Gene Vieth in his Book “The Soul of The Lion, The Witch and The Wardrobe” brings up an interesting point here. He says that after Edmund leaves the Beaver’s house, Lewis begins writing from Edmunds point of view and that forces us see things from Edmunds point of view. It reminds us we have done things similar to what Edmund has been doing without the amplification of the fantasy framework.
The same thing that Aslan offers for Edmund alone, God offers every human being who has ever lived on planet earth. But there is a cost.
