The Great Red Dragon
” And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.” (Rev 12:3 KJV)
The great red dragon is of course Satan. It is interesting that the dragon is used as a symbol of Satan. In order to be used as a symbol, John had to have known about dragons and dragon legends.
The seven heads could refer to the seven world kingdoms from Egypt, Assyria, Babylon, Media, Persia, Greece, and Rome.
“And she being with child cried, travailing in birth, and pained to be delivered.” (Rev 12:2 KJV)
Many see the child as Jesus. This view would require chapter 12 to be past events which interrupts the sequences of the wrath of God to tell us a history that can only be symbolic and doesn’t fit with the rest of the book or with any historical accounts of the life of Jesus.
