'The Great Commission is given to the church for this time between his first and second comings. It is an intermission between his accomplishment of redemption and his return to consumate its blessings. However, this intermission isn't a time for loitering in the lobby as consumers; it is a time of joyful activity on behalf of our neighbors: loving and serving them through our witness to Christ and also through our daily callings in the world.'
Michael Horton, The Gospel Commission, p.63.
