Also Elin, looking some of what you've said. God did separate Israel from gentiles, but
He also allowed gentiles to join Israel.
He also allowed gentiles to join Israel.
Joining Israel does not equate to Israel mixing it up with unbelieving Gentiles.
NB: The law was the wall of partition separating and causing the enmity between Jew and Gentile,
whom Jesus reconciled on the cross (Eph 2:14) by abolishing that law in his flesh (Eph 2:15). . .
and thereby also reconciling the one body of Jew and Gentile to God (Eph 2:16).
