Like the vast majority of our American Presbyterian forefathers and foremothers, the life and ministry of John Leighton Wilson is almost entirely forgotten by modern Christians. Yet his missionary labors on the coast of Western Africa (1834-1852), his service as Assistant Secretary of Foreign Missions for the Old School Presbyterian Church (1853-1861), and his service as the Secretary of Foreign Missions for the Southern Presbyterian Church (1861-1884) are exemplary in so many ways of a life devoted to spreading the gospel of Jesus far and wide. The reader will not quickly forget how God mightily used Wilson to bring the joy of the Lord Christ to the nations.
