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?

It's important, though, that there are not "four gospels." There is only one gospel: the good news of what God has done through Christ to save the world. But we read that one gospel in four complementary accounts: The gospel, according to Matthew, according to Mark, according to Luke, according to John.

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.

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

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.

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.

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.
