Its not entirely clear. But one thing is clear. And that is that those who belong to Jesus Christ in the present will actually, and I hesitate to say this because it sounds arrogant or triumphatalistic, but its what the new testament says, Those who belong to Jesus Christ will be running the new world, as Gods stewards. But take away all the sting of the idea of running things as being wicked bosses or forcing everybody to do this or that. Because the model of leadership and of ruling which is there, is that of Jesus himself. That of the gentle shepherd. That of the steward. Is that of the one who says, if anyone wants to be great they must be your servant. So, again and again, in Paul, in Revelation, and elsewhere, there is this sense that if you have learned in this life to look after the bit of the world that God has given you, which might be your own body, your family, might be business, a church, whatever. Then this is preparing you to help God look after his new creation. And thats awesome. I dont think Ive ever heard a sermon on that. But it is right there in the texts. And one of the loveliest lines of the text right at the end of the bible, it says, that out of the New Jerusalem, there flows a river and the river has trees on either side of it. And the leaves of the tree are for the healing of the nations. So there is a project of healing in Gods new world. What that means I really have very little idea. But it sounds full of hope and possibility.
