George Smeaton (1814-89) Scottish theologian, was among the numerous ministers who emerged in 1843 during the Disruption to form the Free Church of Scotland. Amongst the best known of the Puritans, John Owen (1616-1683) was a profound and thought provoking pastor-theologian. His writings continue to be widely read and greatly appreciated to this day.

”George Smeaton and John Owen have written with characteristic depth on the person and work of the Holy Spirit. Their work, however, can feel somewhat daunting to the contemporary reader and so the treasure remains unearthed. This book resolves that difficulty. A really helpful doorway into the doctrine; it is lucid, accessible and surprisingly thorough for such a short volume. Readers will find it clarifies and edifies in equal measure.“Reuben Hunter(Pastor, Trinity West Church, London)
