book of Daniel provides helpful commentary on its prophetic passages. Study questions at the end of each chapter make it a helpful book for group Bible study.
Campbell did his research, I'll grant him that. Unfortunately, he added too much of his American-cultural Christianity to this study. Page 10 speaks of God's judgment on those disobedient Israelites, and I can see how this message of the angry deity who punishes and destroys comes as an assault to the same people who hear Christians swooning about God's love for them, the Saved.
It's just a slight shift to resolve that disparity: God created a balanced natural order that includes natural consequences. When managed according to His plan, life is reasonably well ordered. In contrast, continued rebellion against these principles--whether you believe in the All-Mighty or not, the apple still falls from the tree--will result in disorder--the 'punishment' for disobedience.
The seepage of religiosity in this book poisoned the entire work for me. There are far better commentaries than this, even the notes in a good Study Bible will invite the reader to a deeper understanding of how to live as a God-follower in adverse cultures.
