From Chris Wright's The Mission of God's People:
In addition to - and often to put us in a position to be - telling people about Jesus, we are to be a people committed to blessing others, walking in the way of the Lord, doing righteousness and justice, working for holistic redemptive blessing of the oppressed, and representing God by living lives of practical holiness in the midst of the world.
But at the bottom is this - something has to be seen by those beyond the limits of God's people. Invisibility is not much help in mission. It is not enough to be heard only; we must be seen as well.
