Greetings!
1)Is the Jewish god same as Christian or Islamic God?Or vice versa?
2)Is that god present in its creation.i.e is it omnipresent?
3)IS it Omnipotent.Can it kill Satan or other evil creatures?
1. There is only one God, known by many different names in the various languages and cultures! A few of these include Dieu, Boge, Wankantanka, Gott, Parvardegar, Bug, Allah, and Dios. And He is responsible for all the great religions, which are all successive stages in a single evolving faith, the Faith of God!
2. Yes.
3. Yes.
However there is no "devil" or other negative power out there competing with God: God is Supreme, One, and has no rival or equal!
Further, "satan" is merely a term for our own lower (animal) nature when we give it control instead of our higher (spiritual) nature.
Peace,
