See part 1 in the series of quotes from Total Church:

“Missions begins in our own hearts as the gospel word of Christ crucified is effectively applied by the Spirit. And it does not stop until the far corners of the world. It is a constant continuum because mission is what we might call the steady state of God’s people. The early church understood mission very well. Vinoth Ramachandra, the IFES Secretary for Dialogue and Social Engagement in Asia, says, “Missionary outreach, both to Jews and to pagans, was not an activity tagged on later to a faith that was basically ‘about’ something else; rather it flowed from the very logic of the death and resurrection of Jesus”.
