Babylon

Things to Understand:

    1. Those who worship the beast will get plagues (Revelation 16:19)
    2. Harlot - Apostate church (Revelation 17:1-5)
    3. In union with Governments (Revelation 17:1-5)
    4. Mother of Harlots (Revelation 17:1-5)
    5. God's people called out of her (Revelation 18:1-4)

Revelation 16:1-2

Then I heard a loud voice from the temple, saying to the seven angels, “Go and pour out on the earth the seven bowls of the wrath of God.” 2 So the first angel went and poured out his bowl on the earth; and it became a loathsome and malignant sore on the people who had the mark of the beast and who worshiped his image.

The plagues fall on the people who worship the mark of the beast and not God's people.

Revelation 16:19

19 The great city was split into three parts, and the cities of the nations fell. Babylon the great was remembered before God, to give her the cup of the wine of His fierce wrath.

The plagues fall on the city of Babylon. The city represents a spiritual city and not an actual city.

Revelation 17:1-5

Then one of the seven angels who had the seven bowls came and spoke with me, saying, “Come here, I will show you the judgment of the great harlot who sits on many waters, 2 with whom the kings of the earth committed acts of immorality, and those who dwell on the earth were made drunk with the wine of her immorality.” 3 And he carried me away in the Spirit into a wilderness; and I saw a woman sitting on a scarlet beast, full of blasphemous names, having seven heads and ten horns. 4 The woman was clothed in purple and scarlet, and adorned with gold and precious stones and pearls, having in her hand a gold cup full of abominations and of the unclean things of her immorality, 5 and on her forehead a name was written, a mystery, “BABYLON THE GREAT, THE MOTHER OF HARLOTS AND OF THE ABOMINATIONS OF THE EARTH.”

The judgement would fall on the great harlot (unfaithful woman; the unfaithful woman represents an apostate church) that sits on the water (people). She commits fornication with the kings of the earth. The apostate church makes a union with kings (governments) instead basing its trust in Christ. A woman (a church) sitting on a scarlet beast (a power). Being the mother of harlots means that the daughters that are harlots are churches that also aren't following the bible but following to a degree the teachings of the mother church.

Revelation 18:1-4

After these things I saw another angel coming down from heaven, having great authority, and the earth was illumined with his glory. 2 And he cried out with a mighty voice, saying, “Fallen, fallen is Babylon the great! She has become a dwelling place of demons and a prison of every unclean spirit, and a prison of every unclean and hateful bird. 3 For all the nations have drunk of the wine of the passion of her immorality, and the kings of the earth have committed acts of immorality with her, and the merchants of the earth have become rich by the wealth of her sensuality.” 4 I heard another voice from heaven, saying, “Come out of her, my people, so that you will not participate in her sins and receive of her plagues;

God's people will be called out of babylon. That means God will call all his people out of all apostate churches to follow him. The plagues will not fall on those people that come out.
