Recently I've decided to read through all the books of The Chronicles of Narnia in order, starting with The Magician’s Nephew, the story of Narnia’s creation. There’s a beautiful passage where Aslan the lion sings the world into existence:
"In the darkness something was happening at last. A voice had begun to sing. Sometimes it seemed to come from all directions at once. Its lower notes were deep enough to be the voice of the earth herself. There were no words. There was hardly even a tune. But it was, beyond comparison, the most beautiful noise Digory had ever heard. It was so beautiful he could hardly bear it. And then the blackness overhead, all at once, was blazing with stars."
And thus Narnia, in all its resplendent beauty, comes into being – a peaceful, flourishing, verdant land. But then, when you get to the second book, The Lion, The Witch and the Wardrobe, you discover that Narnia has been covered in perpetual winter (but there is never Christmas) and all the creatures live in terror and bondage. The White Witch has usurped the throne and reigns with cruelty and injustice.
In his stories C.S. Lewis deliberately echoes the story of the Bible, which says that the world was created beautiful and good, but that sin marred creation and brought a curse upon the land. This is why we continue to hear tragic news reports, such as what happened recently in Nigeria, when armed gunmen kidnapped over 300 girls to sell them into sex slavery. This world is full of pain and tragedy. We weep, but not without hope. For as said in the second Narnia book, "Aslan is on the move. The Witch's magic is weakening."
