God Names the Stars (Psalm 147:4-5)

It's not like He needs to call them to supper or remind them that it's time to hurry up and get ready.  He won't be singing them a silly song or tucking them into bed at night.  I can't imagine he'd holler from afar when they're about to do something dangerous.  He doesn't need to call one, and differentiate it from the others.  It's not even like he needs to whisper in their ear, convincing them of His love.  Why do you think God names the stars?
