Guido: (learning how to be a waiter) How far do I bow? I suppose I can even go 180 degrees.
Eliseo: Think of a sunflower, they bow to the sun. But if you see some that are bowed too far down, it means they're dead. You're here serving, you're not a servant. Serving is the supreme art. God is the first of servants. God serves men, but he's not a servant to men.
-- from the movie, Life is Beautiful
God serves men, but He is not a servant to men. I reckon John Piper would agree with it. What do you think? Do you know how this is so?
