You do not know it is never been a problem with comprehension. You are making a declaration based on what you want to believe.This is about the stupidest argument one can make about the KJV.
For hundreds of years (and even as we speak) Christians had no problem understanding what was written in the Authorized Version (KJB). This is another straw man erected by lovers of corrupted bibles such as the NIV. So you have actually been snared by the devil in this regard, and you don't even know it.
As to Mystery Babylon, it has run side by side with the Mystery of Iniquity since early times. Babylon was the first center of idolatry and false religions, and it will culminate under the Antichrist. Both Satan and the Antichrist, as well as his image, will be worshiped throughout the world. So Mystery Babylon will actually be centered in Jerusalem, which -- at that time -- will resemble Sodom and Egypt.
You still cannot deal with Eastern not being biblical in the KJV.
Or the false declaration God created evil.
If you like the KJV that is your choice. But your false argument that such as the NIV is from Satan's is,false, uneducated and cultic in nature, if not in fact.
I never said Satan and the AC would not have worshipers in the world. But it is a fact multitudes of martyrs will be in heaven for refusing to worship them.
And the 144,000 chosen of Israel plus some others were also refused to worship and be protected in Petra for 3 1/2 years.
As well as many Gentiles will enter the MK who never took his mark.
Nowhere can you show mystery Babylon will centered in Jerusalem. But it clearly is shown it will be in Rome.
Rome is destroyed to never rise again or have people. Christ will rule from Jerusalem until the end of time.
