The revised or fiftieth edition of our text-book, Science and Health, with Key to the Scriptures, is greeted with joy, gratitude and love by every Christian Scientist. A higher, purer consciousness of Truth, of Life, comes with its reading, which points unmistakably to the fact that the work of to-day is to give this book to the world as its healer and teacher; therefore, let us bear in mind the command of Jesus: "Let your light so shine before men that they may see your good works, and glorify your Father which is in heaven." (Matt. v.16.)
