Perhaps preachers today need to think about the assumptions that are common in their congregation - the plausibilities and comforting assurances - which may in themselves have biblical truth, but can easily become insurance policies waved around as immunity from any kind of serious evaluation of how we are living, whether we are truly following the Lord Jesus in the way he walked, whether we are doing righteousness and justice as God commanded.

God cannot suffer - at least not as we do. It has some roots in Greek philosophy: if God is a perfect being, suffering would reduce that perfection, so God cannot suffer. More thoughtful theologians take the phrase in the sense of one of the confessions of faith that talks of God as being "without parts or passions" - he is not physical as we are, and not subject to "passions" in the sense of uncontrollable emotions that can take charge of us at times. God is not "emotional," if that word is used as some kind of weakness.

"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.

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 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.

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.

Mission means inviting all the peoples of the earth to hear the music of God's future and dance to it today.
