Christians say that the Bible is inspired by God. It is a concept drawn directly from Scripture, but what exactly does it mean? It is one of the more subtle questions of theology, but also one of the most important.
There are a number of different viewpoints on exactly how inspiration plays out. I personally believe it means that God chose every word of the text of Scripture. He literally wrote the words of the Bible through the human authors.
But then again, that is why it is hard for us to figure out. There were human authors. Individuals who wrote things, probably not thinking they were particularly special at the time. These individuals have a multitude of ways in which their personalities and style comes through in the portions of Scripture they wrote.
But does that mean, God is out of the picture? I don’t think so. Assuming the variety of human voices in Scripture, excludes God, is equivalent to assuming God is very small. God who created each one of those human beings instilled into them their unique traits. Why would we believe God is big enough to create all those different persons, but not big enough to use and speak through each one uniquely?
