What does Romans 11:31 mean?
Paul is repeating one of the main themes of this chapter. He is saying once more to the Gentile Christians that, though they were disobedient and did not deserve it, they received mercy from God. This is true, in part, because of Israel's disobedience in rejecting Christ.Does that mean that the Gentile Christians should be done with Israel? Should they mock Israel? Paul insists that they do not. Israel is in a season of disobedience to the gospel of Christ now, just as the Gentiles were—and for the most part still are—in a season of rejection of God. One day, however, Israel's people will see the mercy shown to the disobedient Gentiles, believe in Christ, and turn to receive mercy from God, as well.
Paul has described this as God making Israel jealous of His now special relationship with believing Gentiles in order to provoke some Jewish people to return to Him through faith in Christ and be included in that relationship (Romans 11:11–14).
