Why does heaven and the earth both rejoice over Babylons destruction?
The Christians who were persecuted/martyred by Antichrist in the first half of the Tribulation and are now in Heaven after the Main Harvest Rapture will rejoice because God will completely destroy Babylon, avenging their persecution and martyrdom. The people of the earth who accept Jesus as Savior and the Jew/Israeli who will be completely redeemed by Jesus will rejoice because Babylon has now been destroyed. Both Christians, Jews/Israelites and Gentile Believers in Jesus will all rejoice, because their persecution by Antichrist/Babylon is now over.
