It isn't going to be Jesus with one kind of body and ourselves with another. Scripture speaks of: "...the Lord, Jesus Christ, Who will transfigure the body of our humiliation, to conform it to the body of His glory, in accord with the operation which enables Him even to subject all to Himself. (Php 3:20-21, CLV) There will be differences in degrees of glory, "...for star is excelling star in glory. Thus also is the resurrection of the dead.(1 Cor 15:41-42, CLV) There's nothing in Scripture promising an earthly reward to people who are racially "Jewish" and a heavenly reward to those who are racially "Gentiles." Not only is there no such thing as a "Jewish" race, having intermarried from earliest times, "Judaism" is and always was a religion. God never was a racist. That, "The flesh profits nothing" is not anything new. "Not all are Israel that are of Israel." "...those of faith, these are sons of Abraham." (Ga 3:7, CLV) We gentiles goyim or,nations, are grafted into the same tree and are now true "Jews."
"For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God." (Rm 2:28-29, AV)
"For not that which is apparent is the Jew, nor yet that which is apparent in flesh is circumcision; but that which is hidden is the Jew, and circumcision is of the heart, in spirit, not in letter, whose applause is not of men, but of God." (Rm 2:28-29, CLV)
