This book contains the lectures from a 1892 course on foreign missions at the Theological Seminary of the Reformed Church in America, New Brunswick, New Jersey. The six lectures are: “The Holy Spirit’s Programme of Missions,” “The Holy Spirit’s Preparation in Missions,” “The Holy Spirit’s Administration in Missions,” “The Holy Spirit’s Fruits in Missions,” “The Holy Spirit’s Prophecies concerning Missions,” and “The Holy Spirit’s Present Help in Missions.”Adoniram Judson (A. J.) Gordon (1836–1895) came to prominence as the evangelical pastor of Clarendon Street Baptist Church in Boston. During his 25 years of tenure there, he saw a complete transformation of the church, with an unsurpassed effort in missions. A missionary training school and publishing house were associated with the church, and Gordon preached at many of D. L. Moody’s Northfield Conferences. His training school eventually became Gordon-Conwell Theological Seminary, in South Hamilton, Massachusetts. He also founded Gordon College, in Wenham, Massachusetts.
