A unsaved Jew today is like an unsaved Gentile, they both die as such.
A saved Jew today is like a saved Gentile, they both die in Christ, as Christians.
Now, The Lord told the Jews that they needed to be 'born again' and could not count on their being 'sons of Abraham' for their salvation.

After the end of the Church age, it will go back to the way it was before the church age began, there will be saved and unsaved Jews and saved and unsaved Gentiles.
