Samuel Miller’s Thoughts on Public Prayer (1849) is an important volume for teaching and ruling elders leading in corporate worship, as well as anyone who has to pray publicly, whether in family worship, social settings, or at other occasions. Miller lays out a history of public prayer, discusses liturgies, opens up frequent faults in public prayer, and shows forth the characteristics of a good public prayer, as well as the best means of attaining excellence in this gift and grace.
