Wigglesworth worked as a plumber, but he abandoned this trade because he was too busy for it after he started preaching. In 1907, Wigglesworth visited Alexander Boddy during the Sunderland Revival, and following a laying-on of hands from Alexander's wife, Mary Boddy, he experienced speaking in tongues. He spoke at some of the Assemblies of God events in Great Britain. He also received ministerial credentials with the Assemblies of God in the United States, where he evangelized from 1924 to 1929.
