Gathered Community or Scattered Mission?

I have worked with parachurch groups such as Youth With A Mission and The Agape Force. These organizations and many more like them came into existence because of a perceived lack in local church ministry. Whether their emphasis is door-to-door evangelism, feeding the hungry, reaching the world's lost youth or building orphanages in war-torn lands... they all exist as a clear reminder that the average church in western culture is focused primarily inward. It is obviously important to "gather" the saints for such things as edification, exhortation, community and equipping for service. But... where are the "scattered" saints? How can we have more meaningful ministry outside the walls of the sanctuary? Should our main concern be how to get people into the building? What do we do with the millions of seeking folks who are so disillusioned with the church that they will not come inside its walls? How will we reach our post-modern culture? What might the church be missing here? Talk to me....
