Everything that will take place after Israel has returned to the land and has control of Jerusalem. Jerusalem is represented by the fig tree in the parable of the fig tree.
.
Luk 21:29-31
29) And he spake to them a parable; Behold the fig tree, and all the trees;
30) When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand.
31) So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
32) Verily I say unto you, This generation shall not pass away, till all be fulfilled.
Who then are the other trees, because it says in (30) When they now shoot forth, if you basing your belief on a 1948 date, then what other Countries became Nations at the same time Israel did.
Notice in (30-31) that Jesus says.
Jesus was speaking to these people specifically.
ye see and know of
your own selves that summer is now nigh at hand.
Then Jesus says it again, explaining to them it's the Kingdom of God, not the Nation which he is speaking about.
So likewise ye, when ye see these things come to pass,
know ye that the kingdom of God is nigh at hand.
Then take notice in (31-32)
Jesus was speaking to these people specifically
So likewise ye, when ye see these things come to pass,
Verily I say unto you, This generation shall not pass away, till all be fulfilled.
You can't just pick Israel out of the TREES just because you only read one account of the Parable.
Mat 24:32-34
32) Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh:
33) So likewise ye, when ye shall see all these things, know that it is near, even at the doors.
34) Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
The end of it all is Jesus was speaking to those people who were That Generation which would see and experience the things which were coming.
