Dr. Heiser's book, The Unseen Realm was groundbreaking and provides much new insight into the Scriptures. These videos dovetail with the book and give the student the opportunity to better understand Dr. Heiser's train of thought and how he arrived at the insightful conclusions in his book, The Unseen Realm. If you enjoyed the book, and you just can't get enough, then these courses are for you. Dr. Heiser's explanation of why we have evil in the world today was worth the work of taking the course for me. If your on the fence, I encourage you to take this course because you will emerge a better student of the Scriptures for having done it. God bless you in your studies!
