Why is the Book of Revelation difficult to understand?

The book of Revelation can be understood when God revels it to you. It has so much wisdom and knowledge way above our heads and understanding.That book is very deep on many things that man cannot understand without God help. You cannot understand it with human intelligences, or the carnal mind, or mans understanding, so don't try to figure it out, unless you let God show it unto you. The Bible is a sealed book to mans so called intelligence. The truth is hid no matter how much you want it. Get born again from above and the truth will be opened to you. Gods Word is Spirit, and is alive.
