Which Generation "Shall Not Pass"?

Question: Jesus said, “This generation shall not pass, till all these things be fulfilled” (Mat 24:34). How long is a generation? Was that the “generation” that saw Israel restored to her land in 1948? If so, how much more time do we have before the fulfillment of Christ’s prophecy? Aren’t we running out of time?Response: God told Abraham that his descendants would be slaves for “four hundred years” and would enter Canaan “in the fourth generation” (Gen 15:13-16). Was a “generation” 100 years, and thus we have until 2048? Moses said, “The days of our years are threescore years and ten” (Ps 90:10), so had a generation gotten shorter, and we only have to wait until 2018?There is no basis for thinking that Christ meant the “generation” which would see Israel restored to her land. Furthermore, Israel hasn’t been fully restored yet. We know He didn’t mean the generation then alive, for that would have been a false prophecy. Preterists say Nero was the Antichrist, and that “all these things” prophesied by Christ in Matthew 24:1-33 came to pass in AD 70 with the destruction of Jerusalem, and that Israel no longer has any place in the prophetic scheme. Preterism is easily disproved.Christ said a tribulation was coming that would be worse than anything before or after (Mat 24:21). The tribulation of AD 67-70 was nothing compared to Hitler’s slaughter of 6 million Jews. Verse 22 says, “except those days should be shortened, there should no flesh be saved….” Surely there was no danger that the weapons available in AD 70 might wipe out all flesh, nor was the tribulation cut short on that account. Verses 29-31 mention signs in the heavens, including everyone visibly seeing “the Son of man coming...with power and great glory” and the angels “with a great sound of a trumpet...gather[ing] together his elect...from one end of heaven to the other”—none of which occurred in AD 70. The “generation” alive in Christ’s time did not see the fulfillment.
