Jesus said the generation that witnesses the fig tree restored, or the rebirth of Israel in a day would see all of scripture fulfilled. So with a starting point anywhere from late 1947 to May of 1948 being the restoration, everything including the rapture, 7 year tribulation, and 2nd coming should happen by 2028.
The years of our life are seventy, or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone, and we fly away.
According to Psalm 90:10, 80 seems to be the maximum number of years a generation can last. Adding 80 to 1948 gets us to 2028 and then subtracting out Daniel's 70th Week aka The Time of Jacob's Trouble, the rapture would have to take place by 2021. That's actually the time that the covenant of the final 7 years would be confirmed. It seems more likely to me that the rapture would happen before that when all is "normal" as in the days of Noah, then there would be a time of confusion, reorganization, sacrifice reinstituted, construction on the 3rd temple begins, the world government would be formed with its antichrist leader, then the covenant would be confirmed by him.
Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy. Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate. Daniel 9:24-27
I am very weary as I'm sure many of you are. The fact that 2019 is here and the covenant would need to be confirmed by 2021 gives me a lot of hope for the rapture to take place any time up until then. Hope it brings encouragement to you all as well.
