From 'Missional Church and Church Planting' by The Porterbrook Network:
As the people of God...we are to be a gloriously transformed community. We are a 'third culture' - neither Jew nor Gentile but the people of God. Under the new King, Jesus, we are to lead lives that are radically different from our surrounding culture, because our lives are being transformed by him. Under God, we seek the good of the city, loving those who are unloved in the city, reaching out and gathering people in, attracting people by the quality of our lives. That is how we have a glorious impact on the nation.
Can you think of ways that your community group is providing a 'third culture' as a concrete demonstration of God's kingdom? How else might you offer your neighbors the opportunity to taste and see that God's rule is good?
