And I saw another angel fly in the middle of heaven, having the everlasting gospel to preach to them that dwell on the earth, and to every nation, and kindred, and tongue, and people, Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters. And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication. And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: And the smoke of their torment ascends up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whoever receives the mark of his name. Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus. (Revelation 14:6-12)
The first angelic announcement is the everlasting gospel with a loud voice to the whole world from mid-air, imploring them to revere and glorify Creator God for His judgment is coming. Using a direct broadcast satellite, SkyAngel went on the air on December 10, 1996 with six television channels and three radio channels. God may have sent an angel, or earthly messengers called missionaries, to proclaim the gospel to those people groups which do not have radio and television.
The second angelic announcement is the fall of the great city Babylon. The capital city of Baghdad is located roughly fifty miles north of the ancient ruins of Babylon in Iraq. Saddam Hussein likened himself to Nebuchadnezzar, and had a desire to be the head of a new Babylonian empire. Training of the 9/11/01 Saudi hijackers was linked to Iraq. People from over 90 nations were killed in that attack. A coalition of nations led by the US attacked Iraq. With "shock and awe" from April 3-12, 2003, Baghdad was subdued.
The third angelic announcement is a warning against worshiping the beast or receiving the mark of the beast or its image. The beast is Islam; it's image is a crescent moon. The Antichrist will arise to lead the Muslims in their take-over of the world. He will declare himself to be god on the Temple Mount and cause many Jews and Christians to be killed. I suspect this will occur before the trumpets and vials.
