So can you identify the generation you believe Jesus was referring in Matthew 24:34?
First FYI - Jesus said, "There shall not be left here one stone upon another, that shall not be thrown down."
In my research I found that on the Temple Mount there were stones 'one upon one another' for a few hundred years after AD70.
Look at things Jesus says in the chapter.
"Take heed that no man deceive you."
For THEN shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
"For THEN shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be."
This is probably the biggest sign...
WHEN ye therefore shall SEE the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
And this too...
"And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come."
The disciples asked what for signs preceding the parousia.
PAROUSIA - the future visible return from heaven of Jesus, to raise the dead, hold the last judgment, and set up formally and gloriously the kingdom of God.
Jesus went through the trouble to explain which generation. He said it's the generation that SEES/witnesses the passing of the events he mentions in the chapter, and compares that time period/generation to the budding of a fig tree. The leaves budding represent the things he mentions in the chapter that precede summer, and Summer represents Christ return/Parousia is near.
"Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh:
So likewise ye, (In the same way) when ye shall SEE all these things, know that it is near, even at the doors.
Verily I say unto you, This generation shall not pass, till all these things be fulfilled."
There are three different words for END and three different words for world in Mathew 24.
