Timothy Beal said this quote

The history of the Bible is one of perpetual revolution. In that light, we might begin to think about the Bible not so much as a fixed thing but as a dynamic, vital tradition. In light of its history, the Bible looks less like a rock than a river, continually flowing and changing, widening and narrowing, as it moves downstream. For some, thinking about the Bible as a river and not a rock is liberating. That rock has been a millstone around the neck and a tombstone that won’t be rolled away. But for others, seeing it this way can be disorienting. That rock has promised solid foundation in a stormy world. Cling to it or be swept away.
