Movements—such as Luke documented in the book of Acts—are the primary means by which gospel impact outpaces population growth. When God’s Spirit moves, such movements rapidly sweep many households into receiving God’s blessing in Jesus Christ, transforming their communities and their people group.
The essential seed for Jesus movements is a contagious community of believing households within a given people group. Where this seed is not present and growing, people groups tend to believe that Jesus is only for Christians, and to drive those who follow Jesus from their midst. However as believing households witness to and multiply the blessing of God in Jesus, the perspective of a people group can shift to recognizing Jesus as the savior of the whole world, including their own people (John 4:42)!
