In recent decades, many people have begun following Christ while remaining a part of their non-Christian religious communities. These "insider" Muslim, Hindu, Buddhist, Native American, and other followers of Christ have generated much interest and controversy, particularly in Western mission agencies and churches. In this book Duerksen analyzes the ways in which God's Spirit may be creating "alternative missiological imaginaries" through these individuals and groups, and how their understandings of and witness to Christ can challenge, expand, and de-center prevalent Western understandings of Christian mission and discipleship.
