I wouldn't worry about the whole 70-year stuff brother as per the TIME CLOCK. It is an erroneous understanding. Look at the Parable of the FigTree, what does it really say? It says whatever Generation sees ALL THESE SIGNS, thus what were the signs and who saw the LAST SIGN Jesus gave? It's just that simple.
The Temples destruction, the Earthquakes, the Famine, the Wars, the Sorrows. The fake christs of verse 5, the false prophets of verse 11 the AoD of verse 15, the Troubles of verse 21, THE Anti-Christ and False Prophet of verse 24.
AND finally, the Sun and Moon go dark in verses 29-31, so that is the LAST SIGN Jesus gives us about what happens just before his Second Coming? It's the 70th Week Asteroid Impact as seen in Rev. chapter 8, that causes the Sun and Moon to go dark !! Thus the GENERATION that sees the Asteroid Impact in the middle of the 70th week will be THAT GENERATION (of Jews) that sees Jesus return 3 1/2 years later to save them, OF COURSE !!
We overthink these things, to be honest.
These shemitas may very well have a pace in God's thinking, but we can understand what THAT GENERATION is by looking at all the signs brother Blain.
By 2035 Jesus will be ruling with an Iron Rod on this earth. Pastor Jimmy Evans seems to think all of the wicked who survive will be made to live under Jesus Iron Rd of rule for 1000 years, then when Satan is released they follow their god of mischief once again !! To be honest, I would love to see these know it all liberal, wicked men of today gave to serve under Jesus Christ Iron Rule for 1000 years, that would be so funny to me. Oh well, I hope he's right. Jesus rule will be proof their utopia was our ignorance.
