@Vanderhoven, the scriptures say that Jerusalem will be trampled on by the nations until the appointed times of the nations are fulfilled.
Do you think the fulfillment on "Jerusalem" is only on the literal city?
If you think Jesus just meant the literal city of Jerusalem, then do you think the appointed times of the nations is still going on since Jerusalem the literal city has never been free from "Gentiles"? Do you think that the Messiah will come back and rescue the literal Jews from the nations and give then a literal kingdom on earth in the physical nation of Israel?
The first century alone was not what Jesus was talking about.
Part of the fulfillment was the destruction of the literal temple in Jerusalem. But the trampling of "Jerusalem" and the great tribulation that has not occurred since the world's beginning until now, no, nor will occur again, is on the figurative "Jerusalem". Jesus wasn't giving that prophecy to warn the literal Jews. The literal Jews didn't listen to him. He was giving the warning to Christians.
The trampling of the figurative "Jerusalem" hasn't happened yet. The appointed times of the nations hasn't even begun yet. It will begin soon, and then there will be greater distress than ever in the history of mankind.
The conclusion of the appointed times will be 3 1/2 years after it starts. (A time, times and half a time. The same as 42 months mentioned in Revelation. The same as the three and a half times in Daniel.)
At the end of the appointed times of the nations, Jesus will come on clouds from heaven with great glory and his enemies will see him. Jesus is "pierced" today when people persecute his followers. When it says "even those who pierced him" will see him, it means they'll know Jesus is coming. They'll see him, just like people saw him go up in the clouds when he went to heaven in the first century.
"Flee to the mountains" when you see the UN (the disgusting thing causing desolation) in the vicinity of "Jerusalem". Jehovah and Jesus are our "mountains" - they are our mountainlike refuge, our relationship with them is a stronghold for us.
When the UN attacks the religious institutions, Jehovah and Jesus will be our strong tower. There won't be church buildings and church leaders anymore. We will have to show brotherly love to each other and help each other get through. When Jesus said, "Do you love me?" Peter replied, "Lord, I have affection for you." Jesus said, "Shepherd my little lambs."
