We don't know when, but we do know that we are now more than 73 years from the establishment of the State of Israel in 1948, and from the "parable of the fig tree" in both the Tanakh (Old Testament) and New Testament, we are the "generation" to see all end time events fulfilled!   The hour is late in these End Times!   Sadly so many churches and pastors avoid the topic of end time Bible prophecy, and that actually fulfills Scripture:

Matthew 24:39 states, ".......AND THEY DID NOT UNDERSTAND UNTIL THE FLOOD CAME AND TOOK THEM ALL AWAY; SO SHALL THE COMING OF THE SON OF MAN BE."

P.S.   Psalm 102:16 King James states, "WHEN THE LORD SHALL BUILD UP ZION (Israel), HE SHALL APPEAR IN HIS GLORY" -------- RAPTURE FIRST, AND A LITTLE MORE THAN 7 YEARS LATER THE SECOND COMING!   Just in case anyone does not know, prior to Israel's return in 1948, the last time the Jewish people were a free nation in their own land was 721 BC when Assyria came down from the north and took the northern 10 tribes of Israel captive.
