As gentile believers in His finished work, it is important to know how we relate to Israel and the Jews. God has not forgotten the Jews and will come back for them- it will be an exciting time. Hallelujah.
11 Again I ask: Did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgression, salvation has come to the Gentiles to make Israel envious. 12 But if their transgression means riches for the world, and their loss means riches for the Gentiles, how much greater riches will their full inclusion bring!
13 I am talking to you Gentiles. Inasmuch as I am the apostle to the Gentiles, I take pride in my ministry 14 in the hope that I may somehow arouse my own people to envy and save some of them. 15 For if their rejection brought reconciliation to the world, what will their acceptance be but life from the dead? 16 If the part of the dough offered as firstfruits is holy, then the whole batch is holy; if the root is holy, so are the branches.
22 Notice how God is both kind and severe. He is severe toward those who disobeyed, but kind to you if you continue to trust in his kindness. But if you stop trusting, you also will be cut off. 23 And if the people of Israel turn from their unbelief, they will be grafted in again, for God has the power to graft them back into the tree. 24 You, by nature, were a branch cut from a wild olive tree. So if God was willing to do something contrary to nature by grafting you into his cultivated tree, he will be far more eager to graft the original branches back into the tree where they belong.
25 I want you to understand this mystery, dear brothers and sisters,[g] so that you will not feel proud about yourselves. Some of the people of Israel have hard hearts, but this will last only until the full number of Gentiles comes to Christ. 26 And so all Israel will be saved. As the Scriptures say,
“The one who rescues will come from Jerusalem,[h]
and he will turn Israel[i] away from ungodliness.
27 And this is my covenant with them,
that I will take away their sins.”[j]
28 Many of the people of Israel are now enemies of the Good News, and this benefits you Gentiles. Yet they are still the people he loves because he chose their ancestors Abraham, Isaac, and Jacob. 29 For God’s gifts and his call can never be withdrawn. 30 Once, you Gentiles were rebels against God, but when the people of Israel rebelled against him, God was merciful to you instead. 31 Now they are the rebels, and God’s mercy has come to you so that they, too, will share[k] in God’s mercy. 32 For God has imprisoned everyone in disobedience so he could have mercy on everyone.
I have posted here an article on Romans 11 showing that God has not forgotten people of Israel. We as the church, the gentile believers of His finished work must know how we are to relate to Israel and the Jewish people. We are encouraged to extend the gospel to our Jewish brothers.
Some take away facts as gentile believers in relation to Israel and Jewish people :
1.Let us not become arrogant as we are wild olive branch sharing in the nourishing sap of the cultivated olive tree root (v 17,24).
2.The reason why the gospel is extended to the gentiles is to provoke the Jews into envy and save some Jews (v 11).
3.When Jews come back to God, hear what God says :
For if their(Jews) rejection brought reconciliation to the world(for gentiles), what will their (Jews) acceptance be but life from the dead? (v.14) . But if their (Jew) transgression means riches for the world (for gentiles), and their (Jew) loss means riches for the Gentiles, how much greater riches will their full inclusion bring!(v12).
4. God has not forgotten Israel as He chose their ancestors Abraham, Isaac, and Jacob (v 28).
5. Some of the people of Israel have hard hearts, but this will last only until the full number of Gentiles comes to Christ. And so all Israel will be saved.(v25,26). .....So let us share the gospel to our gentile unbelievers until the full number comes to the Lord, then all Israel will be saved.

Rejoice. Be encouraged to share the gospel to the gentiles as well as the Jews.
