In the Old Testament, Israel thought that the best answer to all their problems was going to be what everyone else in their world had: a king. They were seeking autonomy from God in what they imagined would be a better way. For a moment, an earthly king may solve a problem or two, but their rule doesn't always lead to God. God's idea of a king is one who is in reckless pursuit of Him, being His representative to the people He leads.
