This can be helpful. It keeps our presentation short, focussed and direct. However, while the ideas themselves may be simple enough to explain, they become divorced from the story, and so they fail to give a clear overall picture. If we present the gospel as it comes to us, as a big story, it takes longer and there is more information for people to digest. But there is something about a story as a means of communicating.
People love stories.
We find it difficult to put them down. Stories engage our emotions. We are drawn in as we see the various elements develop and we move with then toward the climax. The People of God Course tells God's story. It moves from life of God intended in the creation, to life as we experience it due to the Fall.
