Jesus told us:
15 "Therefore when you see the 'abomination of desolation,' spoken of by Daniel the prophet, standing in the holy place" (whoever reads, let him understand), 16 then let those who are in Judea flee to the mountains. 17 Let him who is on the housetop not go down to take anything out of his house. 18 And let him who is in the field not go back to get his clothes. 19 But woe to those who are pregnant and to those who are nursing babies in those days! 20 And pray that your flight may not be in winter or on the Sabbath. (Matt. 24)20 "But when you see Jerusalem surrounded by armies, then know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her. 22 For these are the days of vengeance, that all things which are written may be fulfilled. 23 But woe to those who are pregnant and to those who are nursing babies in those days! For there will be great distress in the land and wrath upon this people. 24 And they will fall by the edge of the sword, and be led away captive into all nations. (Luke 21)
The parallel between the two passages is undeniable. It is the AD70 event. The abomination/Jerusalem surrounded by armies was a localized event in the region of Judea. The "abomination" involved the ultimate desecration and desolation of the temple. This was not some future nuclear holocaust. People had time to gather their belongings and get out of the city. The Christians did just that, as Jesus had warned them to do.
Nor is there any need to rebuilt the temple, resurrect the long decayed Levitical priesthood, or reconstruct the Roman empire, as futurist anticipate.
No, the answer is quite simple, and that generation understood Jesus’ prophecy.
No -- only one of those passages was fulfilled in the months leading up to 70 AD. The other is still future.
The "abomination" involved the ultimate desecration and desolation of the temple.
But just how could that be in your scenario. If they had fled when they saw the armies surrounding Jerusalem, then they wouldn't have been there at all to see the temple destroyed. But those who did see the temple destroyed then were all killed. They never had a chance to flee. It was already too late for them. So the destruction of the temple couldn't possible be that abomination that Jesus spoke of.
Furthermore according to Daniel 9, the abomination of desolation is to occur in the middle of the 70th week of Daniel, which you preterists claim ended in 33 AD. So your abomination of desolation would have been way back there around 30-33 AD. Can you tell us just what event took place then that could be interpreted to be the abomination of desolation???
