Founded in 1923 by William M. Strong, Sr. as a means of evangelizing the military in Chile, Gospel Mission of South America (GMSA) continues to enlist dedicated men and women who will go, pray and give to enlarge the work. Supplication, service and sacrifice are needed so that the message of redemption might be presented through the power of the Holy Spirit.

GMSA is a foreign missionary agency for the outreach of the Church in a missionary effort (Matthew 28:19-20). The Mission is baptistic in practice and cooperates with other organizations of like doctrine. It is composed of believers who unreservedly subscribe to its fundamental doctrinal statement and its Principles and Practice.We use three primary means to carry out our purpose statement and mission. The most important of these is the planting of local churches that are developed and graduated to national leadership. Another ministry that the mission does is Bible Institute training. This ministry makes use of gifted Bible teachers to train leaders for existing churches as well as for churches that are about to graduate and need national leadership. A third means that we use to carry out our mission is camp development. Christian camps serve as excellent places for evangelism, family spiritual development, church fellowship, and the like.

The mission is incorporated in the sending countries under the laws of Canada, the United Kingdom and the United States of America. It is also incorporated in its fields of service in Argentina, Chile, and Uruguay.

Terry Thompson is presently the general director of the mission and missionary Tom Gibbons is the associate general director.
