This is a good illustration regarding Jer.10:23.
I well know O Jehovah, that to earthling man his way does not belong. It does not belong to man who is walking even to direct his step. - Jeremiah 10:23
A person asked, 'Does that mean merely that man was not given the right to rule?'
No. It means more than that. To illustrate ... Suppose you go out in the country and buy a cute little piglet, take him home with you, and do your level best to teach him how to fly. Show him films on birds flying, teach him how to flap his little legs, talk to him about aerodynamics, feed him bird food, and make him bunk in with the chickens for a month or two. Then take him up to the top of the barn and pitch him off with the command ... Fly,fly,fly little pig...
What will happen? Well it's obvious. He'll hit the ground like a brick. Why?? It does not belong to pigs to fly.
Moral of the story: When will man be able to govern himself?
Answer: When pigs fly!!!
