In many ways, Allah is the same God of the Christians and the
Jews. The difference between the big three of middle-eastern

Muslims see Jesus as a great prophet, slightly less in stature to
Mohammed.
Jews see Jesus as a prophet, not the Messiah.
Christians proclaim that Jesus is the Messiah.
Ultimately it will point to how redemption is being viewed in the
various religions.
