The GCM Collective website just launched as of this past Monday. Already there has been some outstanding ongoing discussion within the groups. I have personally found the conversation both thought provoking and helpfully. Well worth a look.

This from the GCM Collective website:

It is a gospel community that lives out the mission of God together, as family, in a specific area and to a particular people group by declaring and demonstrating the gospel in tangible forms. God is moving to create thousands of new gospel communities on mission around the world. Be a part of this movement.
