I'm not sure what you're trying to say here but Descartes was not a proponent of Solipsism. It was just a thought experiment about validity of proof. To date there's no philosopher, (or scientist or psychologist) who has seriously floated the idea that the Solipsism is even worth considering. I'd say it's a gross simplification of what Descartes was trying to say and is purely in the realm of science fiction. Schrödinger wasn't a proponent of Solipsism either in spite of his cat.
So how do you know god is omnipotent? It's a pretty basic part of Christianity isn't it?
erm...but with this insight then you know you can't know if god had a reason for creating us, can you? Seriously, god does not want us to know jack shit. If god wanted us to know anything about anything it would make an effort. Right now it feels more like it's trying it's damndest to make it as confusing as possible. A little bit like it would be if god never said or did anything and all we're doing is guessing. Sometimes when things are mysterious, they're mysterious because there's nothing to find. You know, like a cigar might just be a cigar.
You're not exactly putting up a fight here. It's as if you've accepted that your faith is arbitrary. I'd have expected a little bit more here.
But isn't the fact that you are Christian in spite of your insights, proof that your aren't willing to look at arguments and learn?
Again. You agree that we can't know but still make a leap of faith. But you deny it is a blind leap of faith. Ermmm.... does this make sense to anybody or am I just a bit slow.
edit: My problem with Christianity is that it is four distinct faiths.
1) The belief in the supernatural.
2) The belief in a personal omnipotent god which judges you when you die.
3) The stories in the Bible and the claims they make.
4) The moral and ethical guidelines and rules.
None of these are in any way connected and there's no reason to believe in one just because you believe in the other. If you believe in the omnipotent being, there's no way of knowing what it wants, is there? I mean, besides making baseless assumptions
