Book excerpt: Evangelical churches are widely known for their commitment to mission locally and to the ends of the earth. However, in the last century, there have been profound theological and sociological changes that have impacted mission practice. Church and mission leaders have encouraged Christians to respond to the need for mission locally, especially as church decline accelerates in much of the Western world. Yet others are concerned that global mission involvement is being neglected in many local churches. This study explores the factors influencing local church participation in mission both locally and around the world. Through an in-depth analysis of the practices and perspectives among evangelical churches in Australia, the author identifies a range of theological, missiological, and organizational influences on mission practice. Though beliefs about the church, the world, and mission are important, understanding organizational principles, social capital, and the power of relational networks provides invaluable insights into church-mission practice. This book is for those who long to see local churches committed to engaging both their neighbors and the nations in mission, growing our understanding of how to encourage helpful church practices for the sake of Christ.
