he was loosed for 1000 years, and that time is almost up
pretty much the book of revelation's main body is the first and second millennia, and it covers the prior age of babylon as well, which preceded the time of John
i recommend you read it again, and you'll notice that not once but TWICE the angel showing him the visions rebukes him for worshiping the angel, "i am the same as you"
there's a lot in there that you miss
read the Book of Enoch
you will then understand that angels are humans, with advanced knowledge and technology, it is completely lucid in Enoch, and that will cast you back to the times of Noah, which it extensively refers to, as well as the liberation of israel across the red sea, and that many of the "heroes" of the old testament were actually bad guys, like Daniel, for example, Solomon... complete trash, children of fallen angels
in Enoch you will learn that the Head of Days, who predicted the coming disaster that caused the Flood was regretful that they let one of the fallen one's offspring onto Noah's boat, and that this one had pale skin and red hair, like the angels btw
it's a lot to unpack but it's all there you just have to be alerted to a few key points and suddenly you will see it differently
for me, where before i couldn't quite believe in it, though i wanted to, now i understand it and the great news is that before the end of this decade the descendants of the angels are fulfilling their promise to return and "reap the harvest" and leave behind the fallen ones legacy to be burned in the second round of the same thing that caused the flood, and this time they won't fuck up
i know you probably won't believe anything i say but at least read revelation again after what i just explained
I will read it with the help of the holy spirit
