a few quotes to savor - from a Chronicles of Narnia site - from the horse's mouth, as they say
"The audience grows to love Aslan and everything that he symbolizes; they begin to wish for someone like Aslan in this world. After finding this love for Aslan, they will ideally transfer that love to Christ when presented with the Gospel later in life. It is important to remember that The Chronicles of Narnia are successful because many readers do not realize the resemblance of Aslan to Jesus Christ."
"Although the readers may not notice the symbolism as a child, they will learn from the ethics of The Chronicles of Narnia, grow in character, and therefore be more accepting of the Gospel."
"In The Voyage of the Dawn Treader, the fifth book of the series, Aslan tells the children that although they must return to their own world, they can find him there also (Hooper 123). Aslan says, "There I have another name. You must learn to know me by that name. This was the very reason why you were brought to Narnia, that by knowing me here for a little, you may know me better there" (Hooper 123). Some of Lewis' readers wonder what the significance of this statement is and begin to search for Aslan here on earth."
