My reply to a question as to whether the result of the Jews’ unbelief is a permanent falling away from God is, “No! God is saving many non-Jews to make many Jews envious and seek to be saved.”

Romans 11:11-12

11 Perhaps someone will ask, “When the Jews sinned by not believing in Christ, did it result in their separating themselves from God permanently?” Then I would reply, No, they have certainly not separated themselves from God permanently! What is happening is that because they sinned, God is saving non-Jews in order to cause the Jews to envy the way he blesses non-Jews and so ask Christ to save them. 12 When the Jews sinned (OR, rejected Christ), the result was that God abundantly blessed other people in [MTY] the world by offering them the opportunity to believe. And when the Jews failed spiritually, the result was that God abundantly blessed the non-Jews. Since that is true, think how wonderful it will be when the complete number of the Jews whom God has chosen will believe in Christ [RHQ]!
