The Woman in Revelation 12
When Jesus appeared to the apostle John, who was in exile on the Isle of Patmos, Jesus came with the words "Write the things which you have seen and the things which are, and the things which must be after these" (Revelation 1:19). By this time John was an old man and out of circulation.
Jesus first tackled the things that are; how the 7 churches had fallen into decline (Revelation chapters 2 and 3) and what John must do about it by warning the churches through letters. Next, Jesus tackled the things which must occur hereafter; i.e. everything that follows chapter 3 in Revelation is for the future!
The appearance of the Woman shining with the glory of the Sun in Revelation 12 is a future event. Many Christians have been deceived to believe that she is Mary, crowned with 12 stars and queen of heaven, Mother of God giving birth to baby Jesus. Why would the risen Lord of Lords want to be born again as a baby?
Revelation 12:1 is a symbolic representation of the glorification of the Bride of Christ bringing forth offspring to the glory of God - her harvest of souls, represented symbolically as a man-child, coming forth according to the given evangelistic mission of the Bride and the Holy Spirit towards the time of the end, "And the Spirit and the bride say, “Come”. And let him that hears say, “Come”. And let him that is thirsty come; and whosoever will, let him take of the water of life freely" (Revelation 22:17). She and the Holy Spirit will be on a world-wide mission that involves much labour!
Why is her offspring collectively called a 'man-child'? It is because her offspring come with authority that will cause Michael, the archangel, together with his angelic host, to cast Satan forever from heavenly places where he has been accusing the redeemed night and day before the Father (Revelation 12:7-10). Therefore, Satan comes down with great fury to bring about the Great Tribulation of the world ruling through the Antichrist 666.
As far as Christians are concerned, the only power Satan will be given by God is to overcome a group known as "the remnant of her seed which have the testimony of Jesus Christ" (Revelation 12:17; 13:7, 15; 14: 10-11). These are the ones who did not allow the Holy Spirit to lead them while they had the chance!
