First, I should note that all the most common/obvious questions have been thoroughly answered (where thorough refers to length). For many of these questions, you could get a better answer from reading what has already been written about it. Edit: you probably don't want to ask these questions as bluntly as I've worded them.
Why is choice of god mainly determined by which country a person was raised in, like eg language but unlike eg science? Does belief in God help one make more accurate predictions (not "better explanations") than using a secular model?
Why is wisdom praised throughout the Bible, except for a reversal in the New Testament, where standard wisdom is condemned as an opponent to Godly wisdom? Why is it that higher education leads to lower rates of theism, and what is this evidence of?
Why are various good traits assigned to God? For example, why is God considered forgiving if He demands a blood sacrifice (human sacrifice according to Christians) before He can forgive sins? I know humans who can forgive without requiring any sacrifice, nor even a request for forgiveness, remorse, etc. Why is God considered just, when He is willing not only to excuse evildoers, but actually punish the innocent in their place as a sacrifice (and eternally reward people for a trivial thing with no moral value like believing in Jesus)? Why is God considered merciful what with going out of His way to eternally punish people in Hell? I've heard that the answer to this sort of question is that God is holy -- is holiness some sort of terrible character flaw that we must avoid at all costs, or something to be emulated?
Why do people say that Jesus willingly died for our sins, when He clearly didn't (Matthew 26:39) and don't forget that disobeying God is frequently regarded as resulting in eternal damnation. Some people say that Jesus suffered in our place -- shouldn't that mean eternal damnation, not being dead for 3 days? Why can't I die for everyone's sins, or at least my own? Why all the confusion with what exactly "death" means in the Bible, especially if it starts in Genesis 3 yet is prevented by believing in Jesus?
Compare Genesis 3:3-5 vs Genesis 3:22. Why is the serpent considered a liar? Why is God upset at humans knowing good and evil in Genesis, yet elsewhere wants that distinction taught?
Consider the sort of worlds created by humans to interact without other humans -- eg the worlds in which MMORPGs are set. These worlds have moral laws, unbreakable ones. For example, in many MMORPGs, theft is simply against the laws of physics in that universe, as is murder but not dueling, much like in our universe traveling faster than the speed of light is forbidden. Why wasn't our universe designed with moral laws of some kind to protect one person from another (eg such a universe could allow dueling to the death, gambling, and adultery, but not murder, theft and rape, as part of the laws of physics). Free will and choice are not the answer, as I am not free to travel faster than the speed of light, regardless of my will or choice, nor is the ability to violate another's will necessarily and improvement in free will.
How would the world be different if someone else (eg the listener, or Mother Teresa) were made omnipotent and omniscient in place of God?
Nice questions. Could you please explain me how "Matthew 26:39" is related to "Jesus' willingness to die for our sins"?
I am about to graduate from one of the only universities in the world that has a high concentration of high-caliber analytic philosophers who are theists. (Specifically, the University of Notre Dame, IN) So as not to miss this once-in-a-lifetime opportunity, I have sent out emails asking many of them if they would like to meet and discuss their theism with me. Several of them have responded already in the affirmative; fingers crossed for the rest. I'm really looking forward to this because these people are really smart, and have spent a lot of time thinking about this, so I expect them to have interesting and insightful things to say.
Do you have suggestions for questions I could ask them? My main question will of course be "Why do you believe in God?" and variants thereof, but it would be nice if I could say e.g. "How do you avoid the problem of X which is a major argument against theism?"
Questions I've already thought of:
1-Why do you believe in God?
2-What are the main arguments in favor of theism, in your opinion?
3-What about the problem of evil? What about objective morality: how do you make sense of it, and if you don't, then how do you justify God?
4-What about divine hiddenness? Why doesn't God make himself more easily known to us? For example, he could regularly send angels to deliver philosophical proofs on stone tablets to doubters.
5-How do you explain God's necessary existence? What about the "problem of many Gods," i.e. why can't people say the same thing about a slightly different version of God?
6-In what sense is God the fundamental entity, the uncaused cause, etc.? How do you square this with God's seeming complexity? (he is intelligent, after all) If minds are in fact simple, then how is that supposed to work?
I welcome more articulate reformulations of the above, as well as completely new ideas.
