A lot of the stuff I mentioned above. The idea of Hell though seems to be the biggest thing with me right now. I was raised in an Assemblies of God/Evangelical Christian home (though my mother's bipolar illness and my father's upbringing by alcoholic parents hurt his ability to effectively parent) so I was raised to believe there is a Hell. And there are billions of people (especially of the Islamic "religion") that are going to suffer in eternal damnation.
It's just not sitting well with me right now. Though I am going to have coffee with my pastor in a couple hours so I might bring it up with him as well.
