I believe all Gentiles who accept Christ as their Savior are grafted in, and have become citizen of Israel by adoption through faith in Christ. But God has not abandoned His people He will return and restore the Jewish people to Himself.
This is what scripture teaches us Romans 11:17-24, Ephesians 2:11-19, and anyone that denies this truth denies God's word.
Dispensationalism is false plain and simple.
oh well we actually disagree then, Because Jesus talks specifically about seed (sperm), also Israel was divided from Judah, there were two kingdoms, two lands, two tribes, one was Judah including Benjamin and the other was Israel consisting of the ten tribes who scattered after Assyrian captivity, only a remnant reterned to the northern kingdom of Israel, now Judea was seperate, so you are getting the two mixed up for beginners. Read my thread 'Who are the Gentiles' for knowledge on this.
In regard to Eph 2:11-19. the
ethnos (Gentiles) which means in Greek and Latin 'Gens' and proper English 'Genteel of high noble birth of the same tribe, genus, gene, gentle, gentry', it means of the same tribe, so the children of Israel were divided and Israel (ten tribes) were divorced and were taken into captivity and then scattered, the scattered sheep of Israel, surely you must be familiar with this term, Jesus said 'I come only for the lost sheep of Israel'. As you can read - "And that He might reconcile both (Judah and Israel) unto God in one body (Christ) by the cross, having slain enimity thereby"... "For He is our peace, Who hath broken down the middle wall between us;"
apallotrioo (alien) means 'estranged away' from the
politeia - community, citizenship, reconcile means to bring back that which was estranged, cast out as the 10 tribes of Israel was, but now as Paul says in Christ by the cross they are united as Christians, first the Gospel was to go to Judah and then to Israel whom are called
ethnos, Jesus was from Judah but came from the land of the
ethnos (Gentiles) Jesus was from
Galilee of the Gentiles, When you graft it needs to be of the same stock that why Israel can be grafted back into Judah.
Now Israel was divorced in
Jer. 8:3 - "I have put her away and given her a bill of divorce"
So we have the bride divorced, and then the remarriage according to God's own law of his Christian bride whom is saved Israel. And this divorce is also given in Isaiah 50:1 and Hosea 2:2!
Now legally the man dies, God married to Israel after the divorce in the form of Jesus Christ the divorced man dies, therefore allowing Israel to remarry, thus the charge of Adultery cannot be brought agsinst God, for remarrying Israel by the cross, her first husband had to die, after the cross, burial and ressurrection the husband is reunited with his first wife Israel, House of Israel is able to remarry as the bride, thus reconciling the connection between the formerly divorced house of God.
Isaiah chapter 40+ explains the coming of Christ and his relationship with Israel, same moredetailed account given in Hosea.
