Yahweh demanded justice for the poor, compassion and equality for foreigners and refugees, systemic redress for poverty, structural mechanisms to protect the homeless and family-less from abuse and destitution, fair and equitable distribution of land, integrity in the judicial system, humility, simplicity and morality in the government (as opposed to wealth, women and weapons), etc. etc. If you want that kind of society, you need to be faithful to the living God.

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.

"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.

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?

The issue in the Bible is not just "Do you believe in God or not?" Everybody believed in gods of some sort. The question was, "Who is truly the only living God?" And if that God is indeed Yahweh the God of Israel, then there are consequences in real life - as shown in the Torah.
