^^^Brain the book of Revelations and prophecy in general are very hard to digest and understand and take for fact IMO.. You will find many pastors share different views..
I don't even dare to try to understand it and or reason it out any more.. I prefer to enjoy the present and live life in the moment as I am not concerned about the end of times.. I know where I am going when I die as you do to. I know to look out for false prophets and or when forced to put markings on my body that is forced by society (if that even happens in my life time)..
So I say take caution when trying to understand Prophecy and or the book of revelations because in can easily branch off and get twisted into some kind of cult if not lead purely by the holy spirit....
My take anyways on predicting future events in the bible or by prophecy....
