Healthful Living was originally published by the Medical Missionary Board, Battle Creek, Michigan, under the title Instruction Relating to the Principles of Healthful Living. It was so popular when it first came out that it became necessary to print a second and third edition the first year. We have reproduced the 1898 third edition, which also contained two additional chapters: "God in Nature" and "The Spirit Filled Life." In the third edition an appendix of parallel Scripture references was included. This Scripture referenced appendix will be found exceedingly helpful in making clear to the mind of the reader the fact that the principles presented in this work are not mere human inventions but are a part of the divine order appointed for the human family at the beginning, and which is to be restored when all things are made new. Wherever it has been received, this book has been recognized as a veritable storehouse of seed thoughts relating to the great practical themes with which it deals.
