I am not speaking now about the baby in the manger 2,000 years ago. Rather the present burden has to do with the Christ who is being born today.
A great and wondrous sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head. She was pregnant and cried out in pain as she was about to give birth. (Revelation 12:1,2)
The woman is the Christian Church. The sun represents righteousness. The moon signifies that fact that to the Church has been given authority over the material creation. The crown of twelve stars represents the twelve tribes of Israel.
The Church is about to give birth to the Body of Christ. This travail is beginning today, or is reaching its climax today.
Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on his heads. (Revelation 12:3)
Notice that the Church is in Heaven and Satan is in Heaven. When the Lord Jesus told us to pray that God's will would be done in earth as it is in Heaven, He did not mean that God's will is being done in Heaven. He meant that God's will would be done in Heaven when it is done in the earth.
As in Heaven, so on the earth---this sort of thing. Whatever you bind on the earth shall be bound in Heaven.
It is obvious, in Chapter Twelve, that God's will is not being done in Heaven. Satan has access to God and is able to accuse the saints. This is not God's will. Satan is not removed from his heavenly vantage point until Michael and his angels drive Satan and his angels from their position.
