This book contains the substance of lectures delivered to the members of the Society of Sacred Study in the Dioceses of S. Asaph and Bangor. Within the narrow compass of its pages there is obviously no pretense to completeness of treatment. The author only desired to make some suggestions for further thought and study. Contents: prophecy the chief mode of inspiration; divination in early Hebrew religion; psychology of divination; transition from divination to prophecy; prophetic excitation, its psychological conditions; prophetic audition; prophetic vision in Amos, Isaiah, Jeremiah and Ezekiel; psychology of false prophecy; gift of prophecy at Pentecost; tongues and their interpretation in the Corinthian Church; prophecy in the Corinthian Church; spirits of the prophets.
