It's actually been well noticed that there are very symbolic references and parallelism between Narnia and the Bible. Here are a few:
The White Witch- The White Witch parallels the Devil in many places in this book. She is the unrightful ruler of Narnia, though Aslan is the one who created it.
Aslan- Aslan, obviously, parallels God like you noticed.
The Stone Table- The Stone Table parallels the Cross
The Statues In The Witches Palace- I believe that when Aslan, Susan, and Lucy came and turned the statues back to living creatures that it paralleled when Jesus, after his death on the Cross, went down to Paradise.
When Aslan Feeds The Army- In the book, Aslan's army, after they had defeated the Witch, were fed by Aslan himself. The Pevensie's said they never knew where he got all the food for them to eat. This parallels when Jesus fed the 5,000.
Wiping off of blood on Peter's sword- When Peter wipes the blood of of his sword, this may parallel the fact that we need to "wipe" off our sins by asking for forgiveness. Aslan said to Peter to ALWAYS wipe the blood off of his sword, like we need to always repent of our sins after we have committed them.
Do you think you also agree with some of these...?
Hope this helps!
Best of Luck!! ( ;
