How Much Would You Give to Know Your Bible?

"An enthusiastic young man once introduced himself to a well-known Bible teacher with the words, 'Oh, Sir, I'd give the world if I knew the Bible like you do.' The older man looked him straight in the eye and replied, 'Good, because that is what it will cost you.'" (Referenced from the new autobiography, John MacArthur: Servant of the Word and Flock, pg. 17).
