Is There a Limit to the Absolute?

Theist and naturalists alike are both going to be forced to posit some kind of brute act, an unexplained part of reality. And so the question is, why would we ot for god as our stopping point instead of just the physical universe? I think that some theories provide a better account for this than others. Just seems, from all that i can tell, that if te foundation of things is perfect, then that gives you the deepest explanatory account, most depth. It's the simplest.
