Perhaps I was too harsh on Tom Wright in my last post. He is entitled to interpret the "big picture" of the New Testament in any way he chooses.
However, I am searching for a good explanation of what Wright means when he says that Christians must be at work building the Kingdom of God. What does this look like, exactly. Is it political? Charitable? Because as soon as he tells us what the Kingdom of God looks like, we can fairly judge whether it is an exciting development or a bunch of twaddle. What does it have to show for itself after two thousand years?
As Joel hints at but takes in another direction, talk of Christ's victory over "principalities and powers" is senseless until you tell us what powers and principalities these are. Until then we might just have to conclude that you are obfuscating for fear of being exposed as holding an empty faith.
