Isn't that the truth? It really is the quick and easy guide to God. I know, I know, logic hurts. It's painful, but it's gotta be done. Theists will go down the arguments in this chart, and conclude that "God works in mysterious ways." Well, that's just bullshit. If he is almighty, all knowing and all good, working mysteriously serves no point. It is just a cop out that theists give God; they try to pretend that all the pain and suffering is part of a Master Plan. God is all knowing, all powerful and all good? Ok, fine. Take a look at this picture:
Look at it. Really look at it. If you are a theist, understand that the God you believe in sees this too. He knows about it, and all the other horrors of the world.
He sees this too. He knows about it, and he can change it, but he doesn't. He is so powerful and so loving, that he does nothing.
If he was lonely and created us, he could have made us to be completely perfect. He could have designed the world in any number of ways that would have not made suffering and evil possible. If you had the power God has, wouldn't you abolish suffering? Or would you keep it around, just to be mysterious, because it works into some nebulous Master Plan concept?
If that's God's plan, it sucks. I don't care how powerful and loving he is--if this is the best he can do, God is either not very powerful or a complete sadistic asshole. Under what circumstances is it ok to allow these things to occur? None.
If there were a man who knew about his child being repeatedly stabbed, for example, and this man could put a stop to the stabbing and immediately heal all his wounds, but he just... didn't... we would be outraged. The morality is the same. God doesn't get his own custom morality unless you want to believe that morality is relative. But since God's law is eternal, unchanging and just, I doubt many theists believe that morality is relative (and for the record, I don't either, but for different reasons).
Is God willing to prevent evil, but not able? Then He is not omnipotent.
Is He able, but not willing? Then He is malevolent.
Is He both able and willing? Then whence cometh evil?
Is He neither able nor willing? Then why call Him God? - Epicurus
