The people rebelled out of arrogance when God gave them everything, so He tried to punish them. They still did not listen, so He made it worse and worse. Nothing worked, they still turned away. God sarcastically tells them to go ahead and worship their idols, but warns of the inevitable consequences. The prophets ends by beseeching the people, please prepare ypourselves to meet God. The way you treat Him, will be the way He treats you.
