Dangerous old chap,
Apologies for my tardy response. This is mainly down to the fact that I am certainly no philosopher and in fact, have never really interacted with ‘God’ or ‘faith’ from a philosophical standpoint. Although I experienced a definite, ‘one-minute-I-thought-it-was-a-load-of-rubbish-the-next-I-believed,’ conversion to Christianity, I guess my Christian upbringing had prepared me to accept the Christian God unthinkingly in a sense and I was used to a kind of authoritarian, top-down belief in an afterlife and a deity. That said, many many people do ask questions about faith in a philosophical manner, so you raise some very worthy questions, which I will attempt to tackle.
I think God certainly exists and flourishes independent of anything around him, whether that be his creation or his dwelling place (wherever or whatever that may be). He is the pure essence of goodness, graciousness and so on and much of these attributes are expressed within the Trinity, towards the other parts of the Godhead (as a British preacher has clumsily put it: ‘God’s a community’).
So I see it that everything within God’s creation is an expression of these attributes. Of course this raises the question of how evil (or at least the choice to do evil) could have been created by a good God, but my answer to this would go something like this: true, free love involves the possibility to choose not to love. So God created beings with the freedom to walk away from him, which they duly did and God already had a rescue plan up his sleeve.
Aside from Trinitarian theology (the argument that God exists as three, so that love and grace can exist within him, as the three members of the Godhead express their love for one another), there has to also be the possibility that ‘there are others.’ In the Bible, we have the story of how God made and reached out to the inhabitants of our world. But what if there are other worlds, other spheres, other beings we know nothing of and within which God existed and exists quite separate from us? So much of the Bible is God saying to us, “my ways are above yours…now you see dimly, one day you’ll see in full.” What if there are other modes of operation, other levels of the universe which we have yet to discover and perhaps never will, til the end?
