Here are the simple answers to your ridiculous questions, that are going to make you fall on your knees like a fuckin' baby :
1º Because God (Christ) wants to test our faith. If He was regenerating amputees legs, like it was nothing, then everybody would believe in Him and so it would be easy for everybody to be accepted in the Kingdom of God. He only cures sicknesses who aren't visible from the outside in order for guys like you to still doubt and wonder if wasn't the after effect of medical treatment.
2º Because our world (this world) belongs to satan, our world is already hell (for me). Nothing good or at least almost nothing good comes out of this world! If people are dying from hunger then it's just a coincidence (unfortunately for them). Some regions had no luck. That's just it. Those desperate little children do not pray to God I believe. They don't even know Jesus Christ.
3º I've never read the whole Bible so.... but from my point of view, God wants those good people to die because Heaven is better than earth right? It's logical, you are the one being unlogical. Like for example if I was sure that because of what I did on this life (accept and believe in God), I would most certainly go to Heaven, then I would gladly exchange my position with my grandmother's who is dying, what I mean is I would want to be in her place because she is about to die and not live the rest of my miserable life in this planet !! Do you understand?
4º Have you ever seen any dinosaurs?? Yet you believe in them because some freaky white- haired scientific in the mid 20's or whatever told the planet so. Well the same goes for God. You haven't seen him but you have not seen the dinosaurs either, so why would you believe one and not the other?? What the fuck dude!! Are you stupid??
5º I didn't know the Bible encouraged slavery. I don't know where you got that. Maybe because you're an atheist, you misinterpretated the Holy Book.
6º Again it's just a coincidence if good people were rewarded on earth then there would be no difficulty in believing in God and gaining access to Heaven, there must be a challenge somewhere right?!
7º Again if evidence was found it would be too easy.
8º Because it would be too simple to just pray and Jesus appearing etc... again the same bullshit!! Prayers don't work all the time!! It wouldn't be fair for someone to see Jesus in a vision and not us right?!
9º I don't know why, but when you think of it, it's not that disgusting, it's just bread and wine!! Don't do it if you don't want!! Just believe in him!!
10º What stupid question is that??!! Because it depends of the people, not of God!! If you get divorced it's your problem, not God's fault.
By the way, this "kind of rationalization" christians are making may be true, but you must understand that christians are not GOD. Some christians say bullshit, some others say the Truth like me for example. Some are fanatics some aren't, you see what I mean. Some atheists have different opinions than you right?? So don't come with your bullshit.
By the way the world we live in that you like so much will end or in 2012 because of the rumors of polar shift or planet X or mid 30-40, because of the global warming which will cause 6 degrees more to deal with on our planet and that will end human kind. So think again you peace of shit and start reading the Bible, if you want to save your ass. Watch these videos, 2nd one may be too difficult for you to understand but we never know right??!! :
