This seems to be a question that all religious believers ask, when life fucks up beyond belief. It also happens when people lose a partner or one of their family. My point is, why pose the question to an entity that does not exist? That's just plain fucking stupid.
Occassionally, people question why I don't believe in god. Mmm - that'll be on account of the fact that no 'all-seeing, omnipotent' being could not oversee such misery as exists in this world without sending a few thunderbolts up peoples arses or turning them into hedgehogs or something. What's the point of being a god if you can't do clever stuff like saying 'Shazam - size of a slug'?.
"But it's a test of our faith" whinge the pathetic mother-fuckers that believe in this shit.
Well, it might test your faith, all it does for me is to confirm my belief that there is no god. Even if there was one, he'd be a wanker for putting so many people through such misery.
*Tip from Goth World*
Pretend to be like a 'boy-scout' and always be prepared. Have a small penknife ready to stab any intruding god in the calf and say something clever like "All seeing? Didn't see that coming did you omni-present fucker?!" and then laugh as god hobbles around going "ow, that fucking hurt".
Anyhow, the point is not to ask god "Why have you forsaken me?" - just ask the bastard what he was doing when the shit hit the fan. I bet the tosser comes up with some excuse about trying to fix the fjords in Norway or something.
You may have a better idea why he/she/it was busy???
