I do Not believe in replacement theology.
I believe there are those who will be saved through faith in Jesus Christ  (Jews), I also believe there are those Jews who don't believe in Jesus and try to sway others away from faith in Christ. Even in the time that Christ was here he commissioned his disciples to minister to the Jews first. Most rejected him so it was preached to the Gentiles until the fulness of the Gentiles comes in. Then I believe that after the Rapture of Believing Jews and Gentiles the 144,000 Jews will be like John the baptist or Elijah and minister to the lost world, these Jews will be protected by God, Israel /Jews are still the apple of God's eye,His Wife. Concerning the post regarding Nathan, He said he saw that Jesus garments were stained with the blood of Jews. My comment was regarding this scripture. The world that will be judged will include those who say they are Jews and are not along with unbelieving gentiles nations, along with the world religious system. Some Jews will perish if they refuse Jesus.
