I had a fabulous time at Together for the Gospel this year.  But, as I've already stated, I thought, as much as I love him and his ministry, that Mark Dever went too far, almost making any kind of civic involvement or cultural engagement a waste of time.  This helpful article in Christianity Today by Colin Hansen expresses what I was thinking.  People like Wright go too far one way, while, at least I think, Dever goes too far the other.  Again, I think Keller is balanced and right on.
