i really like this a lot its very simple and to the point but in a profound way. one small suggestion..perhaps if you are denying the existence of god the 'G' should not be capitalized, which usually denotes reverence and respect towards a deity which presumably actually exists.
well the reason i capitalize the "G" is so the reader knows im talking about the christian God whereas god with a small "g" usually refers to like mythological greek/roman/whichever dieties (not that christian beliefs arent also myths :) ) i have no respect for the christian God but i want you to know how im pissing on
