God is not “finished” with national Israel, even though there’s a “partial hardening” until the fullness of the Gentiles come to faith (Rom 11:25), and then “all Israel will be saved” (Rom 11:26). The Church is actually made a part of she’arit Israel - the faithful remnant of Israel (Rom 11:17), and not the other way around.
It’s important to keep this distinction in mind between God’s faithfulness to she’arit yisrael and the secular (and often corrupt) government of men that are there ruling the place (think of the schemes of Olmert, for example).
This implies, among other things, that the secular state is not to be identified with any form of theocracy and does not itself hold any sacred status. God is sovereign over all the nations, including secular Israel, of course, but the secular state of Israel is actually a part of the acharit hayamim (end times) theater of operations. This is evidenced by many of the New World Order designs found on secular Israel’s governmental buildings, most particularly the Israeli Supreme Court building.
The Messiah of evil will come and deceive many in Israel as their long-awaited Mashiach. Perhaps he will finally broker true peace in the Middle East. But he will ultimately betray the Jewish people, much like Haman did (or as the Greek Antiochus Epiphanies did), causing the Jewish people to flee for their lives.
Only after the Jewish people cry out, Baruch habah b’shem Adonai in reference to the true Messiah, Jesus, will Israel be saved during this period of Great Tribulation (Matt. 23:29; Luke 13:35). Then shall the prophecy of Zechariah be fulfilled: “I will pour out upon the kingship of David and the population of Jerusalem a spirit of grace and supplication so that they will look to me, the one they have pierced. They will lament for him as one laments for an only son, and there will be a bitter cry for him like the bitter cry for a firstborn” (Zech 12:10).
I am aware that many in the Gentile Church who are “preterists,” “amillenialists,” “dominionists,” “theonomists,” “covenant theologians,” etc. will strongly disagree with my views of the end times, but their thinking derives from faulty assumptions, exegetical fallacies, and errors that are lead inexorably to the false doctrine of Replacement Theology.
