Content is better than the title!
Format: Paperback
The best quality of Heiser as a scholar/writer in my opinion is that he appreciates the academy but does not acquiesce to its influence. This is seen most in his correct interpretation of the identity of the sons of God in Gen 6 and the identity of Satan in Is 14 and Ez 28 etc. which were long abandoned and scorned by the academy.
All 60 articles are well written with clarity and brevity!

Read all of his books, you won't be dissapointed.
Format: Paperback
I love Dr. Heiser books, but I wanted to step back from the spiritual realm and reconnect with scripture again. This book is light, easy to read, and like all his content, so eye opening. I am alway slapping myself in the forehead and wondering how I didn't know or notice things. "I Dare You Not to Bore Me With the Bible" is another of his books that I'm reading simultaneously. If you want to go deeper in Bible Study, this is the book. It's helped me forgive a lot of the Bible "hangups" I have that were very cultural or significant for reasons I missed. Get those 2 books (this and the one I mention above), and then when you're ready to really have your understanding of G-d and the Bible blown out of the water, move on to Unseen Realm, Reversing Hermon, Supernatural, and all of the others. If you desire to understand the Bible, and not just show up on Sunday, read everything by Dr. Michael Heiser, his website is a great resource too. So grateful for the work he does.
