The short answer to your question is no. Quite the contrary, in this passage, which begins with Paul’s stalking horse question in Romans 9:30-33, Paul is indicating that the gentiles who have been grafted into Israel through faith in Messiah Y'shua will provoke Israel to jealousy causing Israel (the nation) to receive “the deliverer” who will come from Zion (Messiah Y'shua). It is He and only He who will remove ungodliness from (Israel) Jacob [Romans 11:26]. In that verse, Paul quotes:
Isaiah 59:20-21 (NASB)
20 "A Redeemer will come to Zion, And to those who turn from transgression in Jacob," declares the LORD. 21 "As for Me, this is My covenant with them," says the LORD: "My Spirit which is upon you, and My words which I have put in your mouth shall not depart from your mouth, nor from the mouth of your offspring, nor from the mouth of your offspring's offspring," says the LORD, "from now and forever."
In this passage, Isaiah is referring to Messiah Y'shua. Since Messiah has come in the flesh and died for our sins, the only way to “turn from transgression” is to accept the propitiation of the atoning sacrifice He made on our behalf. This is true for Jews and Gentiles alike, and in Romans 11, Paul is reminding the Gentiles he is writing to that Israel is the source of our salvation, not vice versa.
Interestingly, when Paul uses the phrase, “that a partial hardening has happened to Israel until the fullness of the Gentiles has come in” (Roman’s 11:25); he is not referring to the “church age” as most Christian theologians suppose, but is in fact alluding to the blessing of Isaac upon Joseph’s son Ephraim. Although Manasseh was the older of Joseph’s two sons, Isaac had placed his right hand on Ephraim, the youngest as he blessed them. When Joseph tried to correct his father by placing Isaac’s right hand on Manasseh, Isaac:
“… refused and said, "I know, my son, I know; he (Manasseh) also will become a people (am: people; as in “am Y’srael” [the people of Israel]) and he also will be great. However, his younger brother (Ephraim) shall be greater than he, and his descendants shall become a multitude of nations (goyim)." (Genesis 48:19)
It should be noted that Isaac used the word “am” (people) regarding Menasseh and the word “goy” (gentiles or nations) regarding Ephraim. The words translated “multitude of nations” in Genesis 48:19 should be translated “fullness of the gentiles”, the exact words Paul uses in Romans 11:25. The Hebrew phrase גּוֹיִם מְלוֹא “melo goyim (literally fullness of the gentiles) can also be rendered “what fills the gentiles” What Isaac was prophesying in this verse was that Ephraim’s descendants would fill the gentiles and become so mixed in with them that they would lose their Hebrew identity. That is exactly what happened when Assyria dispersed the northern Kingdom, known at that time as “Ephraim” throughout the known world, so mixing them in with the gentiles that they don’t know that they are Abraham’s descendants.
Paul is not saying here that Israel will be saved when the gentile “church age” runs its course. Instead he is alluding to a time prophesied by Ezekiel, when Israel (the northern Kingdom known as Ephraim which has been disbursed throughout and thoroughly mixed in with the gentiles) will be reunited with Judah in the land that Yahveh promised to Avraham. In our time, Judah has returned to the Land of Israel, but Ephraim has not.
Ezekiel 37:15-28 (NASB)
15 The word of the LORD came again to me saying, 16 "And you, son of man, take for yourself one stick and write on it, 'For Judah and for the sons of Israel, his companions'; then take another stick and write on it, 'For Joseph, the stick of Ephraim and all the house of Israel, his companions.' 17 "Then join them for yourself one to another into one stick, that they may become one in your hand. 18 "When the sons of your people speak to you saying, 'Will you not declare to us what you mean by these?' 19 say to them, 'Thus says the Lord GOD, "Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel, his companions; and I will put them with it, with the stick of Judah, and make them one stick, and they will be one in My hand."' 20 "The sticks on which you write will be in your hand before their eyes. 21 "Say to them, 'Thus says the Lord GOD, "Behold, I will take the sons of Israel (not Judah) from among the nations (goyim) where they have gone, and I will gather them from every side and bring them into their own land; 22 and I will make them one nation in the land, on the mountains of Israel; and one king will be king for all of them; and they will no longer be two nations and no longer be divided into two kingdoms. 23 "They will no longer defile themselves with their idols, or with their detestable things, or with any of their transgressions; but I will deliver them from all their dwelling places in which they have sinned, and will cleanse them. And they will be My people, and I will be their God. 24 "My servant David (refers to Messiah, not David) will be king over them, and they will all have one shepherd; and they will walk in My ordinances and keep My statutes and observe them. 25 "They will live on the land that I gave to Jacob My servant, in which your fathers lived; and they will live on it, they, and their sons and their sons' sons, forever; and David My servant will be their prince forever. 26 "I will make a covenant of peace with them; it will be an everlasting covenant with them. And I will place them and multiply them, and will set My sanctuary in their midst forever. 27 "My dwelling place also will be with them; and I will be their God, and they will be My people. 28 "And the nations will know that I am the LORD who sanctifies Israel, when My sanctuary is in their midst forever."'"
The covenant mentioned in verse 26 is the same covenant Jeremiah prophesied about from which we get the term “New Covenant or New Testament”:
Jeremiah 31:31-34 (NASB)
31 "Behold, days are coming," declares the LORD, "when I will make a new covenant with the house of Israel (also known as Ephraim) and with the house of Judah, 32 not like the covenant which I made with their fathers in the day I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them," declares the LORD. 33 "But this is the covenant which I will make with the house of Israel after those days," declares the LORD, "I will put My law within them and on their heart I will write it; and I will be their God, and they shall be My people. 34 "They will not teach again, each man his neighbor and each man his brother, saying, 'Know the LORD,' for they will all know Me, from the least of them to the greatest of them," declares the LORD, "for I will forgive their iniquity, and their sin I will remember no more."
It should be noted that the new covenant is made with Judah and Israel, not Judah and the gentiles. We gentile believers enter into the new covenant only when we become grafted into Israel by accepting her Messiah!
Back to your question; I believe that someday, when the Messianic believers of Ephraim are miraculously called out of the nations and reunited with Judah in the Land of Israel, the blessing of Yahveh upon them, evidenced by the power of the Holy Spirit manifested through them, will provoke the jealousy of all of unbelieving Israel to the point that all of Israel will be saved by accepting Y'shua as their Messiah! Paul is in no way implying in Romans 11 that there will come a time when Israel will be saved apart from accepting the sacrifice Messiah made to atone for their sin. But Paul is also reminding gentile believers in Messiah not to be arrogant about Israel’s “hardening in part” which resulted in our being saved. Furthermore he reminds gentile believers in Messiah that our inclusion in the New Covenant is the result of being grafted into Israel through faith in Israel’s Messiah.
Even today many Jews are being made jealous by gentiles who are being drawn back to their Hebrew roots. This is why it is so important that gentile believers who are being drawn to keep Yahveh’s Appointed Times (the Feasts of Leviticus 23), do so publicly. God is drawing us into His purpose in this regard in answer to Paul’s prayer in Romans 10:1, that Israel might be saved. The Jews are made even more jealous when the promise of the Father (the baptism in the Holy Spirit), which was made to Israel, is manifested through gentiles who have accepted Y'shua as the Jewish Messiah. This is why it is so important that we covet the manifestations (gifts) of the Holy Spirit and walk in His power. To the extent that the church neglects to encourage believers to keep the Feasts and walk in the power of the Holy Spirit; it stands against Yahveh’s end times purpose of provoking Israel to the jealousy which will draw them to Messiah Y'shua.
