Though her life was difficult, Hannah Whitall Smith's message was joyful. In the Christian's Secret of a Happy Life, she writes that "Jesus came to save you fully now, in this life, from the power and dominion of sin, and to deliver you altogether." Passionate and practical, Whitall Smith's classic of the Holiness movement focuses not on human effort but on simple, stubborn faith in the Savior and Sanctifier of the soul.

"Our part is the trusting," she writes, "it is His to accomplish the results."
