In the Bible and some books, allegory is used to illustrate a spiritual truth or generalization. When I was a child, I read a very entertaining series of books by C.S. Lewis titled "The Tales of Narnia." Every book in the series involved a journey, a quest or battle to overcome, and the main characters were always united in the "highlands" (Heaven). The main characters were children and a lion named Aslan, who was the king of Narnia. Aslan was a representation of God and of course the children were a depiction of the children of God. When I read the Tales of Narnia as a child it was obvious to me that there was a spiritual meaning behind the story. As an adult I realize The Tales of Narnia are an allegory of the soul's journey toward's God.
