God is inviting His people into a new way of being His Church. He has been for some time, frankly.
In a mostly Christian society, the Church could focus on being attractional... offering the best programs and ministries money could buy in an attempt to be the center of community life. Success was measured in terms of the ABCs (attendance, buildings, cash).
Now in American society, most people don't go to church; they don't really want to, either. And so, just like in the apostolic age... the Church will go to them, incarnationally embodying and sharing Jesus through real relationships at work, at home, and at school. Success, here, is measured in stories... of lives changed, and relationships transformed, by the very power of God.
This excellent 2-minute video sums up the difference quite nicely.
