This volume looks at the Third Great Awakening, one of the most exciting times in the history of American Christianity. A. B. Simpson’s impact on the Third Great Awakening and his influence on the modern church is examined. Emphasis is placed on the denomination he founded, the Christian and Missionary Alliance. Simpson’s message, the Fourfold Gospel, is also explored. The Fourfold Gospel is: Christ as the Christian’s Savior, Sanctifier, Healer, and Coming King. The denomination Simpson founded took this message not only to North America, but also throughout the world. Five movements made up the Third Great Awakening and Simpson’s contribution to each one is examined. These five movements include: Evangelizing, Holiness Movement, Healing Movement, Pre-millenial Movement, and Urban and Worldwide Outreach. As this book concludes with a look at Simpson’s influence on the church today, we are reminded that as the church goes through the twenty-first century, the Fourfold Gospel continues to be proclaimed just as it was during the Third Great Awakening.
