The Magician's Nephew can be read as a great adventure, and it is likely that the adventure is what appeals most to its readers. An undercurrent to the adventure is kindness and mercy. After Digory brings evil into Asian's beautiful new world, he is given a chance to redeem himself, and in so doing, he brings peace and freedom from evil to Narnia. This is echoed in The Lion, the Witch and the Wardrobe, in which the traitor Edmund is redeemed by Asian's sacrifice.

Each case mirrors God's mercy and generosity, because in each case Asian (representing Christ) provides a way for people who have done evil to be forgiven and to have access to life beyond death.
