Option 1 - the ultimate reality behind everything that exists (the ultimate cause) is personal (e.g., a God of some kind). "Theists" hold this worldview.
Option 2 - the ultimate reality which explains everything else is impersonal (e.g., a force of some kind). "Atheists" hold this worldview.
Option 3 - we cannot know whether the ultimate reality which explains everything else is personal or impersonal. Many "Agnostics" hold this worldview.
As far as I can see, there isn't an obvious fourth option. Laying it out like this is helpful in a number of ways. Let me give two examples.
Firstly, atheists sometimes claim they don't have a positive belief (and therefore don't need to provide evidence for their atheism). But atheism is a positive belief: if you deny the claim that the ultimate reality behind everything else is personal (God) you are affirming that the ultimate cause of everything is impersonal.
In light of things like genuine personal consciousness (which can't easily be explained in terms of impersonal forces and impersonal matter alone), option 2 cannot simply be assumed (with rational integrity). Indeed, many argue (contrary to both option 2 and option 3) that various features of the Universe point unequivocally to a personal cause (as I do).
Secondly, atheists have sometimes challenged those who believe in God with the question: "who created God?" - as if that single-handedly demolishes their belief-system. What the three options above make clear is that the question is nonsensical. As one philosopher has put it, it effectively asks: "what caused the first uncaused cause?" The answer ("nothing, obviously") is self-evident.
Hard as it is to wrap your mind around, all worldviews have to accept there must be some ultimate explanation behind everything else - that's a given.
So we come back to our original question: is that ultimate reality personal or not?
In my view, the belief (I once professed) that ultimate reality is impersonal can't be squared with the evidence and ultimately stems from a very personal desire to turn away from God which makes the denial of his existence very attractive (see the quotation in my talk on Faith and Doubt).
But what if we've got God wrong? What if the suffering we see in the world is not evidence that he is evil, but of something else? What if God, for all his terrifying power, is good and glorious? What if turning away from him is the source of all our problems not the solution? What if he's the kind of God who loves us treasonous godless rebels so much he would become one of us and suffer the terrible punishment our treason deserves so that we can be forgiven and reconciled to him? What if Jesus, who in various ways claimed to be God in human form, really is what God is like? What then?
Then we'd have no more need to cling to options 2 and 3. Then we could embrace the God from whom every good thing comes - and find life.
