The Armor of God: Standing Firm in Spiritual Warfare is another excellent Bible study by author Gregory Brown.
Based on Ephesians 6:10-20, the author takes all the elements Paul mentions in regards to the "armor of God" and explains in detail how each piece was used during Paul's day in regards to warfare. For example, when explaining the belt of truth he describes how the Roman soldier wore the belt and why it was crucial in a battle. These insights (some of which I'd never heard before) help make the study of Spiritual Warfare all the more interesting and easier to understand.
If you are a teacher, either for homeschool, or as a Bible study leader, this book will help you immensely. If you are a student of the Word, it will make your study time all the richer.
With reflection questions at the end of each chapter, the reader will acquire a solid foundation on why they have to stand firm in Spiritual Warfare and why they must put on the full armor of God each day. You will come out of this study equipped and ready to "stand firm."
