God is not a Christian.
God is not Jewish.
God is not Islamic.
God is not a Hindu.
God, as the supreme being, monotheistic deity, or creator of the universe, is not a member of any man made, earth bound religion. No single religion/denomination can lay claim that God belongs to them, and them alone. If anything, the exact nature of God is unknown. You can quote whatever holy book that you want, it does not prove anything.
It is important to separate the human conceptions of God from what we can actually observe...which will be difficult, since God does not make personal appearances and has yet to be captured on camera/video. To that end, we have to study nature and the cosmos in order to see God's creation at work and evolving (incidentally that is the core of deism).
God can't be bound in any human system of belief. Nor can God be restricted to one culture or geographic location. The exact details about God are unknown, and will remain so until said deity decides to make a personal appearance at a press conference, and goes through a Q&A session.
