This question is for everyone, atheist, anti-theist, and believers alike. Suppose one evening God said to you, "Come and have dinner with me and I'll answer any questions you have." What would you ask him? Would being with him be enough?
For me, I'd have to ask why there are so many interpretations of the Bible, and how Christians can be expected to 'sort the wheat from the chaff' as it were. I'd also have to ask why Jesus killed the fig tree, because that is a downright perplexing bit of the Bible. Finally (probably at the end of a long list of questions) I'd ask him what exactly he thinks Christians have to offer atheists, given that both sides can be kind, caring, and loving. Other than that, I'd be glad that, in my case, the debate was finally settled as to whether God exists or not.
