Romans 11: 25 I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in. 26 And so all Israel will be saved, as it is written: "The deliverer will come from Zion; he will turn godlessness away from Jacob. 27 And this is[6] my covenant with them when I take away their sins."[7] 28 As far as the gospel is concerned, they are enemies on your account; but as far as election is concerned, they are loved on account of the patriarchs, 29 for God's gifts and his call are irrevocable. 30 Just as you who were at one time disobedient to God have now received mercy as a result of their disobedience, 31 so they too have now become disobedient in order that they too may now[8] receive mercy as a result of God's mercy to you. 32 For God has bound all men over to disobedience so that he may have mercy on them all.
Of course they are. The "call" was rejected:
"Then Paul and Barnabas answered them (the Jews) boldly: "We had to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we now turn to the Gentiles." [NIV Acts 13:46]
