You know God exists.This is not a case of belief. This is absolute knowledge. You have factual proof of God's existence. You have seen His works. You have walked in His realms. You have met Him. Every argument against His existence falls apart in the presence of basic truth. God exists. Made the world. And made it -- exactly as it is. Full of hate, full of murder, full of pointless petty evil existing for the sake of hurting others. On purpose. And He sits back and watches it all for the amusement.
You know God exists. You have the proof. And you know He's an asshole.
And you, like everyone else, will be punished in the end for your actions or lack thereof, because everyone gets punished. It's just funnier that way --
-- but there's no way you're going to thank the bastard for it first.
