God is the sovereign Lord with power and schedule

Revelation 12;1-9
A sign appeared in heaven: a woman clothed with the sun, with the moon under her feet. She was pregnant and was crying out in birth pains and the agony of giving birth.
Another sign appeared in heaven: a great red dragon 
1260 days for the woman, where she has a place prepared by God.
The child who born will rule all the nations with a rod of iron.
War arose in heaven, Michal and his angels fighting against the dragon. And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world - he was thrown down to the earth.
Signs(Ch12-14) : 1)a woman in labour 2) a fiery red dragon 3)a beast from the sea 4) a beast from the earth 5)the Lamb with his people, standing on Mt. Zion 6)Three angels 7) q heavenly reaper, harvesting the earth.
It has been suggested that John may have taken some of the material in these chapters from current myths. If this is so, the application is all his own. He was writing for a persecuted church and these chapters are fill of encouragement to take heart.
Why?
The star-crown woman clothed with the sun stands for God's chosen people, from whom first the Messiah.
Satan the devil, who is the deceiver of the world world. This world is fill with the false talk and cheating.
The devil will be thrown down to the earth, he has not place in heaven.
How?
God is the Sovereign Lord with power and plan!
