The Jewish religion in it`s various forms , operated for 4,000 years before Christianity arrived.
The Jew`s are recognized by Christians, and Jehovah`s Witnesses ( and Muslims ) even today, as being God`s chosen people . In all that time ,Being instructed , directed ,and blessed by GOD , and also chastised by him , in a personal relationship , that has not in the same way occurred in 2,000 years of Christianity .
Google the Jews view of Satan and contrast it with the Christian view of Satan.
So whose view of Satan should you believe , the Jews who had direct contact with the almighty GOD himself ? or Christians who have no claim to such a direct relationship with the Almighty GOD .
