Jeremiah was given a difficult task, and the problem was nobody listened. God brings a case against his people: they had turned their backs on him, and turned to idols. The attraction was strong and took them to some dark places. You may not always understand God, but you can always trust God. In Habakkuk God tells him he is doing something he won’t understand, he is bringing his salvation out of injustice, his peace out of violence. In other words salvation is coming out of judgment, Light is coming out of darkness.
