Babylon in the largest sense is the whole world. In the beginning "the waters were gathered together in one place"; the earth was one also (Gen 1:9,10). Man and his language was one upon the earth (Gen 11:1). God saw that their unity was causing them to be a god unto themselves (Gen 11:4-6). This was the first Babel (V-9). God humbled them by confounding their language and spreading them out on the earth which was then one land mass (Gen 11:7,8). In Ps 104:8, God caused the mountains to rise and the valleys to sink. Before this time the flood only had to cover short mountains (verse 6) separating into continents and islands the land mass and even further separating mankind (Gen 10:5,25). All nations are thus from Babel and have the sins of Babel in their blood. Now a spiritual Babel is being built, a United Nations of the world. The results will be the same (Rev 16:18,19). Babylon was and is both secular and religious. There are larger and smaller types of each. For instance, the larger type of secular Babylon is the whole world; and a smaller type is the U.S. Let me prove this to you by looking for a moment at religious Babylon. In Rev 17:5 she is called "Mystery Babylon the Great, the Mother of the Harlots and of the Abominations of the Earth". We are told by many Protestant churches that the Mother is the Catholic Church because the other churches came out of her. This is very uncomplimentary of the Protestant churches because in this title the daughters are being called the "harlots". The mother is the great harlot in Verse 1. The Catholic Church is only a smaller type of a much larger type. This mother is much larger and older than the Catholic Church. Let me prove this. In Rev 18:24, she is guilty of the blood of the prophets and of the saints (To be guilty of blood, you must either physically kill or spiritually kill because you do not warn them of sin (Eze 3:18,19) and of all that have been slain upon the earth. You can not blame the Catholic Church for the death of the prophets; that was Israel's apostasy, and it was before Catholicism existed. The all mentioned here is beyond their scope too. Jesus said that Israel was guilty of "all the righteous blood shed on the earth, from the blood of Abel the righteous unto the blood of Zechariah" (Mt 23:35). According to that verse, members of the mother harlot existed from Israel all the way back to Cain. The mother is the corporate body of apostate religion, and the daughters are the members of that body; just as the church is a corporate body, and the individual churches are members of it. The harlot rode the beast with the seven heads identified in Rev 13:1,2 and Dan 7:4-7 by the beasts which were symbols of world ruling kingdoms (Example: The Lion with eagles wings was symbol of Babylon, the leopard of Greece, and the bear of Medo-Persia). In Rev 17:9-11 :the seven heads are seven mountains [not hills of Rome but seven kingdoms] on which the woman sitteth: and they are seven kings; the five are fallen [Egypt, Assyria, Babylon, Medo-Persia, and Greece], the one is [Rome, the head that was smitten unto death but revived in Rev.13:3], the other is not yet come [corporate worldwide Revived Roman Empire the Dragon of Rev12]; when he cometh, he must continue a little while [3 1/2 years]. And the beast that was and is not is himself also an eighth [beast of Rev 13] and is of the seven". The eighth kingdom is made up of all of the seven world empires because the woman sitteth (present tense) on all seven. These kingdoms have lost their individual dominion, but their lives were prolonged (Dan 7:12), and they are still with us exercising dominion corporately in the end time beast. The coming of Christ will destroy all these kingdoms together (Dan 2:35,44).
Note: The aftermath of WWI brought the world together in fear of worse holocaust. They decided they needed a "man of peace" and the League of Nations was born. They gave no teeth to that beast and the aftermath of WWII brought renewed fear and unity which brought a revision to that beast, now called the U.N. The approaching war could be the one that brings forth the next revision in the beast, which will be called the Dragon. It will be Satan's body.
In Daniel's revelation, he deals with the beasts from his time and forward and not with Egypt and Assyria which were before him. Daniel 7:23 says, "The fourth beast [counting Egypt and Assyria, this is the sixth beast] shall be a fourth [sixth] kingdom upon earth [meaning all four (six) are still on earth] which shall be different from all the kingdoms [corporate in nature, because it is the first to become a Unites States of the world] and shall devour the whole earth". Inside the fourth beast are all the other beasts which are also the whole earth. The whole earth is made up of the seed of these kingdoms. There is only one Corporate kingdom that has the seven heads and the ten horns (all nations), and it is not the E.C.; but the U.N. The E.C. is only a smaller type of the larger type of the U.N. The end time beast of Rev 13 will have within it every tribe, people, tongue, and nation whose name is not written in the Lamb's book of life (Rev 13:7). The sixth verse of the sixth chapter of the sixth book of the New Testament identifies the beast, the corporate old man (Rom 6:6). The Mother harlot has exercised religious authority over the beasts throughout history. The Catholic church is only a smaller type of a larger, Babylonish religious system as the U.S. is a smaller type of secular worldwide Babylon. As a small type it will incur the same judgment as the larger type as an example to the world. Many say that they do not see the U.S. in scriptures. Does it sound reasonable that what is arguably the greatest nation on earth would not be mentioned in scriptures? I do not think so. The U.S. is now at the pinnacle of influence over the world through the U.N., NATO, foreign aid, military strength, trade, and many other avenues. Every other world-ruling power is mentioned along with their destruction, so the U.S. is not left out. In Tremble Ye Women I explained how the Lord identified the U.S. as Babylon to me. Many proven prophets and teachers have identified the U.S. as Babylon. After being told by the angel of the Lord that America would be destroyed, Dumitru Duduman asked for biblical proof to show the Americans. The angel said, "Tell them to read Jeremiah 51:8-15... also Rev 18", clearly identifying America as Babylon.
