You fail to understand that it is the NATION Israel that will finally enter into the wedding supper/millennial reign via the New Covenant.
How? National corporate repentance. Thats how.
And then of course, the believing REMNANT of nation Israel will be RECOMISSIONED to undertake the task they formerly abandoned:
To SERVE God as priests to the gentile world. The gentile remnant who survive thru the tribulation.
Hos 5:14
For I will be unto Ephraim as a lion, and as a young lion to the house of Judah: I, even I, will tear and go away; I will take away, and none shall rescue him.
Hos 5:15
I will go and return to my place, till they acknowledge their offence, and seek my face: in their affliction they will seek me early.
Hos 6:1
Come, and let us return unto the LORD: for he hath torn, and he will heal us; he hath smitten, and he will bind us up.
Hos 6:2
After two days will he revive us: in the third day he will raise us up, and we shall live in his sight.

The only Israelis who will be saved are the Israelis who recieve the mark of God in their foreheads.Revelation says there are 144,000.You can disagree all you want but only the Israelis who recieve the mark of God in their foreheads are saved.
Ezekiel 9
9 He cried also in mine ears with a loud voice, saying, Cause them that have charge over the city to draw near, even every man with his destroying weapon in his hand.
2 And, behold, six men came from the way of the higher gate, which lieth toward the north, and every man a slaughter weapon in his hand; and one man among them was clothed with linen, with a writer's inkhorn by his side: and they went in, and stood beside the brasen altar.
3 And the glory of the God of Israel was gone up from the cherub, whereupon he was, to the threshold of the house. And he called to the man clothed with linen, which had the writer's inkhorn by his side;
4 And the Lord said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof.
5 And to the others he said in mine hearing, Go ye after him through the city, and smite: let not your eye spare, neither have ye pity:
6 Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at my sanctuary. Then they began at the ancient men which were before the house.
7 And he said unto them, Defile the house, and fill the courts with the slain: go ye forth. And they went forth, and slew in the city.
8 And it came to pass, while they were slaying them, and I was left, that I fell upon my face, and cried, and said, Ah Lord God! wilt thou destroy all the residue of Israel in thy pouring out of thy fury upon Jerusalem?
9 Then said he unto me, The iniquity of the house of Israel and Judah is exceeding great, and the land is full of blood, and the city full of perverseness: for they say, The Lord hath forsaken the earth, and the Lord seeth not.
10 And as for me also, mine eye shall not spare, neither will I have pity, but I will recompense their way upon their head.
11 And, behold, the man clothed with linen, which had the inkhorn by his side, reported the matter, saying, I have done as thou hast commanded me.
Revelation 14:1
Then I looked, and there before me was the Lamb, standing on Mount Zion, and with him 144,000 who had his name and his Father’s name written on their foreheads.
144,000 is roughly 2 percent of Israel's population.Roughly the same percentage of christians in Israel today.
The rest will be receiving the mark of the beast which they serve today.
