The material of this book has been before the Christian public for many years, and has been read by very many individuals, and the author has the best reasons for believing, with much affirmed interest and profit. During this period also the central theme of this book, "the Promise of the Spirit," "the Baptism of the Holy Ghost," the promised "Enduement of Power from on High," which became real in the experience of the apostles and their associates at the Pentecost, has become throughout Christendom a subject of thought, inquiry, prayer, and waiting expectation. That this book has contributed something to bring about this desirable and most propitious and hopeful consummation, is not a matter of doubt. That it may hereafter continue to exert an important influence to prepare the way for the approaching "brightness of the Divine rising," is still an object of hope.
