Being evangelical in its doctrinal orientation, the Evangelical Churches Association strongly emphasize on the propagation of the gospel message of Jesus Christ. Thus, ECA started and support five mission fields, with the assistance of over local eighty missionaries who are either fully or partially sponsored by the church. The Lord has been mightily working among different people groups through this humble effort. The mission director co-ordinates all the activities of the missionaries from the ECA headquarters in Churachandpur.
