My problem with the above is that the term 'God' is thereby rendered superfluous and even unhelpful - as is often the case with term-dilution.Spinoza felt that God was so intrinsic with everything that he often substituted "Nature" for God. In this case, "Nature" means virtually everything. So, a way of phrasing this approach can be summed up this way: "What is, Is".
I tend to take the position that whatever caused our universe/multiverse I'll call "God" and pretty much leave it at that. To me, there's simply not enough information for me to take it any further, so why should I guess. Or, to put it another way: "Whatever happened, Happened".
If the term is to have any value whatsoever, I think it must minimally signify preternaturel Agency and posit intentionality.
