This book is about a vision. A vision about Jerusalem. God was mad because his children had rebelled. The children offered sacrifices but God was so angry he refused it. God states that their incense is detestable, and when they pray to Him, He hides his eyes.
“Your hands are full of blood!” God says to his children.
Man expects peace and prosperity. God is angry at man’s arrogance. God says that man will abandon his idols and run to the caves in fear of God’s vengeance.
Mankind will be ruled by children. Mankind is proud of their sin.
Women behave disgracefully. God will cleanse the bad and protect the good.
Vineyard analogy. Did everything right but only bad grapes grew. “And he looked for justice, but saw bloodshed; for righteousness, but heard cries of distress.” See 5:20-22
It sounds like God is accusing mankind in his instructions:
9 He said, “Go and tell this people: ” ‘Be ever hearing, but never understanding; be ever seeing, but never perceiving.’
10 Make the heart of this people calloused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.”
