THE CHRISTIAN'S SECRET OF A HAPPY LIFE The premier line of Classic literature from the greatest Christian authors. The finest in quality and value.  Hannah Whitall Smith describes her book: This is not a theological book.  I frankly confess that I have not been trained in theological schools, and do not understand their methods nor their terms.  But the lord has taught me experiementally and practically certain lessons out of his Word, which have greatly helped me in my Christian life, and have made it a very happy one.  And I want to tell my secret, in the best way I can, in order that some others may be helped into a happy life also.
