Four different nations harrassed Judah. When Hezikiah became king, the nation began a slow road to recovery and economic strength. Hezikiah probably heeded much of Micah advice. This was God's discipline upon the people, actually showing how much he cared for them. Choosing to live a life apart from God is making a commitment to sin.
Sin leads to judgement and death.
God alone shows us the way to eternal peace. His discipline often keeps us on the right path. Judah's transgression Emphesis vs 7,8 Idols other than God. Wages gathered by using prostitues. Maybe you better listening to the one who will keep you drunk.
