The term "God" could also mean something like= all incomprehensible goodness. All patterns of goodness which can’t be explained or understood! The more someone believes in God, the more they will encounter effortless synchronicity with good events. God is a pattern of good which we cannot figure out. It is a mystery. It has nothing to do with a white bearded fellow sitting on a throne granting wishes-- unless that is how you like to see your god.
When someone stops believing in God (i.e. general concept), they stop believing the force “into” their Life or experience. They stop connecting to that “invisible” pattern of goodness. That is why when someone stops accepting or believing, they will usually throw their self into a pattern of increased negativity, negative emotions, negative circumstances and bad experiences. This further fuels their rage and disbelief in any god and the discourse continues, via the power of belief-- via the law of attraction.
I thought I would throw in my 2 cents on the question--thanks.
Your idea of God displays two false concepts.
the first is that the universe we live in is not 'all good', and when I say 'good' I mean what people define as 'good'. there are many 'bad' things that are an essential part of existence, and both the believers and the non believers may be caught in the circumstances of this flow of events.
the second false assumption which is an extension of the first one, is that unlike your theory, in reality, people who believe in God may just have as hard time as an atheist might or might not have. are you really claiming that only people who lack belief in God, enter a worm hole of negative karma?
