4) because there's no proof the bible is truth and that can be disproved as there are plenty of contradictions in the bible. Anyone who believes in it has no good reason for it other then a personal experience or being brought up in the religion.
87. When Christians tell you that The Bible is inerrant you go on and list a bunch of "contradictions"; when the Christian shows to you that those are not contradictions but the result of taking things out of context you list more "contradictions" when the Christian does the same with those you complain that he/she is just making stuff up and/or that the answer the Christian gives you are not "satisfactory" and proceed of course to list more "contradictions".
89. You like to list contradictions to Christians like if you some how pretend that Christians are not aware of them or that they are igorant about their own religion.
217. When a Christian's interpretation of a passage (based on the social/literary context) solves one of your favorite contradictions, it is only their personal interpretation, and can be dismissed as such. But your interpretation (based on a "plain" reading of the text) to arrive at the contradiction in the first place is entirely objective, and is obviously THE correct interpretation.
6) that actually isn't what grey said at all. He's giving reasons that he doesn't believe in it and so far has countered most your points on why you believe in it and you have not done the same. This is not about: "i don't believe in it and that's why you shouldn't either", this is about "i don't believe in it, what good reasons do you have to believe in it?".
10. You consistently deny the existence of God because you personally have never seen him but you reject out of hand personal testimony from theists who claim to have experienced God as a reality in their lives.
26. You believe in many things about history (the culture of the ancient Mayans, egyptians, etc.), yet you refuse to accept personal modern-day testimony from someone who has personally experienced God.
You've been given plenty of reasons by every Christian you asked why they believe, and you just plug your ears and say "it's not good enough for me." Guess what, it's not my job to convince someone who doesn't want to be convinced.
