Inspiration - what is God’s word?

Josh and Paul tackle the far-reaching concept of inspiration.  What does it mean for something to be the inspired word of God?  Is it possible to explain how that happens, and if we can't, what certainty can we have about divine authority behind the text of the Bible?  As they consider these questions it becomes clear how important it is to treat the text with respect and be responsible and humble in how we draw out our interpretations.
