Most journeys are in quest of something.
Indiana Jones, Christopher Columbus, and Peter Pan are all in classic journey stories. A journey story basically features a character who wants something and overcomes obstacles to get it. We travel with them and intersect our imaginations with theirs. This is what makes journey stories interesting.
My friend Phil Ryken, President of Wheaton College, wrote a paper reflecting on the journey of Frodo in The Lord of the Rings. He was comparing it to the tri-fold ministry of Jesus as prophet, priest, and king.
