What is the primary role of missionaries within christian faiths?

Many people picture a missionary as a middle-aged man who leaves his job in America to evangelize and plant churches in Africa. But that is a simplistic view. Today, African Christians reach out to Muslims in the Middle East. College students spend their summer teaching English in Asia. A family in America befriends and witnesses to international students. A truck driver responds to an international disaster, meeting both physical and spiritual needs. All these are missionaries.

Although missionaries cannot be stereotyped, they each have a call. God calls them to set aside personal ambitions in order to be witnesses of the Gospel. Like Isaiah, a missionary gladly responds, "Here am I. Send me!" (Isaiah 6:8b). Often God sends a missionary to a particular people group as Paul was sent to the unreached Gentiles and Peter to the Jews (Galatians 2:8). Although technically a Christian missionary is one specifically called by God and sent out by the local church, every Christian has a mission to make disciples. 

 A Christian missionary proclaims Jesus as Savior and Lord. Whom do they tell? Jesus made it clear that Christians are to reach out to “all the nations” (Matthew 28:19), especially those ethnic groups without a Gospel witness. Unreached people groups are still waiting for the way, truth, and life found in Christ (Romans 15:20). But Christians at home should be missionaries in their own communities, doing personal evangelism (Acts 1:8).

Missionaries do more than evangelism. The commission was to make disciples, not immature believers. Thus, a Christian missionary’s outreach involves evangelism, discipleship, and church planting. These main goals are accomplished in a variety of ways: street preaching, tract hand-outs, church building, Bible studies, teaching English as a second language, relief projects, children’s clubs, mountain trekking, literacy teaching, radio broadcasting, etc.
