The missional church movement first arose during the end of the 20th century and the beginning of the 21st century. The movement seeks to rethink and redefine the nature of the church and create a new paradigm in which churches are seen as missional in nature, instead of attractional in nature. Leaders in the movement argue that instead of churches attempting to attract people to churches through church programs, churches should instead take the gospel outside of the church and engage society with the gospel, often by being involved not only in missions and evangelism but also in social justice movements. The missional church defines itself in terms of its mission — being "sent ones" who take the gospel to and incarnate the gospel within a specific cultural context. The church exists, in other words, for what we sometimes call "mission": to announce to the world that Jesus is its Lord.
