What is so striking in the book of Jeremiah is how many times it is impossible to distinguish between the words of Jeremiah and the words of God, when deep feelings are being expressed. That is probably intentional. The prophet not only speaks what God says, he also feels what God feels. The tears of the prophet are the tears of God.

"It is finished" means that Jesus had accomplished all that God's mission had sent him to do. It did not merely mean that his life was over like, "I'm finished". It was a statement of achievement of purpose - God's purpose to deal with sin and guilt, to defeat all the powers of evil, to bring about the reconciliation of enemies, to defeat death itself, and to accomplish the reconciliation and liberation of the whole creation.

The Jews believed they were the nation God had chosen among all the nations. And they were. But that did not give them immunity to God's judgment. Like the nations, they too would feel God's wrath if they refused to live in God's ways. Furthermore, God could deal with other nations in mercy as well as judgment. Jeremiah was full of surprises, as against the popular religious assumptions of his day. That's perhaps why some people, when they encountered Jesus, thought he was very like Jeremiah. He turned things upside down.

The church was made for mission-God's mission

We may legitimately see in the [Old Testament] event, or in the record of it, additional levels of significance in the light of the end of the story – i.e. in the light of Christ

Old Testament Israel had some foundational pillars of faith. They were true and robust and God given. The trouble was that people had come to trust in them merely by repeating them, without paying any attention to the ethical implications of what their faith should mean in how they lived. They believed God had given them their land. He had. But they had not lived in it in either gratitude or obedience. They had not fulfilled any of the conditions that Deuteronomy had made so clear.

We tend to speak of sin in very personal and individual terms. Jeremiah does not downplay that, but he also sees how a whole society can be bound up in the tentacles of sin, in the assumptions that everybody around you makes, about how it becomes easier to sin than not to, and how we can become so confused and contradictory in our reactions, when sin is pointed out.
