Romans 11: 25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. 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. 28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the father's sakes. 29 For the gifts and calling of God are without repentance.
”until the fullness of the Gentiles come in” should give you a hint that it means God is not finished dealing with Israel as His chosen people for the gifts and calling of God are without repentance” meaning God called them to be His people and He will not repent of that. Those who think that Israel has been replaced or superseded are in for a rude awakening.
Which concerns our redemption how? God can do what he wants with the Jews I suppose. If all we have to do is confess that Christ is the Savior (the minimalist understanding) then the fate of the Jewish people is completely irrelevant to us. Except for those who make a hobby of quarterbacking end times prophecy.
P.S.: The Church is the New Israel.
