Most Christians know and understand that we are to seek to reach the lost around the world. Yet, Christ's command to us is more specific and calls us to a higher standard of involvement with the peoples of the world. He has called the church to make disciples of all people groups and to teach them to observe all He commanded us (Matthew 28:18-20). In recent years mission agencies and missionaries have increasingly shifted away from discipleship and teaching toward an emphasis upon evangelism and church planting—many to the exclusion of any other field activity. While evangelism and church planting are essential components of a biblical missions program, they are not sufficient for the complete task to which we have been called. Reaching and Teaching examines the task Christ gave in the Great Commission and redefines the task of missions from that which is currently prevalent. It surveys missions strategies and methodologies that have increasingly replaced Christ's Great Commission instructions even as they have sought to fulfill it. It is a clarion call to return to the biblical task of reaching and teaching the nations for Christ's sake.
