I give the credit to my friend, Tim Ellsworth, for writing this story. Before making any comments, please read Polly Toynbee's review as linked from Tim's site.
First, if you have ever debated with a devout atheist, it's like partaking in a fierce tug-o-war. No matter how convincing you are, the atheist refuses to see the 'unseen'. The only magic or mystery they believe in comes from a Harry Potter book.
Personally, I find this very sad. To the atheist, Mother Teresa was a myth or she was the exception to the norm. Sometimes as I observe the behavior of fellow Christians, I happen to agree somewhat with that last statement.
Second, devout atheists are very comfortable in their beliefs. They don't care if their soul goes to Hell for if they don't believe in it, why should it go there upon their judgement. And speaking of judgement, they could care far less for a sovereign and loving God who will condemn you for your disbelief in Him or his Son, Jesus Christ.
Third, acts of kindness or servitude to our fellows is trifle and intermittant. Says the atheist, "If one were truly a Christian, then why don't they act like one?" But the atheist view of a Christian is either a weak peasant or Rambo. There's no in-between.
As Ms. Toynbee seems to be an atheist, and quite a cozy one at that, so it's no wonder her sarcastic banter cuts so deeply into any Christian's take on The Chronicles of Narnia. She's a miserable person who could no more explain Aslan's resurrection (nor want to) as she could why the Chicago Cubs haven't won a World Series. Only Christ's sacrifice for our sins can be explained. The Cubs are a different story altogether.
I say all this for I have debated a few atheists since my conversion in 1999. And I must say, no matter the evidence from the mind or heart, they will stand their ground using some of the aforementioned tactics. It's only when a seed is planted, and God grows it, will the atheist come to the saving grace of Jesus Christ.
