Jesus is calling his church to be a multiethnic and missional people who listen and learn from the many voices of world Christianity. Graham Joseph Hill issues a moving call for churches to be missional by being conformed to the image of Jesus Christ. Hill does this by exploring the thinking of twenty-five Asian, African, Latin American, Indigenous, African American, diaspora, Caribbean, Oceanian, Eastern European, and Middle Eastern pastors and theologians. These are as diverse as Melba Padilla Maggay, Emmanuel Katongole, Lamin Sanneh, Oscar Muriu, Ruth Padilla DeBorst, Pope Francis, Richard Twiss, Lisa Sharon Harper, Willie James Jennings, Ada Maria Isasi-Diaz, Soong-Chan Rah, and Mitri Raheb. These voices show us the future of missional churches in world Christianity. When churches are conformed to Christ they make disciples, heal a broken world, and witness to Jesus and his gospel. Jesus forms us in his image and moves us to be a people of shalom, humility, character, justice, peace, wisdom, prayer, beauty, and witness. The church has had a Reformation but now it needs a Conformation. Hill explores biblical themes and the voices of world Christianity to show that a missional church is conformed to the image of the incarnate, crucified, resurrected, and glorified Christ. Conformity to Christ is the heart of missional ecclesiology and discipleship.
