Matthew 13:30 "Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn."

Could this suggest 'at the same time'? In the twinkling of an eye. [I Cor 15:52]    We are the wheat.  Mary was the barn for Jesus. I believe that Jesus was conceived on the Hebrew 9th month and 24th day as Haggai suggested [2 Haggai 2:18-19].  That could make his birth Sept 11th as Dr. Ernest L. Martin said in his book "The Star that Astonished the World".

The book by Michael R. Molnar "The Star of Bethlehem" gives the signs occurring in the heavens before his birth.

Doesn’t a pre-tribulation rapture go against scripture because Mat 24:21 is before Mat 24:31.

Matthew 24:21 “For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.”

Matthew 24:31 “And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds [corners], from one end of heaven to the other.”

May you be blessed by you continued indepth study of God's WORD.  JFH
