6 Pay her back the way she also paid, and double it according to her works. In the cup in which she mixed, mix a double portion for her.
The phrase “Pay her back the way she also paid” refers to justice for the murder of believers and the deception of people in making them believe that they were worshiping the true Living God but in retrospect were worshiping a false god. God’s judgment will pursue those who participated in Satan’s work with double the punishment.
7 As much as she glorified herself and lived luxuriously, give her that much torment and grief, for she says in her heart, “I sit as a queen; I am not a widow, and I will never see grief.”
This false church lived off of the peoples’ donations and established with it multiple side businesses which supposedly was for God’s work but ended up in their pockets and exalted itself above all others, falsely asserting that judgment will never come to it. She is sadly mistaken. Judgment will come.
8 For this reason her plagues will come in one day—death and grief and famine. She will be burned up with fire, because the Lord God who judges her is mighty.
The phrase “For this reason her plagues will come in one day” means that once God is ready to bring judgment upon the false church. It will come quickly without warning.
The phrase “She will be burned up with fire” gives the idea that just as fire destroys everything completely, the Lord God will wipe it out from the face of the whole earth.
9 The kings of the earth who have committed sexual immorality and lived luxuriously with her will weep and mourn over her when they see the smoke of her burning.
Sexual immorality is in reference to spiritual decay. Anyone who is directed to leave Jesus Christ for a false Jesus will commit spiritual adultery.
The phrase “lived luxuriously” means that money played a big role in the motivation of deceiving the people.
Anyone who seeks a Jesus other than the Jesus of Holy Scripture without question will end up in the Lake of Fire for all eternity.
10 They will stand far off in fear of her torment, saying: Woe, woe, the great city, Babylon, the mighty city! For in a single hour your judgment has come.
The world will witness the destruction of this false religion.
Babylon is not to be taken as a real place but as a spiritual symbol. The reason for this is because of her description and the role she has played in history. Also, for one to commit sexual immorality, one has to be close to the truth or in the truth and who have abandoned the true God for a false one. That would narrow it down to a church that claims to be Christian but denies Jesus through their practices.
