Originally Answered: Jehovahs Witness: Do Jews understand the events on Mt Sinai and the 10 Commandments to indicate a wedding?
Contrary to what the JWs believe, Israel is only temporarily cut off from God, because they were behind the death of Jesus. Of course, God knew all this ahead of time. They haven't lost their promises and they will be restored. God still has an amazing plan of salvation for them. Jesus will be re-identified to the Jews as the promised Messiah and He will accepted as Savior.
I ask, then, has God rejected his people? By no means! For I myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin. God has not rejected his people whom he foreknew. Rom. 11:1, 2a
A wonderful section of Romans 11.
And even they, if they do not continue in their unbelief, will be grafted in, for God has the power to graft them in AGAIN. For if you were cut from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated olive tree, how much more will these, the natural branches, be grafted BACK INTO their own olive tree. Rom. 11:23, 24.
Israel's Salvation - It all works together perfectly so Gentiles could be grafted in.
Lest you be wise in your own sight, I do not want you to be unaware of this mystery, brothers: a partial hardening has come upon Israel, until the fullness of the Gentiles has come in. And in this way all Israel will be saved, as it is written, “The Deliverer will come from Zion, he will banish ungodliness from Jacob” and this will be my covenant with them when I take away their sins.” As regards the gospel, they are enemies for your sake. But as regards election, they are beloved for the sake of their forefathers. For the gifts and the calling of God are irrevocable. For just as you were at one time disobedient to God but now have received mercy because of their disobedience, so they too have now been disobedient in order that by the mercy shown to you they also may now receive mercy. For God has consigned all to disobedience, that he may have mercy on all. Rom. 11:25-32
Restoration of Israel
Other amazing prophecies about the restoration of Israel
Ezekiel...chapter 39 is great.
“Therefore thus says the Lord God: Now I will restore the fortunes of Jacob and have mercy on the whole house of Israel, and I will be jealous for my holy name. They shall forget their shame and all the treachery they have practiced against me, when they dwell securely in their land with none to make them afraid, when I have brought them back from the peoples and gathered them from their enemies' lands, and through them have vindicated my holiness in the sight of many nations. Then they shall know that I am the Lord their God, because I sent them into exile among the nations and then assembled them into their own land. I will leave none of them remaining among the nations anymore. And I will not hide my face anymore from them, when I pour out my Spirit upon the house of Israel, declares the Lord God.” Eze. 39:25-29
That one is amazing because it has already started. God has already started re-gathering the Jews to Israel. We're watching prophecy fulfillment happening right now.
Jews AND Gentiles will be united as one flock, under one Shepherd - Jesus. John 10:16
“‘I know your tribulation and your poverty (but you are rich) and the slander of those who say that they are Jews and are not, but are a synagogue of Satan. Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie—behold, I will make them come and bow down before your feet, and they will learn that I have loved you. Rev. 2:9, 3:9
