Spinoza's God does not represent a 'personal relationship with God.Another thing came to mind...When an American rabbi once asked Einstein, “Do you believe in God?” he replied: “I believe in Spinoza’s God, who reveals Himself in the orderly harmony of what exists.” hmm. It's interesting but I doubt from my reading about Einstein that he thought he could have a personal relationship with that God.
It would be more accurate that Spinoza's God is the natural relationship with our physical existence and humanity.
