Opening The Chronicles of Narnia to get lost in Aslan’s country is as easy, joyous, inviting, and stunning thing to do, as climbing into a warm bed for comfort and rest. Lewis’ work throughout these seven volumes is indeed legendary, and I’m sure, will be around for many centuries. Though we did not cover all of it and though it is true that we have seen some parts of it that are very hurtful to the reader, I do submit that any reader will be helped a great deal by reading these fiction stories. The series is indeed a pre-baptism of Christianity, and it should be taken as nothing more. If it is taken as a full orbed systematic theology from Lewis or something along those lines, disappointment will surely follow quickly. It is clear that Lewis could have done a far better job in certain places portraying Christian doctrine, but even after all these mistakes cleared up, Lewis is not inspired, only the Bible is. If the series is taken as what it was meant to be, a children’s fiction fantasy world, no reader will be upset. Though it is still true, the ideas within this fantasy world have their consequences that need to be talked through.
Overall the most fascinating thing about the whole mythology is of course, the character of Aslan. The picture Lewis paints in Aslan shows the world what God in Jesus is like to humanity. This stunning picture of glory and grace put into detail over and over throughout the mythology takes my breath away every time I open it to behold. Is God really as gracious, powerful, terrible, beautiful and lovely as Aslan is? No, He’s better! When Christians get to heaven and behold the Lamb of God on His throne, Aslan will look like a pot-hole in comparison to Lord of Glory!
Mr. and Mrs. Beaver said it well in The Lion, The Witch, and the Wardrobe, “‘Safe?’” said Mr. Beaver; ‘don’t you hear what Mrs. Beaver tells you? Who said anything about safe? Course he (Aslan) isn’t safe. But he’s good. He’s the King, I tell you.’” 
Narnia represents everything that is most hateful about religion…of all the elements of Christianity, the most repugnant is the notion of the Christ who took sins upon himself and sacrificed his body in agony to save our souls…Did we ask him to?
No, we didn’t ask Jesus to do this. I don’t think we would have given the option either. He chose to do so. He willingly died to bring us to God.
“Christ died for sins once for all, the righteous for the unrighteous, to bring us to God.” (1 Peter 3:18)
 Lewis, 146.
