I
will make those who are of the synagogue of Satan, who claim to be Jews though
they are not, but are liars—I will make them come and fall down at your feet
and acknowledge that I have loved you. Revelation 3:9
The synagogue of Satan doesn’t refer
to all Jews, only the Jewish leadership who was used by Satan to try to stop
the Christian movement in Israel. This
referred specifically to the leadership.
They weren’t really spiritually Jewish (more culturally) or they would
be more open to God.
