First published in 1910, “The Person and Work of the Holy Spirit” by R. A. Torrey is the important and influential collection of sermons by the American pastor, educator, writer, and evangelist. Born Reuben Archer Torrey in New Jersey in 1856, Torrey was educated at Yale University and Yale Divinity School before becoming a minister in Ohio. Torrey later joined Dwight L. Moody in his evangelical work in Chicago and became the superintendent of the Bible Institute of the Chicago Evangelization Society, now the Moody Bible Institute. Torrey traveled all over the world to preach from 1902 to 1907, visiting China, Japan, Australia, India, Great Britain, and Canada. “The Person and the Work of the Holy Spirit” is considered one of his most important works and is based on sermons that he gave during his extensive travels. Torrey demonstrates his detailed knowledge of the scripture as he explores the important question of “who is the Holy Spirit?” He then shows how the devout may better know the Holy Spirit and receive his power and blessing. Torrey’s lessons continue to guide and instruct the faithful over a century after they were written.
