How big is our gospel? If our gospel is the good news about God’s redemption, then the question moves on to, How big is our understanding of redemption? Mission clearly has to do with the redemptive wok of God and our participation in making it known and leading people into the experience of it….The scope of our mission must reflect the scope of God’s mission, which in turn will match the scale of God’s redemptive work.
