I just read this in My Utmost for His Highest by Oswald Chambers:
"The author who benefits you most is not the one who tells you something you did not know before, but the one who gives expression to the truth that has been dumbly struggling in you for utterance."
Bulls eye!
I've gotta read that again...
Yep, it hits the target of my own experience with the same precision each time I read it!
