Rene Padilla is one of the premier representatives of orthodox evangelicalism in Latin America. He has consistently championed integral mission, a holistic understanding of Christian mission in which there is no artificial barrier between evangelisation and social responsibility. Biblical, faithful to Scripture, contemporary and inspirational, the core message of this updated classic remains just as urgent as when it was first published twenty-five years ago (Eerdmans, 1985). This revised version includes a new essay on the contemporary history of integral mission, a history that began with the Latin American Theological Fellowship, progressed within the Lausanne Movement, is bearing fruit globally through the Micah Network, and challenges evangelicals to address the major issues of our day."
