I disagree.. Today the Jewish people are predominantly of the belief that the messiah is still going to come.
There are messianic Jews.. but the majority are not..
It is these that will believe and be converted during the tribulation...
I believe the distinction between Christian and 'Messianic Jews' is insulting to God. There is no special title or status for believers who are Jewish. The apostle rightly says,
"For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him" (Romans 10:12). The Gentile is treated the same as the Jew, and vise versa, in Jesus Christ.
We have become one, Jew and Gentile, in Christ. The first Christians were Jewish, and Jesus called her the 'Church,' not 'Israel.' We are the true, spiritual Israel that carnal, ethnic Israel foreshadowed. They were blessed with physical blessings in the land God promised to their fathers, but it was pointing to a far better covenant that promised eternal blessings promised to their fathers as well. Abraham saw Christ and the end of his covenant in Christ. Israel was used to bring about Christ and the New Covenant, so that this salvation would go throughout the whole world. For at one time (the Old Testament period) the gospel was concealed in shadows and types, and was understood chiefly by the elect within Israel. David was a believer of the New Covenant to come, by faith in the promise, while remaining in the Old Covenant that still lingered in his day. However, the Jew who did not believe in God only enjoyed the blessings of the covenant given to their fathers regarding land, prosperity, etc.
The final judgment upon the nation of Israel occurred in 70 AD (and partly in the beginning of the second century), a generation after the crucifixion of Jesus. It was the final blow because of their rebellion. He came to them like a hen for her chicks, but they refused to receive him as a whole. It was the elect among them that follow him, but the nation crucified him through the Romans. So God used the Romans to punish Israel one last time. The Romans brought on the tribulation that some passages referred to, and the 3 1/2 years refers to the destruction of the Jewish people and the siege of Jerusalem. It was the worse tribulation that the Jewish people had ever experienced in their existence as a covenant nation. Of course, there was more rebellions, less as dramatic than this one, decades later led by other 'messiahs' who claimed to be the son of David that finally did away with them for good, whatever was not finished in his burning wrath.
You should really read the account of Josephus, a priest who turned into a rebel who turned into a historian, who survived and was spared by Vespasian and Titus to live. He writes in detail as to what happened during that time. He was in the midst of it, was that not God ordained?
Jesus spoke of the sun, moon and stars falling during the tribulation, symbolic in the Old Testament to kingdoms and their leaders. Jesus may have referred to the fall of the nation to Rome.
Anyways, I am rambling too much on these subjects.
