“There are two kinds of pastors:
Those who are upset the church isn’t going to the lost
Those who are upset the lost aren’t coming to church.”
I like the quote because it captures the difference between incarnational evangelism and attractional evangelism. Mike Frost is one of the most articulate spokesmen for incarnational evangelism. And Tim Keller also speaks around these concepts in his brief but excellent The Missional Church (pdf).
I personally believe that both approaches can be appropriate in certain contexts.
