Here is an hour-long panel discussion at The Gospel Coalition with Matt Chandler, Kevin DeYoung, Jonathan Leeman, and Trevin Wax on the the Great Commission and the mission of the local church.
Far and away the best thing I have read on these issues is the forthcoming book by Kevin DeYoung and Greg Gilbert, What Is the Mission of the Church? Making Sense of Social Justice, Shalom, and the Great Commission (forthcoming from Crossway in September).
Here is a blurb from Matt Chandler about the book:
In what appears to be a growing tension over what the mission of the church encompasses, DeYoung and Gilbert bring a remarkably balanced book that can correct, restore, and help—regardless of which way you lean or land on all things “missional.” I found the chapters on “social justice” and our motivation in good works to be especially helpful. Whether you are actively engaging the people around you with the Gospel and serving the least of these, or are hesitant of anything “missional,” this book can help you rest in God plan to reconcile all things to himself in Christ.
