They are Israelites, and to them belong the adoption, the glory, the covenants, the giving of the law, the worship, and the promises.
Romans 9:4

After Yeshua's death and resurrection, Paul wrote that natural Israel remains Israel. The election, covenants, Torah, etc., remain theirs despite anything they might or might not do. Paul unambiguously says Jacob's bloodline matters. Our philosophies and theologies are irrelevant.

Not all who are of Jacob's bloodline nor all who have been adopted by them will be counted among the remnant of #israel, but God decides, not us. The status of any particular Jew in God's Kingdom is nobody's call but God's. Don't presume on your invitation.
