Joseph Smale (1867-1926) was one of the central figures involved in the chain of events leading to the 1906 Azusa Street Revival in Los Angeles. This important study presents the diverse influences which impacted Smale - formative years in Britain, growing up in Cornwall and Somerset amid a rhythm of Wesleyan revival; Reformed theological training under the tutelage of C.H. Spurgeon in London; migration to the United States; plus hard experiences in the ‘school of anxiety’ - which were all precursors for Smale’s influential role as champion of Pentecostal revival. Smale’s leadership will resonate with every church leader who prays for revival and longs for more Holy Spirit power experimentally. Smale’s ‘Moses’ designation and biography have profound relevance for the church in the present day.
