Madam Guyon's correspondence was very extensive, occupying five printed volumes. Her style of writing is somewhat diffuse. In giving religious advice to many persons, there would necessarily be frequent repetitions. It has, therefore, occurred to the writer, that a selection and re-arrangement of thoughts, such as is found in this little volume, would be more acceptable and useful, than a literal and full translation of her letters. This selection necessarily involved much re-writing and condensing. Great care, however, has been taken to reach her true sentiments, and to give a just relation of her religious experience. In the interesting preface to her letters, published in 1767, the writer remarks: "Next to the Holy Scriptures, we do not believe there has been given to the world, any writings, so valuable as Madam Guyon's; and of all these precious treasures, her letters are the most rare. All who have received the unction of the Holy One, whereby they know the truth, are agreed upon her divine writings." If the writer may be permitted to add her humble testimony, having enjoyed the privilege of reading her writings in the original for several years, she would say, there are no writings, excepting the Sacred Oracles, from which she has received so much spiritual benefit. It is on this account, she has endeavored, with divine assistance, to portray to others, Madam Guyon's deep religious feelings. May the same spirit of devotion to her Lord and Master which she possessed, rest upon the heart of the reader. Happy are they in whose hearts burns the flame of divine love.
