Here's a question that might be a good way to "get to the point" when discussing religion. Supposing it's possible that one day you and God disagree on something, what do you do? Do you do what God thinks is right, or do you do what you think is right?
Christians sometimes seem more afraid of not being called Christian than they are of not doing the right thing. Jesus cared more about the spirit of the law than the letter of the law, even though he also said that not even a tilda would be erased from the law of God (interpret this however you want). Nonetheless, if it is the spirit of the law that matters most, then it does not matter whether we are Christians or atheists, it only matters if we live with love and careful regard towards all those whom our actions affect. So I'd ask you: how do you answer?
