Just some thoughts... The classic argument is simply that god is supposed to be all knowing, all powerful, and all good. So how come there is suffer ring and pain in this world? Why does god allow it? Obviously if god is all good, then should think that this is bad that all occurs, but rather it wouldn't occur, like any decent person would, yet he lets it occur. Now that would be fine if he didn't have the power to not let it occur, yet god is meant to be all powerful. We're told by religious people that he intervenes all the time. So why doesn't he intervene to prevent the death of a child or torture of a prisoner, etc? He doesn't do it. So, you could conclude from that that god is actually quite bad. But what you can conclude from this is that the combination of these two characteristics are simply inconsistent. He's all good. He's all powerful, and of course he's all knowing, because he knows it going to occur. The standard reply to this from the apologist Christians, is that god created humans with free will, so evil can occur. But why would god do this knowing that these would be the results. That's pretty horrific coming from a person with compassion, so even at that we know it was a horrible decision to come to on his part. So let's put the standard reply aside for a minute. The problem is that not all the suffering in this world comes from the exercise of human free will. Natural catastrophes, disease, accidents, all sorts of things can cause suffering. A child being born with a genetic disease, no humans had any free will role in the outcome of creating this situation. That comes from nature, god's creation, of course we're told. So god created a world in which suffering is inevitable for human beings. The argument to that would be that god created the obstacle course for humans in order to bring out the best in humans. So you have the innocent child with some horrible disease and god is up there saying "I really need to test some people here, let me pick on this newborn child. Let's put them through this terrible ordeal and I'll test her close family." If any human being had the power to do that and said what they've done that they wanted in their wisdom to test some people, to improve their morale character, you would think they are the most wicked person in the world to do that. Then if that's what god does then why have any respect toward him whatsoever. I certainly don't. It's a wicked thing to do.
