The document summarizes key events from Revelation 15-16, including the seven last plagues and the battle of Armageddon. It describes how the sixth plague involves the drying up of the Euphrates river, Satan sending out three evil spirits to deceive people, and the gathering of armies for the battle of Armageddon. The seventh and final plague then occurs, marking the end of Jesus' mediation and the pouring out of God's wrath. Satan makes one last attempt to destroy the faithful with this final battle, but will be defeated with Christ's return.
