Sometimes our eyes just pass over massive statements of doctrine in the bible. Jeremiah 30 makes it startlingly clear who will and who will not go through the Great Tribulation.
Jeremiah. 30.4-6
These are the words which the Lord spoke concerning Israel and Judah
"thus says the Lord
we have heard a cry of panic, of terror and not peace, ask now and see, can a man bear a child?
why then do I see every man with his hand on his loins like a woman in labour? Why has every face turned pale? ....
7 .... Alas for that day is so great, there is none like it, it is even the time of Jacob's trouble BUT
BUT he shall be saved out of it."
Israel according to the flesh is God's firstborn son, spiritual Israel, the church, is the Bride. Both have promises made to them. To the one promises related to the earth, the land. To the other promises relating to heaven.
Here we see it is the woman, the Spouse who must endure the birth pangs The great tribulation. The church is impregnated and must give birth to the new creation, Israel according to the flesh must be converted.
The disciples asked Jesus if He was going to restore the kingdom to Israel at that time and He said the Father will do it in His own time.
God said that He will gather the whole house of Israel back to their land, and leave none of them in the nations anymore, and they shall know the LORD their God from that time forward and He will never hide His face from them again.
Which means Israel will always be in the truth from that point forward so this has to be a future prophesy.
God is going to give world their way for 7 years to rebel against the truth, and when they do then He will end sin on Earth.
The New Age Christ/antichrist shall establish peace in the Middle East and it will pave the way for all Hebrews to go back to the land of Israel for the Gentile nations will see that it happens, and the New Age Christ wants them all back on their land.
The world will be split in to 10 sections, and for the first three and one half years salvation is still available to the world.
When the world follows the New Age Christ and takes his mark then salvation is no longer available to the world and God will then turn to Israel and send them 2 witnesses who will preach to them for the last three and one half years and at the end of that time Israel as a nation will be in the truth.
The Bible says Israel is blinded in part until the fulness of the Gentiles be come in and so all Israel shall be saved.
Some people think the Church replaces Israel but Israel is the Church.
From Abraham to David to Jesus to the millennial reign of Christ to the New Jerusalem it is Israel all the way.
Which the 12 tribes of Israel and the 12 apostles of the Lamb are written in the New Jerusalem.
That is why a Gentile when saved becomes a Jew inward, and is part of the commonwealth of Israel.
The Gentile becomes part of the nation of Israel because it is Israel all the way.
Paul said God has not cast off His people that He once foreknew.
God said if the ordinances in heaven are still in operation the sun, moon, and stars, then His covenant is still with Israel, and they shall never cease to be a nation.
Rev 12:6 And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.
During the first three and one half years Israel as a nation is protected from physical attack.
Rev 12:14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
During the last three and one half years Israel as a nation is protected from physical attack.
But the Jews that turn to Jesus will be persecuted along with the Gentiles that are with Jesus, but Israel as a nation is protected for the 7 years period until the battle of Armageddon which is part of the wrath of God on the world which then they will attack Israel and Jesus will save them.
