I'm pretty sure you won't think this is an acceptable answer, Vivacia, but I'm going to post it anyway, since it's what I think and it's in line with the mainstream of Christian belief.
The Bible isn't one book, it's a library of different books written over a long period of time. Some of it is poetry, some of it is prayers, some of it is what is known as wisdom literature, some of it is prophetic writings, some of it is biography, some of it is letters, some of it is histories.
We read all these genres in different ways. They all have different things to tell us about the evolving relationship between God and humankind.
If by 'believe' you mean 'take literally without any consideration of context ', well no, I can't say that I do believe the whole of the Bible.
But since that's not what I mean, by believe that's not a problem for me. I believe that the Bible is the record of God speaking to and through imperfect human beings, and that it is full of truth and wisdom and mystery and beauty and horror. And I believe that we need to read it in an intelligent and informed way, not little bits but the whole of it,. I believe it's a well that always has water, and a candle that will always shed light. And I believe that to approach it reverently is to approach it with knowledge and understanding.
