What is the author's style in Experiencing the Depth of Jesus Christ: The Autobiography by Jeanne Marie Bouvier de la Motte Guyon?

The book is written entirely from Jeanne Guyon's perspective with the exception of the Epilogue which is written by the publishers of this version and is meant not to extend on her work but to offer some additional information and explanation. The first person perspective is personalized by Guyon's writing style which is aimed at the reader. She frequently uses the word "you," and this adds a personal touch that some readers may appreciate.

The first person and personal perspective is the only possible option, especially considering that the book was first written directly to friends. The information presented by Guyon is her way of communicating her own methods of reaching a deeper relationship with the Lord. With this as the goal of the story, first person is the only viable presentation available to Guyon.
