Originally published in 1883, Hannah Whitall Smith's book The Christian's Secret to a Happy Life is an extremely popular book of Christian mysticism and practical Holiness theology. She explains that life is made of difficulties and painful situations. But the first burden, which she believes to be the greatest burden we have to carry in life, is self. The most difficult thing we have to manage is self. Our own daily living, our feelings, our weaknesses, and temptations - these are the things that confuse us more than anything else.

Divided into three distinctive parts - life, Difficulties, Results - this book is one of the best christian classic ever written. If you read it, this book will have a profound effect on your life.
