Bible verses Rev_2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan. Rev_3:9 Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
Rom 2:27 In fact, uncircumcised Gentiles who keep God's law will condemn you Jews who are circumcised and possess God's law but don't obey it. Rom 2:28 For you are not a true Jew just because you were born of Jewish parents or because you have gone through the ceremony of circumcision. Rom 2:29 No, a true Jew is one whose heart is right with God. And true circumcision is not merely obeying the letter of the law; rather, it is a change of heart produced by God's Spirit. And a person with a changed heart seeks praise from God, not from people.
