Are you saying that God doesn't exist because there is evil in the world?
No. I'm saying it's mighty odd that God is willing to forewarn us about a flood, but not 9/11. Arguments about free will and how God wouldn't intervene, are negated: God is evidently quite willing to intervene when he issues various warnings in the OT stories (Don't eat the fruit, build an ark, the ten commandments, etc). God was quite vocal way back when, but he's conspicuously silent now. Even those who claim he speaks to them can't offer anything tangible to substantiate their divine revelation - it's all ifs and buts and maybes and vagaries.
I'm not saying this fundamentally disproves God, and I'm certainly not pointing out the problem of evil. I'm just highlighting an incongruity between God's behaviour in the myths and legends of the OT, and his behaviour in the modern era.
Secondly, God can exist even thought there are natural disasters...
Greg Koukl - Why does God allow natural disasters? - YouTube
That video is rather distasteful. It appears he's saying pain and suffering are either subjective and inconsequential (playing down international inequalities in quality of living as simply culture shock) or a necessary consequence (earthquakes are a necessary and unavoidable part of God's design). Both of these theodicies have rather glaring problems.
First, it's not culture shock to pity the African who's starving, or the Malay who can't get running water, or the Thai who can't afford live-saving vaccines. That's a genuine problem in the world that causes unnecessary suffering. It's not culture shock, it's genuine, unnecessary suffering.
Second, the suffering caused by earthquakes is not a necessary function of God's design: God could quite easily design the world
without earthquakes. He could easily step in and recycle the Earth's crust as and when needed, thus preventing any unnecessary suffering caused by natural events. When God is all-powerful, he doesn't need to rely on a mechanical, natural system. And even if he does, he doesn't need to build one that causes so much suffering - if
I can think of a better, painless system, then so too can God.
So, the two theodicies presented by Koukl don't solve anything, and instead just insult those who genuinely are suffering.
