Yes, but it does not say that there is no eternal redemption for the Gentiles. It still just shows that Israel maintains a special place before God. This is what you are missing. Salvation in Christ is present for everyone. Salvation is by grace as Peter says in Acts 15:11. However, he links that to the salvation of the Gentiles and Jews. THat we (Jews) will be saved by the grace of our Lord Jesus Christ, just as... they. (Non-Jewish Gentiles). The point Peter is making is that the Jews are not saved by the covenant or the Law, but by the grace of the Lord Jesus Christ. He doesn't say that the covenant is worthless, but that it isn't for salvation. That land God promised to Israel that they have never had... THEY WILL. It will happen. They will live under God their King for the millennial kingdom, that God might fulfill the promises He made in the Old Testament to Israel. However, non-Hebrew Gentiles are mentioned in those promises and prophecies. They come seeking God through the Jews. This again speaks to the special position of the Jews before God. I have never said they don't have a special position before God.The idea of salvation being administered through a covenant is a central theme in the Bible and speaks clearly of the New Covenant established through Jesus Christ, which brings eternal redemption.
The following verses directly connect God's covenant with the promise of salvation or eternal redemption:
That doesn't limit who will be saved. It does give specific reason to the salvation of the Jews. That is the inheritance of Abraham, which is only a portion of the Earth.The New Covenant and Salvation
The book of Hebrews is particularly explicit about the connection between the New Covenant and salvation:
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance. Hebrews 9:15.
Again, this says nothing about the Gentiles, and doesn't limit salvation to the Jews only. Again, I have already stated that there are differences in the status between Gentiles and Jews. Gentiles are saved by the kindness of God. God's mercy. Non-Hebrew Gentiles who are God fearers, and have come to believe and have faith in Christ benefit in the covenant, but are not part of it. There is soooo much to Abraham's faith, that by God's promise, it overflows to all who have faith. God doesn't say that about the covenant. Just when God says that in Christ, ALL the nations of the world will be blessed. Not will be partakers, but will be blessed. The gospel given to Abraham within a promise given because of the portrayal of the gospel when God replaced Isaac with a ram. It all goes together. None of it had anything to do with Abraham being a Hebrew, but everything to do with his bottomless faith in God. That is why the promise is separate from the covenant.20 Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting ecovenant,
21 Make you perfect in every good work to do his will, working in you that which is wellpleasing in his sight, through Jesus Christ; to whom be glory for ever and ever. Amen. Hebrews 13:20–21.
I would love to see you argue with a Pauline Dispensationalist. It is almost as tiring as arguing with you. Going from someone who says that Gentiles are not part of the covenant (though I have already told you I agree) to someone who clearly states that Jews are not part of the church. Jews are not a part of the body of Christ.6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises. Hebrews 8:5–6.
This does not say the Gentiles aren't saved. Not at all. You have yet to present any such verse.
Now I would like you to know that I am a die hard futurist. I would believe you would already know that. Stop talking about the Mosaic covenant as that is dead and gone. It wasn't even in force when Jesus came. Israel violated that covenant once they ran after false gods. God even spoke at how He was tired of all the sacrifices.God's Covenant with Israel and Future Salvation
Paul also connects the future salvation of Israel with God's covenant promises:
26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
27 For this is my covenant unto them, when I shall take away their sins. Romans 11:26–27.
These verses demonstrate the teaching in the Scripture that salvation (or eternal inheritance/redemption) is secured and administered through God's established covenant—specifically the New Covenant in the blood of Christ.
The Mosaic Covenant clearly established animal substitution sacrifice for the sins of Israel past, present, and future. It was through the Mosaic Covenant through which God and Christ would provide salvation from sin and death. Someone had to die for Israel's sins and as part of the Law of Moses animals were sacrificed yearly on Israel's holiest day (Yom Kippur) for that purpose. From Abel's first substitutionary sacrifice as taught them by God (Gen. 3:21) sin had to be paid for by the death of the sinner. But by the grace of God the Law of Moses commanded the death of the sinner but also through the Law of Moses substitutionary sacrifice was commanded by God to Israel until in the fulness of time God would Himself provide a sacrifice who died for the sins of Israel and this was done through God's own Son, Jesus Christ.
Salvation is offered universally for any who would fear God and believe in His Christ by faith. However, Paul humbled the Jew and the Gentile/Greek by saying that salvation is first to the Jew (humbling the Gentiles), and then to the Gentile (humbling the Jews within the contention that arose between the Jews and the Greeks). However, Paul recognized, as I spoke of above, the special place Israel has before God in that salvation was first to the Jew, then the Greek/Gentile. (non-Hebrew type). The non-Hebrew Gentiles owe their salvation to God first, but also to the Jews. This is what you must understand. Salvation is not simply there for the Jews, however, if you read the back of the book, the final salvation of God's elect within the nation of Israel will be glorious. The Gentiles don't get that. They just receive the kindness of God, and the promise that if they don't remain within that kindness, they will be shut out. For the Jews, unbelief/rejection of Christ shuts them out. Belief brings them in, without warnings of being ejected again. Why? They, as well as all true believers, are held fast by God.
Stop looking at the covenant when looking at salvation. Peter explains what salvation is after rejecting the covenant in salvation. The last two words must not be removed from my statement. Acts 15:10-11. The church is made up of both non-Hebrew Gentiles and Jews. I reject what the Pauline dispensationalists say. All believers in Christ are one in His body, the church. However, with the covenant, with Old Testament prophecy, with the Olivet Discourse in Matthew, with Daniel's 70 weeks and other end times prophecies, with Revelation 19 and Revelation 20, the covenant God made with Israel, and the New Covenant are solid. God will not allow Israel to be destroyed. There is a remnant there still to be saved, and they will be. And as I said before, and I can't help repeating, it will be glorious. I am with Paul's presented emotions when he says what could the salvation of Israel be, but life from the dead. And those in the church, non-Hebrew Gentile, and Jews, will be there to see this glorious "resurrection". (I get that from life from the dead, so I am not saying actual resurrection.)
Christ's inheritance is all of creation. Israel's inheritance is what was promised by God to Abraham. What about the rest? From prophecy, there are Gentiles in those other lands, seeking out God through the Jewish people.
The covenant is not all there is. As you said, the Gentiles do not have a covenant with God. All the God-fearers amongst the non-Hebrew Gentiles have are the blessing of God (Psalms) and the kindness of God (Romans). As Adam was the representative of all humanity, the New Adam is also the representative of all humanity. However, the difference is that the New Adam (Christ) is the representative of all humanity who believe in Him by faith. Jew and Gentile.
