Why is there a battle?
When I read The Lion, the Witch and the Wardrobe as a child — and again when I watched the 2005 movie — I was deeply disturbed by the battle and its implications. Why does Aslan, the all-loving, all-powerful king of Narnia, stand up an army and make it fight a battle against the white witch’s army?
If he needs an army in order to accomplish his will, then he is not all-powerful. If he doesn’t need the army, then he is sending four children and countless Narnian creatures into combat unnecessarily. My thanks to C.S. Lewis for this handy illustration of the problem of evil.
