God has made us humans in God's own image. So therefore the highest way to talk about God is by some kind of analogy with ourselves. So, naturally, if we who are finite and sinful suffer in multiple ways because of sin and evil and the horrible things that happen in our world, how much more does God, who is infinite, sinless, and knows the totality of all that happens to everybody, suffer pain and heartache at the suffering of his human and non-human creation - and be angry at all that causes it?

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.

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.

Only the gospel exposes the cancer of idolatry.

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.

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

If "gospel" means good news, then Jeremiah had some for sure. He saw the judgment coming, in horrifying technicolour. But he saw beyond it to the redeeming, restoring grace of God, and indeed he speaks of the "new covenant", which takes us to the heart of the gospel in Christ.
