Hello Brakelite.
There are certainly two different entities in the New Testament, physical Israel and the Gentiles.
Of this the scripture is very clear and is beyond debate Brakelite. Where I experience difficulty
is chapter 11 of Romans.
Romans 11
25 For I do not want you, brethren, to be uninformed of this mystery, so that you will not
be wise in your own estimation, that a partial hardening has happened to Israel until the
fullness of the Gentiles has come in;
This verse is very straight forward, Paul explains that the hardening applied to physical Israel
by God will soften one day. That day is a future day after the fullness of the Gentiles is reached.
How do you read this verse Brakelite?
In the beginning God made Adam, the father of the human race. Adam was the son of God (Luke3:38); therefore all his descendants are by right God's people. He did not cast them off because theysinned. His love embraced the world (John 3:16), and it did not contract in the days of Abraham, Isaac,and Jacob. The only advantage of Israel was that they had the privilege of carrying the glorious gospel to the Gentiles, for whom it was always designed as much as for them.
The Gentiles, as well as the descendants of Jacob, were from the beginning intended to become Israel. This was shown at the conference in Jerusalem. Peter told how he had been divinely sent to preach the gospel to them, and that God put no difference between them and the Jews. Then James said: "Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name. And to this agree the words of the prophets; as it is written, After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up; that the residue of men might seek after the Lord, and all the Gentiles,upon whom my name is called, saith the Lord, who doeth all these things. Known unto God are all his works from the beginning of the world." Acts 15:14-18. See also Amos 9:11-15.
From the above we learn that the "tabernacle of David," the house or kingdom of David, is to be restored through the preaching of the gospel to the Gentiles, and that this is according to the mind of the Lord from the beginning of the world. What these scriptures need is not comment, but believing thought.
"Blindness in part is happened to Israel, until the fulness of the Gentiles be come in." Rom. 11:25. Until the fulness of the Gentiles "be come" into what place? Into Israel, of
course; for it is by the bringing in of the fulness of the Gentiles that "all Israel shall be saved."
When will the fulness of the Gentiles "be come" in?
The Lord himself furnishes the answer: "This gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come." Matt. 24:14. God is visiting the Gentiles, "to take out of them a people for his name." By them Israel is to be made full or complete. As soon as this work of preaching the gospel to the Gentiles is finished, then the end will come. There will then be no more preaching to anybody, not to the Gentiles, because they will all have made the final decision; and not to the Jews, because then "all Israel shall be saved." There will then be no more need of the gospel; it will have accomplished its work.
Romans 11:27-36
27 For this is my covenant unto them, when I shall take away their sins. 29 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 29 For the gifts and calling of God are without repentance. 30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: 31 even so have these also now not believed, that through your mercy they also may obtain mercy. 32 For God hath concluded them all in unbelief, that he might have mercy upon all. 33 O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out! 34 For who hath known the mind of the Lord? or who hath been his counselor? 35 Or who hath first given to him, and it shall be recompensed unto him again? 36 For of him, and through him, and to him, are all things: to whom be glory for ever. Amen.
Note carefully verses 25-27. When the fulness of the Gentiles shall have been brought in, "all Israel shall be saved." Indeed,
it is only by the bringing in of the Gentiles that all Israel will be saved. And this will be a fulfillment of that which is written, "There shall come out of Zion the Deliverer, and shall turn away ungodliness from Jacob." Only through Christ can Israel be saved and gathered; and all who are Christ's are Israel; for "if ye be Christ's then are ye Abraham's seed, and heirs according to the promise." Gal. 3:29.
To consider any other option, for example that
all literal Israel will be saved, brings with it connotations of universalism; for if the grace and mercy of God allows literal Israel to grafted back into their own tree by any other means than through Christ, then surely one might argue that if God were to be just, and to be not the respecter of persons that the scriptures testify to, then why not all the Gentiles also?
