Book excerpt: How should we bear witness to the gospel in a postmodern world? How do we navigate the turbulent waters of social, cultural, and religious difference in a pluralistic society? How can we minister effectively in multicultural contexts and swim against the unconscious currents of ethnocentrism? These questions compel the church to thoroughly reconsider its priorities and rethink its strategy of public engagement. Amidst the diversity and the complexity of our world, such an examination can rekindle our prophetic imagination and equip us ever more fully in God's kingdom purposes. This book reexamines the church's mission and makes specific applications in numerous areas of contemporary concern, including outreach to the religious unaffiliated, digital natives, people of other faiths, immigrants, and the poor.
