There is a book that explains the topic of demonology very well by, Dr. Dennis G Lindsay D.Min called "Giants, Fallen Angels and the return of the Nephilim" I highly recommend reading this book, I can't do any justice in my blog based on the deep research that Dr. Lindsay says on this topic.
Dennis G Lindsay D.Min wabiza ngokuthi "AmaGiants, Angilosi Awile kanye nokubuya kwamaNefili" Ngincoma kakhulu ukufunda le ncwadi, angikwazi ukwenza ubulungisa blog yami ngokusekelwe ocwaningweni olujulile uDkt.
