The Mission is God's

Mission…in biblical terms, while it inescapably involves us in planning and action, is not primarily a matter of our activity or our initiative. Mission, from the point of view of our human endeavor, means the committed participation of God’s people in the purposes of God for the redemption of the whole creation. The mission is God’s. The marvel is that God invites us to join in.  ~ Christopher Wright, The Mission of God
