The Revelation 12 sign shows a woman in labor. The birth of the man child happens before the labor in Isaiah, but she is in labor in Revelation. Does this mean the sign is post rapture? Possibly. I give the reasons why it is possible.
Comet C/2017 E1 has never visited our solar system before. It has an orbit of over 100000 years. It is in our system now and is heading out to space quickly. However, last year, it passed through Leo then exited Virgo's womb on the exact day Jupiter entered it. Coincidence?
