Ever hear of the "New World Order" folks? Or "one world government"?
What about the Revelation 13:1 beast kingdom that comes up out of the "sea", that is to have ten horns, seven heads, and ten crowns? You've heard of that for the end of this world, right?
Even though the false doctrine of Amillennialism began in the 2nd century A.D. when pagan Gnosticism began creeping into the Christian Church, that doesn't mean it is a Biblical doctrine just because of being that old. The pagan Gnostics still exist to this day, and they have not changed their plan for world takeover in prep for the one they... worship, Lucifer.
These people who follow today's Gnosticism are associated with the Occult secret societies. One can basically put all the pagan secret societies into one boat; they all worship Lucifer, even secret fraternities that have strong Christian memberships at their lower levels of what they call the Lesser Mysteries. The high level members know who they worship, the devil, and they are preparing the whole world for his coming to take reign over all this earth at the end.
That is why even the deceived on their doctrines of Amillennialism are so fervent in supporting it even when it goes directly against the written Bible Scriptures. It has been around so long that the deceived have gotten attached to it like a thick vine grown from a Jack and the Beanstalk type bean.
This is why Amillennialism tries to convince the gullible that the Revelation 20 "thousand years" about Christ's future reign isn't literal, but symbolic only; even though that "thousand years" reign by Christ and His elect for the future AFTER His return is well defined in plenty of Bible Scriptures, including in the Old Testament prophets.
Those Gnostics behind the theory of Amillennialism want to destroy that "thousand years" reign by Christ Jesus. And don't be fooled brethren in Christ by those deceived brethren on that Amill doctrine that claim it is Biblical just because it goes back to the 2nd century A.D. That 'something is true because it is the oldest' ploy has been attempted with pushing newer Bible translations from older claimed Bible manuscripts too, when there is little actual proof. New and Improved doesn't work with God's Truth in His Word.
Think about the building of the first city by Cain in the "land of Nod" where Cain took his wife. The only most ancient creation account other than given Moses in the Book of Genesis is found in the Babylonian cuneiform clay tablets. And those tablets report of a history going back further with the ancient Sumerians in that area before it became known as Babylon.
I believe that is where Cain went to, and was the actual "land of Nod" mentioned in Genesis 4 where Cain built the very first city. Per the ancient Sumer history written in the tablets, that would fit the one they called Sargon I. Sargon was of Semitic origin per their history, and he began the very first IDOL worship of earth history. That is where ancient Baal worship began, in ancient Sumer. Why do I mention this?
It is because during the time of king David and his Solomon, with the building of the city of David, and Solomon's temple, pagan workers in stone and metals were gotten from king Hiram of Tyre, a pagan Phoenician that was friends with king David. The children of Israel did not have the expertise in stone and metal working, so David and Hiram traded workers. Other than the pagan Canaanites which Israel was not able to destroy per God's command, these workers from Tyre were pagans that also crept in among the children of Israel. And many of them became religious Jews that have been planted among the Jews for so long, that it is impossible to distinguish who they are today, and thus Christ's parable to the tares in Matthew 13.
One of the ideas that came out of ancient pagan Babylon was the so-called 'Mysteries', also known as 'mystery schools'. In ancient Babylon the priesthood there controlled entry in among them through initiation by certain rituals, and then a probationary period. Then the Mysteries would be revealed to them. What those Mysteries were and are about involve the Occult, things God told us to not mess with per His laws. Yet today's secret societies are still practicing all those ancient Mysteries from the devil.
Because the theory of Amillennialism converts certain Biblical texts meant literally instead as being symbolic, that is a concerted and vain attempt to change what God's Word actually teaches. That kind of movement of interpreting The Bible mostly as allegory was one of the problems the Christian school at Alexandria, Egypt had. Origen and Clement both got in trouble for it.
Amill says Christ's "thousand years" reign of Revelation 20 is only SYMBOLIC, and not LITERAL. Thus they also deny Old Testament Scripture like Zechariah 14 which is about Christ's future 2nd coming back to Jerusalem and His future reign with His elect over all nations, including the unsaved nations. They also deny references to Christ's future reign over the wicked as described by Apostle Paul. Amill instead wrongly believes that at Christ's future return, all the wicked are then immediately destroyed, and right then we go into God's new heavens and a new earth time. They simply skip any Bible reference of the wicked still existing after Christ's future return.
And then, Amill makes TODAY, our PRESENT DAY, special, in the sense that Lord Jesus is REIGNING NOW! and that His Kingdom has come today! And that even though all the wickedness is still going on in this world. It's a theory of a madman! But hey, it serves the Occultists well, because Lucifer has always wanted to be God, and worshiped in place of God. That was his original sin by the way, coveting God's Throne for himself, wanting to be God. No matter that Lucifer and his followers can setup a fake world kingdom with wickedness still going on in it.
