In Romans 11:25-36, the apostle Paul reveals that something mysterious has happened to the Jews that has led to the salvation of the Gentiles. The Jews have been "hardened" or made unreceptive of God's "good news." This came about through their rejection of their Messiah, and now God has turned to the "other sheep" that Jesus spoke about just before his crucifixion. Those "other sheep" are now those to whom the apostle Paul has been appointed, the Gentiles. God's ministry to them, although not totally exclusive of some Messianic Jews who will be redeemed, as well, is His focus until "the fullness of the Gentiles" is complete. That will be followed-up by a mass conversion of Jews at the end of human history on earth.
