The Holy Spirit, once forgotten, has been "rediscovered" in the twentieth century - or has he? Sinclair Ferguson believes we should rephrase this common assertion: "While his work has been recognized, the Spirit himself remains to many Christians an anonymous, faceless aspect of the divine being." In order to redress this balance, Ferguson seeks to recover the who of the Spirit fully as much as the what and how.

Ferguson's study is rooted and driven by the scriptural story of the Spirit in creation and redemption. Throughout he shows himself fully at home in the church's historical theology of the Spirit and conversant with the wide variety of contemporary Christians who have explored the doctrine of the Holy Spirit.
