"James Buchanan belonged to the bright galaxy of theologians who graced the early days of the Free Church of Scotland. His brilliant and uniquely conceived treatment of the Holy Spirit expounds his Ministry first biblically and theologically, then in a series of biographical studies, and finally systematically in the life of the Christian. Buchanan superbly combines the reliable with the readable, the doctrinal with the practical, the theological with the devotional. 'The Office and Work of the Holy Spirit' is a classic work on the Holy Spirit and a master class in theology." - Sinclair Ferguson
