I don't believe in most of the dogma of religions, especially certain aspects about the Devil, demons and hell. Eternal punishment for temporal acts of ignorance don't seem to make much sense. I'm more spiritual than religious, and believe there's a supreme being, though not this judgmental angry God that is often described. Of course when we see the injustice, loss, pain, suffering and death that exists it becomes difficult to reconcile those experiences with a loving, caring, peaceful creator, but the reasons for these harsh realities will probably be made clear eventually. I'm sure it has something to do with things like natural laws, cause and effect and free will.
Most religions are a limited and superstitious fashion of ancient man trying to describe the divine responsible for life and its unexplainable phenomena. It's likely impossible for a few books, religions or even the sum total of scientific knowledge to completely explain an all encompassing deity.
From my own perspective any supreme being would have to be pure, infinite conscious energy.
People will always ask, "what existed prior to the universe?" And you'd have to conclude the same conscious energy source but in an unmoved state of rest. It was always in a perfect state of stasis and continuous bliss, with no need to do anything other than be. An infinite and timeless Being would always be in the ever present now, with time and space being an observable extension of its energy, possibly from an unobservable dimension, similar to a Higgs field.
The universe could literally be the reflection of an eternal conscious mind. And it is recreating itself from a singular identity into a people or souls. It passes its conscious energy thru the lifespan of a person and rejoins it to itself as a new personality, to become One in Being as a heavenly collective existing in a timeless continuum.
