The 3 ancient primary "gods" (major demonic forces) which held sway in the ancient world and worshipped by the pagans in all cultures are well catalogued in the Bible and other ancient writings. They were essentially slowly cast out for 2000 years after Jesus and especially in the Western World - and Jesus predicted their return. They are back in full force (starting about 60 years ago) and the book describes who they are and how and why. It's age-old spiritual warfare taking place here on Earth today in spades. It is evident everywhere once it is explained as well as Jonathan Cahn does it.
Even if you are not specifically a "Christian" it will be obvious to you.
Thank you very much.
