The dualistic notion of a powerful anti-G=d figure who fights with G-d for the destiny of the human race is a Chrstian idea (possibly originating in Zoroa-sterianism, the dominant religion in the Middle East at the time of the founding of Chrstianity.) It is entirely unacceptable to Judaism.

Judaism teaches that there are no competing powers. God is completely in control.

The above is from the Aish article posted by Sophiee. I am always amazed when I read these sort of comments coming from Jews. It's like they have no idea about what Christianity believes. There is no dualistic notion of an powerful anti-God figure on equal footing with God. We do believe that Satan wants to become like God and be worshiped. And that he is out to destroy the human race and individual souls and especially the Jews. But the Christian bible is without debate totally clear beyond any question the future of Satan and that is he will be cast into the lake of fire. Revelation 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
In Christianity, God is in complete control as well. You can ask any Christian that.

Nonetheless, the author was pretty astute in noting that the ultimate destruction of Satan is a central theme in Christian end times beliefs...completely different than Judaism. Also, something that Judaism of course can't agree with, and that is a major part of the end times picture, I would say on equal emphasis as the destruction of Satan, according to Christianity is to bring the Jews to accept Jesus as the messiah. It won't be by us Christians proselytizing to make it happen....so the pressure is not on us to be successful in converting Jews, like you guys think.
