This inspired and inspiring book reflects on the Holy Spirit's action in the history of salvation. Its central point is Christ's pasch, his death, resurrection and glorification. While bot overlooking the riches of tradition or the insights of theology, Durrwell follows the approach of his justly famous book The Resurrection in letting his profound knowledge of Scripture lead him and his readers to a deeper understanding of who the Father and Christ for our salvation. The book is both an essay in Biblical theology and a stimulus reflection.
