My favorite quote about God was key to the lesson.
Lucy: Then is He safe?
Mr. Beaver: Safe! Who said anything about safe? Of course he isn't safe, but he's good.
In the book the analogy is used where theology (learning ABOUT God) is compared to a map of the ocean while the ocean itself represents God. You can study the map of the ocean and know it by heart, but until you actually encounter the ocean and set to sea upon it, you'll never really KNOW it. In the same way, while theology is not a bad thing, indeed it is a desired aspect of religion, it is our encounters with God himself that truly affect our relationship and our KNOWLEDGE of him.
This is why Aslan is so appealing as a representation of God/Christ. In this fictional character we are able to get a more "realistic" picture of what God might be like as he relates to us in our day-to-day existence. He is at once terrible and gentle, fierce and kind, stern and loving.
Aslan does not cater to the children's whims and desires for happiness and comfort. He expects them to complete difficult tasks and makes no apologies for doing so. He does not placate them by excusing their misdeeds. Rather, he accepts their apologies forthright, forgives them, and moves them on ahead still expecting nothing but their best efforts and total devotion. Their happiness is second to their long-term well-being. If going through struggles will ultimately serve them well, making them stronger, better, wiser, or more reliant on him, then so be it. This mirrors God's dealings with us.
It was a great class. I am now 2 chapters ahead in reading it and will probably have it finished before next week. I reccommended it before I'd actually read it...but now...I'm telling you firsthand....it's a GREAT book!
