As part of William Durham's Full Gospel Assembly in Chicago, McPherson became known for interpreting glossolalia, translating the words of people speaking in tongues. Unable to find fulfillment as a housewife, in 1913, McPherson began evangelizing, holding tent revivals across the Sawdust Trail. McPherson quickly amassed a large following, often having to relocate to larger buildings to accommodate growing crowds. She emulated the enthusiasm of Pentecostal meetings but avoided their unbridled chaos, in which participants would shout, tremble on the floor, and speak in tongues. McPherson set up a separate tent area for such displays of religious fervor, which could be off-putting to larger audiences.
