If Jehovah/Yahweh is the creator of all things and the Most High, how on earth, or in heaven come to that could his Sovereignty ever be challenged? Didn't Paul say something about the potter and ask can the thing made say to the potter why did you make me?
The ability to procreate doesn't make one a good parent.
The ability to create humans, doesn't make one a good ruler.
God proved his power, Satan just want's him to prove his right to use that power. Otherwise Jehovah is just a bully, or an abusive parent.
What about the Flood? Surely the issue, if there was one, must have been settled back in Noah's day otherwise God would not have destroyed mankind back then would he?
That incident strikes me as similar to a five year old overturning the board as he is about to lose.
The tower of Bable strikes me as similar to a four year old changing the rules mid-game.
Making humans imperfect stikes me as similar to a parent cutting off their childs arms and legs and throwing them in a ditch and saying: "So you think you're better off without me huh?" - "WELL NOT LIKE THIS, NO!"
I'd like to see Satan's challenge actually answered. How well would perfect humans rule themselves?
