Thus, idolatry is born out of childish impatience because of our disappointment with and lack of trust in the wisdom of God. God had liberated the Hebrew people from slavery in Egypt. God had led them through the wilderness, fed them, instructed them, made them a people. God brought them into the land of promise, a land flowing with milk and honey and delivered them from their enemies. We don't want to trust in you.
Faith is too hard.
We want a King like all the nations around us. Their Kings lead them and protect them and take care of all their problems. We want a King, and then we can be a strong nation like they are, maybe even a world-ruling empire some day. They asked Samuel to anoint a King of God's choosing. Samuel had been leading them as a prophet and judge, but without the absolute imperial authority of a King.
