Correction:
The “seven year tribulation” is one of the eschatologies that is overcome by events. The only sure sign is the Revelation 12:1-2 Great Sign in the Heavens on September 23-24, 2017. That was over five years ago. Total Eclipse that put the first stroke of a X over the USA in August 2017. The final stroke comes in April 2027. That is almost a ten year separation.
The sign you are talking about happens one evry 12 years as Jupiter has a 12 year orbit and the same “signs” happen once every twelve years or so. They were talking about this in 2002 and 1990. John was speaking of something different; something truly visionary and symbolic yet spiritually grounded and real at the same time; but not planetary conjunctions and motions. Jupiter takes 12 years to go through all 12 astronomical houses and enters Virgo once every 12 years.
Rev 10:11 And he said unto me, Thou must prophesy again before many peoples, and nations, and tongues, and kings.I think the second prophecy begins at Revelation 11:19. Unlike the Bethlehem star which cold be seen at night, the sign of Revelation 12:1-2 could not be seen. You cannot see the moon when it is next to the sun. You could not see the war in heaven either (vs 7).
Amos 8:11 Behold, the days come, saith the Lord GOD, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the LORD:Will there be seven years of plenty before this famine? Is that where we are now where everyone can look at the Bible on their phone at any time? Not many people knew about the seven years of plenty. God did not tell Jacob.
