No, he didn't you just do not understand the bible Randyk, THIS GENERATION is referring to the generation that sees ALL THE SIGNS, thus the LAST SIGN being the Sun and Moon going dark means the Jews who see the 70th-week SIGN will be THAT GENERATION who sees Jesus' return. Of course !! We agreed on very little on the other board, so I doubt you will start seeing these truths now, but hope springs eternal.
1) Jesus was speaking to his own Disciples in his own generation.
2) Jesus had just finished berating his own generation of Jews, who rejected him as Messiah, and who used the Law to disguise their internal wickedness.
3) Jesus said the temple would literally fall, stone by stone. That happened in that generation.
When you recognize that Jesus was clearly referring to his own time, and to the soon-coming judgment for his own wicked generation, then you can understand what Jesus meant by "all these signs." He obviously was not referring to the sign of his 2nd Coming, since he excluded that from any prediction of time and circumstance.
But Jesus had just finished explaining the things that would happen leading up to the fall of the temple. These signs, including rumblings of war, were called "birth pains." And they all happened in Jesus' generation, just before the fall of Jerusalem to the Romans.
It was "all these things" that would take place in "this generation." Jesus was predicting the time of Israel's fall, and not the time of his 2nd Coming.
