Referring to the Temple buildings, Jesus said to His disciples, "Do you see all these things? Truly I say to you, not one stone shall be left upon another, which will not be torn down."

A.D.33: Three days later Christ appeared to the Apostles and others. He would send THEM what the Father had promised and they would be clothed with power from high. Repentance and forgiveness of sins would be preached in His name TO ALL NATIONS beginning in Jerusalem.

Cestius recalled his soldiers from the place and retired from the city without any reason. (WJ:II.XIX.4-7) The "many" seized by great fear who immediately ran out of the city were following  Jesus' command  made 36 years earlier: When they saw armies surround Jerusalem, when they saw the abomination of desolation at the holy place, they were to drop everything and flee!

A.D.70: Prior to the siege of Jerusalem, many died of famine when they were shut inside the City on the Passover. They were surrounded by Roman troops.

AD.66: The Roman army commanded by the Roman general Cestius marched to Jerusalem with the intent of besieging it. Inside the city, he attempted to break into the temple at its northern quarter. The first rank of Romans rested their shields upon that wall, at which time a great fear seized upon many, who immediately ran out of the city. Cestius recalled his soldiers from the place and retired from the city without any reason. (WJ:II.XIX.4-7) The "many" seized by great fear who immediately ran out of the city were following  Jesus' command  made 36 years earlier: When they saw armies surround Jerusalem, when they saw the abomination of desolation at the holy place, they were to drop everything and flee!

A.D.73: The Romans captured Masada, ending the Jewish wars. (WJ:VII.VIII,IX)

This caused the waves to roar all over the Mediterranean. The ash plume from the eruption moving west to east caused the sun to darken the moon to stop giving its light. All the stars to appeared to fall from the sky. The appearance of falling stars was an optical illusion caused by the movement of the ash plume. Men were stricken with terror.

SIGN #6 - The Son of Man will come in the clouds and send forth His angels to gather His elect.

A.D.79: The Son of Man came in the clouds for all to see. He sent His angels down to gather His elect. 144,000 believers were "taken." They went to the same place as Jesus and dead holy people before them who raised from their graves to life and were taken up to heaven. (Mt.27:52-53) The secular people left behind described giants traversing the skies and the sound of a trumpet (Dio Cassius Bk.LXVI section 22,23). Since John was the only disciple who remained to be taken at this time, no disciples were left to record this event. John's Revelation in A.D. 69 prerecorded many of these events which would take place a few years in their near future, thus completing the biblical story before they were all taken and while some were still around to write it..

SIGN #7 - All the above occurs to the generation to which Jesus is speaking.

A.D.79: All signs described by Jesus happened to the generation to which Jesus spoke some fifty years earlier.

SIGN #8 - Heaven and earth will pass away, but His words will never pass away.

A.D.79: The elect, the 144,000, were "taken." For them, heaven and earth passed away. And then they saw a new heaven and new earth which God the Father prepared for them. The Gospels and letters of the New Testament and Revelation were written down, and the His words never passed away.
