Believe me, I take it very seriously. The entirity of the Bible is inerrant, inspired by a perfect God incapable of lying. In it's original form, there can be no flaw in God's word.
What I don't trust is the manner in which people interpret God's word. Not everyone can be right. And a whole lot about Genesis is opinion. People can and will argue endlessly about particular issues, but I'm going to put my trust in God, not the earthly reasonings of philosophers, creationists or atheists.
God wrote the Bible the way he did for his reasons. He could easily have made it plain and simple by making it completely harmonious with science, but that wouldn't have done for 2000 yrs ago. It's written the way it is, and it still amazes me that when I come across things that worry me there's always a good explanation for the problems. And for every tiny little issue that crops up, the Bible has a thousand incredible and mindblowing statements that have held true for 2 millennia of humanity.
So, since that's all about as clear as mud:
I believe:
1) The bible is inerrant
2) The bible will agree with true science, because God does not lie and would not create a mendacious universe.
3) Apparent contradictions can be removed by close study of original context and language
4) Finally, and most importantly, all this discourse is irrelevant, because my God doesn't need a book to talk to me and guide my life. I became a Christian without taking the Bible all that seriously. It's wonderful how incredibly important it becomes over time, but it's a secondary issue. God himself is the most important thing for me.
So, at what point do I start worrying about how to interpret the Bible? When it gets to stuff that directly affects my life. How to act, what to do, what Jesus did for me and what I need to give in return. There's few arguments over these, because they're what really matter. And it's amazing how focused God gets about stuff we need for truly knowing him and inheriting his kingdom.
God Bless,
