Here’s how the story was introduced:
In The King Without a Shadow, Dr. R.C. Sproul tells of a king who hears of another King — one so great He casts no shadow. The first king embarks on a search for the Great King, a search that leads to a bearded prophet called “The Man of the Cave.” “The Great King has no shadow because He has no darkness in Him,” says the prophet. “The King without a shadow is God Himself.”
This was a really beautiful story which teaches deep theological truths. I encourage you to listen to it and maybe buy the book or recording for a child’s Christmas present.
