In 2008, Deseret Book released a talk where Wilcox examines Lewis' work and its relevance to Latter-day Saints. The following are lessons about Christ from "The Voyage of the Dawn Treader," abridged from the text provided by Wilcox for the CD, "Of Lions, Dragons and Turkish Delight."
Everything we read and learn and hear about (the lion), Aslan we are to apply and to think: "This is really the Savior that Lewis is teaching me about."
In "The Voyage of the Dawn Treader," the (natural man) is represented by a dragon. We are introduced to a young boy named Eustace. He's a very nasty little kid. He complains about everything. He's Lewis' symbol for all of us who need the change Christ offers.
