The scriptures are basically a narrative of God's interaction with human kind. If we lose this notion of God's desire for relationship with human beings, we're in danger of losing the heart of the Christian faith. Doctrines, of course, will flow from that, but when the scriptures call us to Believe, we're being called to put our trust in Someone, not just agree with a bunch of doctrine. Demons could do that. We are to commit ourselves to Christ.
