Blessed Assurance is an insightful examination of evangelism as a powerful political tradition in America. Randall Balmer vividly illustrates the ebb and flow of our nation's religious past by analyzing apocalyptic movements at the turn of every century, our two great religious revivals, and the evangelical longing for a third. He explores the rise of evangelical groups from Methodists to the Disciples of Christ and charismatic leaders like Mary Baker Eddy and Jimmy Swaggart. He reminds us how the evangelical movement of today is informed by history and the impassioned struggle for the American Christian soul.
