Not cool if the first hypothesis on sun and moon is wrong.
The blowing of trumpet was to indicate His presence e.g.Exodus 19-20, to give warning e.g. Ezekiel 33 or to assemble e.g. Numbers 10.
I thought we had to get familiar with the physical sound of shofat for the last days but I was wrong.
The prophets gave much warning to the people prior to the invasions of the Assyrian and Babylonian armies in the old testament. It will be the same in the end of times when I believe we are in now. Reason? The Assyrians and the Babylonians were His tools to punish the apostate Israel. Today nonbelievers step all over the apostate church and to survive the church must compromise not unlike the old times.
Then again the Messiah said "watch out that no one deceives you."
Mark 13 some have interpreted the fig tree as the re-born Israel nation but offer no explanation to "all the trees" in Luke 21:29-31. Of course many nations gained independence since 1948 but is it what "all the trees" are about?
Arguments of metaphor sun, moon and stars in Revelations 6:12-13:
Genesis 37:9-10...I had another dream....the sun and moon and eleven stars were bowing down to me...His father rebuked him and said..."will your mother and I and your brothers actually come and bow down to the ground before you?
Sun, moon and stars here referred to people.
Job 38:7...while the morning stars sang together and all the angels shouted for joy.
Isaiah 14:12 How you have fallen from heaven. O morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!
Daniel 10:13 But the prince of the Persian kingdom resisted me twenty-one days. Then Michael, one of the chief princes, came to help me, because I was detained there with the king of Persia.
Revelation 22:16 I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the off spring of David, and the bright Morning Star.
These verses may suggest that the stars are the sons of God. The rise and fall of kingdoms on earth are somehow determined in heaven by the stars.
Psalm 121:6 the sun will not harm you by day, nor the moon by night.
Would the psalmist be referring to the two great lights God created - or - hostile nations represented by sun and moon?
more to come...
