The groaning of the Church
I haven’t read N.T. Wright, but I came across a short interview with him in Newsweek (http://www.newsweek.com/id/134306) which offers a nice explanation for all the disagreement among Christians (and people in general).
He cites the notion that ‘the creation is groaning, having been subjected to slavery’ from Romans, and says that the Church is also ‘groaning’ in this sense. There’s a subjection to fallen-ness that affects us all and leads to these internal and external squabbles.
I guess this is just a way of saying our problems are because of sin, but in all this ‘groaning,’ it’s helpful to me to be able to locate it in the story of redemption.
