Dr. A.J. Gordon was the founder of Gordon College of Theology and Missions and wrote one of the classics on the subject of the work of the Holy Spirit. The Ministry of the Spirit combines devotional examination of the scriptural teaching with a powerful challenge for the church. It is not claimed that in this little volume all has been said that might be said upon the subject treated. On the contrary, the writer has proceeded upon the belief that the doctrine of the Holy Spirit can be better understood by limiting the sphere of discussion, rather than by extending it to the largest bounds. For finite beings, at least, presence is more intelligible than omnipresence. So, though the subject of this book is in itself profoundly mysterious, we have sought to simplify it by dwelling upon the time-ministry of the Holy Ghost without entering upon the consideration of his eternal ministry. What the Spirit did before the incarnation of Christ, and what he may do hereafter beyond the second advent of Christ, is a question hardly touched upon in this volume. We have sought rather to emphasize and to magnify the great truth that the Paraclete is now present in the church: that we are living in the dispensation of the Spirit, with all the unspeakable blessing for the church and for the world which this economy provides. Hence, as we speak of the ministry of Christ meaning a service embraced within defined limits, so we name this volume the "Ministry of the Spirit," as referring to the work of the Comforter extending from Pentecost to the end of this dispensation. How deep a subject for a study! What prayer more becoming for those entering upon it than the humble petition that the Spirit himself will teach us concerning the Spirit! Deeply sensible of the imperfection of this work, it is now committed to the use and blessing of that Divine Person of the Godhead of whom it so unworthily speaks.
