I like the Old Testament, or as we refer to it, The Testament. The leaders of the Israelites go to Samuel (1 Samuel 8) and tell him they want a king. Samuel doesn't like this, and God tells him to explain to the people what a king does. Samuel tells 'em: The king will take a portion of your wealth for himself, and he will reward this to his favorites. He will take your sons as soldiers and your daughters as servants.
Samuel tells this to the people but they tell him, "We want a king to be like the other nations and to fight our battles for us."
And that is what they get. Scripture tells us in no uncertain terms what a king will do, the people want a king anyway, they get a king, and then Scripture chronicles the 'good' and the 'bad' kings, and even the best of 'em do bad things.
King David commits some big sins, and goes down in Hebrew history like JFK at a later date.

I was young when I was taught this passage, and my personal take away was that God was a democrat.
