NT Wright is probably the leading New Testament scholar of our generation. He's certainly the most prolific. After examining the Ressurection of Jesus here's what he concludes is central to the church's mission:
Thus the church that takes sacred space seriously not as a retreat from the world but as a bridgehead into it will go straight from worshipping in the sanctuary to debating in the council chamber— discussing matters of town planning, of harmonizing and humanizing beauty in architecture, in green spaces, in road traffic schemes, and (not least in the rural areas, which are every bit as needy) in environmental work, creative and healthy farming methods, and proper use of resources.
If it is true, as I have argued, that the whole world is now God’s holy land, we must not rest as long as that land is spoiled and defaced.
This is not an extra to the church’s mission. It is central.
Politics, town planning, architecture, green spaces, traffic flow, environmental work, farming methods, proper use of resources? Really. Central? This is what Jesus did? This is why he died and rose again? This is what he sent his disciples into the world to do?
Turn the fruit of the gospel into the gospel itself, and we lose the gospel.
What did Jesus do? What did he train the disciples to do? What does the risen Lord continue to do in the Book of Acts? Keep that central.
