Existence implies potential non-existence, and implies a potential to be made non-existant.
Any definition of God becomes caught up in boundlessness, inarticulation, and vain supposition.
It is, by prerequisite, rootless, unreferencing, and incomparable. It is a personification of the expression 'anythings possible', the primordal self-negating proclaimation, an unlimited assertion.
A handle, a hanger, a tarbaby, a bludgeon, a vortex within the mind of man.
I used to agree with the following "I don't believe in God, I believe in something much, much bigger".
Now, I wont even go that far, I think of myself as a meta-agnostic: I don't understand what I truly mean when I say 'God'.
Who am I to witness such a thing?
