The word revival might evoke anything from “holy rollers” and false prophets to street corner evangelism and tracts to deep repentance and renewed mission. In some circles, the word is a rallying cry. In others, it is a disappointment or even an embarrassment. InterVarsity vice president James Choung and young adult pastor Ryan Pfeiffer tackle these reactions head-on in their new book, Longing for Revival: From Holy Discontent to Breakthrough Faith. Drawing substantively from Scripture, global and historical Christianity, personal experience, and the writings of spiritual leaders and academics, Choung and Pfeiffer make the case that charismatic and noncharismatic Christians alike should desire revival and prepare themselves to participate in revival in a mature and strategic way.
