Yes it did.
No it didn’t. Your quote from Zechariah 12 has not happened yet either. The Old Testament and the New Testament are in 100% agreement here, which is one of the agreements that vexes atheists so much. Thank God for that! :-)
The Preterist view is very unattractive to me. It pretty much says that Jerusalem is finished, that the founding of Israel in 1948 meant nothing in a historical sense, and that the persecution of Jews in the past 2 centuries means nothing now since the proper Kingdom of God has finally come.
That’s repugnant to me. There is more to be done before we can declare our work as Christians completed.
There is to be a new heaven and a new earth and the old one are to pass away (Revelation 21:21). There is no need for this if the current state of affairs is now all right with the Lord.
There is going to be a horrible global tribulation where Christians are persecuted for refusing to do what the atheists tell them - us - to do. Israel has nuclear bombs, and soon, many of the Middle Eastern countries will have them as well, and they don’t have the inhibitions the West has had in using them.
If Israel gets hit with nukes, they’re going to return fire. The Book of Isaiah leads me to believe that Israel’s target will be Syria - Damascus.
And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened.
And this shall be the plague wherewith the Lord will smite all the people that have fought against Jerusalem; their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth.
Yes, it did:
And following Him was a large crowd of the people, and of women who were mourning and lamenting Him. But Jesus turning to them said, "Daughters of Jerusalem, stop weeping for Me, but weep for yourselves and for your children. "For behold, the days are coming when they will say, 'Blessed are the barren, and the wombs that never bore, and the breasts that never nursed.' "Then they will begin TO SAY TO THE MOUNTAINS, 'FALL ON US,' AND TO THE HILLS, 'COVER US.' Luke 23:27-30
This was fulfilled in the events leading up to the destruction of Jerusalem, and it's that destruction about which Zechariah prophesied. And here is verse 30's parallel in Revelation:
Then the kings of the earth [land] and the great men and the commanders and the rich and the strong and every slave and free man hid themselves in the caves and among the rocks of the mountains; and they *said to the mountains and to the rocks, "Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb; for the great day of their wrath has come, and who is able to stand?" Revelation 6:15-17
You can choose to ignore the evidence all you wish, but it won't hasten Christ's return because He already appeared to that generation: the generation that crucified Him and persecuted His apostles.
That is what the NT actually teaches.
