First, as far as "incest". Remember, mankind was PERFECT when God made us. So when Adam and Eve sinned, their bodies first started to break down. Thats why they lived for hundreds of years, there wasn't the disease or imperfections that have come over time. Thus, there was not the gross imperfections that you see now in incestuous relationships.
Think about this for a second. We are copies of copies of copies, and so on, for thousands of years. Yet we still are living, breathing creatures.
Try taking a piece of paper that you typed, take it to a copy machine, and make a copy. Then use the copy and copy it, Keep doing that and see how few times it takes before you can't even READ the print. Yet look at how man is still here.
Zero, the Bible was inspired by God. It says in the Bible that anyone that changes it's meaning will be held responsible for doing that. All you can do is trust Him, and let Him worry about the results.
Dcube.....look at the things you wrote, then ask yourself this question: If mankind would have obeyed what God said in all those, what you called "immoral" passeges in the Bible, would we be better off today?
Would we have the moral decay, and the results with disease if man would have obeyed God? Gay sex, sex before marriage, .....how many people have died from sexually transmitted diseases? These would have been avoided if men and women learned some self control.
How about adultry? You think it's wrong for God to expect people that make a VOW before Him to ONLY have sex with their mate, to hold them to that?
God put down some laws, that IF they were obeyed, mankind would flourish.
But like in today's world, people want to do WHATEVER they want, with no consequences.
Fact is, there ARE consequences to everything you do.
As far as the Bible contradicting itself, it doesn't. You can take verses out of context, and they might look contradictive. But if you compare it with other scripture, you see that it doesn't contradict at all.
God doesn't want evil to happen to people. But Satan does. And lets face it, alot of what happens to us is our own fault, because of choices we make.
Too many people want to blame God for that.
If you choose not to believe the Bible, you will take things like His judgement for OUR actions as Him being cruel. Of course thats because we don't want to take any guilt for what we do.
"If it feels good, do it" has been man's way for a LONG time.
