I guess this is where we need to identify “Babylon the great”....for in doing so we can answer those questions.
So who is this harlot who “rides” the beast and who "has a kingdom over the kings of the earth" and has dominated over them?
What is the connection between her and original Babylon, of whom she is a type?
Going back in history we see how the original city of Babylon came into existence.....Noah’s great grandson Nimrod, set himself up as the first political leader and creator of false worship. He was an opposer of God and with those who followed his leadership, were going to set themselves up in opposition to God....to make a great name for themselves. The command they received was to spread abroad in the earth, but Nimrod and his cronies had other ideas...
The tower they were building was to have its "top in the heaven....legend has it that it was supposed to save them if there was another flood?
Genesis 11:1-9....
“The whole earth had a common language and a common vocabulary. When the people moved eastward, they found a plain in Shinar and settled there. Then they said to one another, “Come, let’s make bricks and bake them thoroughly.” (They had brick instead of stone and tar instead of mortar.) Then they said, “Come, let’s build ourselves a city and a tower with its top in the heavens so that we may make a name for ourselves. Otherwise we will be scattered across the face of the entire earth.” But the Lord came down to see the city and the tower that the people had started building. And the Lord said, “If as one people all sharing a common language they have begun to do this, then nothing they plan to do will be beyond them. Come, let’s go down and confuse their language so they won’t be able to understand each other.” So the Lord scattered them from there across the face of the entire earth, and they stopped building the city. That is why its name was called Babel —because there the Lord confused the language of the entire world, and from there the Lord scattered them across the face of the entire earth.” (NET)
So Babylon was the place from which all false ideas about God and about how humans should worship, originated. It is the springboard from which false worship and false religious ideas spread throughout the whole world.
Some scholars recognize Nimrod as the first human to be deified, apparently 'placed among the gods' by his mother after his violent death. She then claimed the title “mother of god”.....a title that was later transferred to Mary in Roman Catholicism. Mother goddess worship was ancient even when Jesus walked the earth.
This is the Egyptian goddess Isis and child Horus.
Isis, Osiris and Horus were also presented as a trinity of gods...but the concept goes back to Babylon.
Nimrod is also closely linked with Tammuz whom the unfaithful Israelite women were seen weeping over. (Ezekiel 8:14) He was the god who died in the Winter but came back to life in the Spring....hence the weeping for him.
So when we see familiar images and teachings in false worship as we do in the beliefs they all hold in common, such as multiplicities of gods, an immortal soul that departs from the body at death to go to either a heaven of bliss or a hell of eternal torment.....specially robed religious leaders with high sounding titles, don’t we have to wonder why we see these very same things taught in Christendom? They were entirely absent from anything taught by Jesus Christ, but skillfully overlaid and woven into scripture to appear as if they were.
The "war in heaven" is in Revelation 12 and John was transported to the "Lord's Day"....to a future time...the time we are living in right now. The war in heaven did not take place before sin even entered the world of mankind. Sin began with the first rebel, not in heaven but here on earth in the garden.The other angels were recruited after satan's original rebellion. God allowed his to test out all of his children.
If the humans had exercised their free will differently, they could have prevented sin from entering the human race....all they had to do was obey one simple command and satan would have been dealt with in the heavenly realm without it causing any trouble for the humans.
