I just found this interesting article on Harry Potter’s magic, and thought I’d repost.
Although I do not think the author is a Christian, nor writing from that point of view, I think he brings up some good things to consider.
I especially liked his comparison of Rowling to Tolkien and Lewis. Very interesting analysis: I have said before that Tolkien is the master of fantasy, and Jacobs explains why very well.
Despite this essay being written before the completion of the series, I think the issues discussed therein are even more pertinent, now that the cycle is complete. Well worth a read.
