The Bible itself does not seem too bothered by the idea that talking of God suffering might in any way diminish God, or detract from his perfection. On the contrary, the Bible seems to revel in the richness of describing God in ways that reflect our own human realities.

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.

"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.

As Paul says, even though we as human beings know God, we refuse to acknowledge him. That's what Peter did. He refused even to "know" Jesus! Peter's failure reflects all our failure. It forces us to face the reality about ourselves. But the point of the story is that Jesus foretold this - he knew it was coming. And Jesus forgave Peter, when Peter confessed his love for Jesus. So the story illustrates both the horrible nature of sin, and the amazing reality of grace. That's essential to the whole meaning of the gospel.

Only the gospel exposes the cancer of idolatry.

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.

The Bible itself does not seem too bothered by the idea that talking of God suffering might in any way diminish God, or detract from his perfection. On the contrary, the Bible seems to revel in the richness of describing God in ways that reflect our own human realities.
