Quoted By:
The prophecy of the Woman from Revelations 12:1 has come to pass, revealing to this generation that the bible is Astro-Theology. It makes reference to astrological alignments, as well as portray the truth, and a way of life, to the reader.
In this case, "A sign appeared in the heavens" is literal, and is to be taken to mean Astrological alignment.
The alignment to look for after that shall be revealed to you by placing yourself in the shoes of a child born in ancient Greece or Rome. They had an expansive mythology that correlated with astrological phenomena, featuring the names of constellations.
