Will Jewish believers be left behind when the Rapture happens?
No. Jewish believers who are in the Body of Christ will not be left behind at the Rapture. When a Jew believes and comes into the Body of Christ, he loses his distinct identity; Jew and Gentile are all one, so all believers go together.
Les explains that this is part of the mystery now revealed to the Apostle Paul: the Jew loses his identity when he comes into the Body of Christ. He recalls a Jewish lady asking if, since she was a Jew, she would be left behind if the Lord came that night while Gentiles went in the Rapture. Les said, "Heavens no!" If a person is a believer, whether Jew or whatever, and is in the Body of Christ, all go together. She was relieved and comforted that being Jewish did not make her different in the Body of Christ. Les stresses that whether Jews or Gentiles, bond or free, and even nationalistically whether black or white, red or yellow, it makes no difference—all are one when they come into the Body of Christ.
