The kingdom that Jesus preached and lived was all about a glorious, uproarious, absurd generosity.

God has committed himself, ever since creation, to working through his creatures--in particular, through his image-bearing human beings--but they have all let Him down.

There's all the difference in the world between humbly saying "I want to find more light from Scripture than we have yet had" and saying "I'm going to prove the rest of the Church wrong and do something totally new!"

It is a matter of glimpsing that in God's new creation, of which Jesus's resurrection is the start, all that was good in the original creation is reaffirmed. All that has corrupted and defaced it--including many things which are woven so tightly in to the fabric of the world as we know it that we can't imagine being without them--will be done away. Learning to live as a Christian is learning to live as a renewed human being, anticipating the eventual new creation in and with a world which is still longing and groaning for that final redemption.

For Paul 'righteousness' and 'justice' are the same word, as they were in Hebrew. Paul clearly believes that helping the poor is a central and ongoing part of Christian commitment, precisely because in Jesus Christ God has unveiled and launched his plan for the rescue, redemption and renewal of the whole creation. Justification and justice go very closely together.

God's plan is not to abandon this world, the world which he said was "very good." Rather, he intends to remake it. And when he does he will raise all his people to new bodily life to live in it. That is the promise of the Christian gospel.

Jesus himself, as the gospel story goes on to its dramatic conclusion, lives out the same message of the Sermon on the Mount: he is the light of the world, he is the salt of the earth, he loves his enemies and gives his life for them, he is lifted up on a hill so that the world can see.
