By the way, Matthew 24:29-31 talks about Jesus returning to gather His elect. Who are "His elect" at this point in time? The only elect I know of at that time, when Jesus said these things, are the Jews. There was no Church then. Isaiah 45:4 seems to mention "...Israel mine elect". If, perhaps Christ comes for His Church (also called His Bride, The Body, Flock,etc.) before the Tribulaiton, then it would seem logical that He would come back for "His elect" at a later time, perhaps after the purging and cleansing of the tribulation that causes "His elect", i.e. Isreal, to repent and accept Jesus Christ as their messiah.
