Were I just now attending my first conference it's hard to say how the experience would be; 430 people are a lot more daunting to an introvert than 90. Even knowing as many GCNers as I do now, I can only spend so much time in that large a crowd without needing to retreat for a while. All the same, I wouldn't miss it for the world.
Hopefully the day will come when the church as a whole has grown to the point that havens like GCN are no longer needed. That day seems to be a long way off, but there are more encouraging signs of change every year. The Body of Christ needs all of its members - perhaps especially the more "unseemly" ones. And wholeness is a dream worth pursuing.
