This article addresses paucity in literature on the conceptualising of the true nature of a Protestant revival. Through a literary review and document study, the article aims to compile a Protestant revival evaluation criterion (PREC) to assess protestant revivals. This was done by integrating the distinctives (characteristics) of Evangelical revivals throughout history as described by prominent scholars such as Armstrong, Cairns, Edwards, Lloyd-Jones and Sprague in general. In addition, various past and present examples and exponents of true and juxtaposing anti-revivals were investigated and beacons set for sustainable revival. From the PREC, three levels were established by which to assess revivals: individuals (micro), the church (meso) and surrounding communities (macro). For the case study, information was gleaned from multiple sources, including interviews, documents, sermons, newsletters, observations and research reports. Applying the PREC in a case study, demonstrates how it operates as a valuable tool; in this case, the revival among the Zulus in KwaSizabantu, South Africa.
