Let's see. He can't return until about 2064 because Israel won't be a nation again, in God's eyes, until then. They are having a 2000 year sabbatical that started in Acts of the Apostles 28:28 , 64AD, when the Salvation of God was taken from them, for severe unbelief, and given to us Gentiles. Since all OT prophecy involves Israel and, since there is no Israel, no prophecy can be fulfilled during this present 100% Gentile, 2000 years period. So, He definitely won't return in the next 46 years
The 70 weeks, 490 years, of Daniel started in 405 BC, at the dedication of the temple. Therefore, it should have ended in 85AD. However, when Israel became Loammi, "not my people" in 64AD, time stopped, as far as Israel and any prophecy is concerned. Therefore, Daniel's prophecy had 21 years left in 64AD.
The Great Tribulation takes up the last 3-1/2 years of Daniel's 70 weeks. Christ's parousia, His second Coming, occurs at the end of the tribulation, 21 years after Israel is back on the scene.
Therefore, the second Coming of Jesus Christ will occur 46 + 21 = 67 years from now, in 2085, exactly 2000 years later than it should have occurred.
A possible fly in the ointment is the fact that Jesus Christ said in Matthew 23:39 that He would not return until Israel accepted Him as the Messiah. If you read Acts of the Apostles 3:19-20 carefully, you'll see it says, essentially, the same thing. However, I have faith that Israel will quickly accept Christ this time around, after their well-deserved 2000 year punishment, and things will be back on schedule.
Under any possible circumstances, though, He can't return in the next 46 years.
