I recently sent a copy of N. T. Wright’s The Challenge of Easter out to my Grandma Ocie. She reminded me of this passage in which Wright sets out the challenge that we Christians must take up today:
We live in a time of cultural crisis. At the moment I don’t hear anyone pointing a way forward out of the postmodern morass; some people are still trying to put up the shutters and live in the premodern world, many are clinging to modernism for all their worth, and many are deciding that living off the pickings of the garbage heap of post-modernity is the best option on offer. But we can do better than that. … The gospel of Jesus points us and indeed urges us to be at the leading edge of the whole culture, articulating in story and music and art and philosophy and education and poetry and politics and theology and even, heaven help us, biblical studies, a worldview that will mount the historically rooted Christian challenge to both modernity and postmodernity, leading the way into the postpost-modern world with joy and humor and gentleness and good judgement and true wisdom.
I believe we face the question: If not now, then when? And if we are grasped by this vision, we may also hear the question: If not us, then who? And if the gospel of Jesus is not the key to this task, then what is? — N. T. Wright 
We must not forget that we have the right message, but we must also remember “joy and humor and gentleness and good judgment and true wisdom.”
