Externally Focused Church Leaders

I don’t recall who said it, but in a presentation at the Resurgence Conference, someone talked about External vs. Internal Church leaders. Who has examples of a group of leaders who are externally focused? At our church, most of the external leadership centers around our mecy ministries (homeless, teen mentoring, pregnancy crisis center, convalescent homes, etc.) Jamie Munson at Mars Hill serves on community boards and I know other churches have leadership get involved in these type of civic activity. I’d like to determine how to connect with business leaders in San Diego who have a passion for San Diego being redeemed.

What other types of external leaders should a church have? What would that look like? Should there be an equal amount of internal and external leadership in the church?
