A lot of people would like to see the church grow through the work of the Holy Spirit. In the book of Acts, however, it is Spirit of prophecy that is the leading edge of the mission of the apostles, and there’s a reason for that. In times of disruption and disorientation, the church needs to know what story it is part of—where we have come from, where we are going. The Spirit of prophecy, poured out on the community of disciples on the day of Pentecost, plots a way through the crisis.
