This book grew out of a burning desire in the author's soul to tell to others what he himself so longed to know a quarter of a century ago. When the truth dawned upon him in all its preciousness, it seemed to him that he could point out the way to receive the desired blessing of the Holy Spirit more fully and plainly than other authors had done. The result of his effort to do so is found in Part III. of this volume. Those who are convinced that there is such a blessing for them, and are in haste to receive it, may begin to read at Part III.There are others who are in doubt about the theological and Scriptural standing of the doctrine of the instantaneous "baptism with the Holy Ghost," with its consequent "holiness and power." To them Part I. and Part II. are earnestly commended. We believe that the arguments there advanced are built on, and formed out of, the impregnable Rock of God's Word. We have avoided all fanciful and doubtful and forced interpretations of Scripture. Passing by all texts of questionable bearing, there are enough left and in such profusion and variety of form and expression as to make the argument, to our mind, simply unanswerable.
