Noel Perkin, a banker-turned-missionary, led Assemblies of God World Missions (AGWM) for more than thirty years (1927-59). His life exemplifies the missionary zeal historians have noted within the early Pentecostal movement. Perkin's experience of the Holy Spirit and his experiences as a missionary in Argentina led him to create systems intended to empower others to fulfill Christ's commission to make disciples of all nations. Perkin's empowering leadership played a significant part in AGWM's remarkable growth into a leading Pentecostal mission-sending agency which currently sends over 2,000 missionaries to 140 countries. As one of the principal architects of AGWM's missiology and operation, Perkin transformed a two-person office relying on envelope boxes for its accounting system into a well-structured, strategic mission agency and laid a foundation for AGWM's continued growth. Empowering Spirit, Empowering Structures uses the foundation of a biographical study to examine the concept of empowerment through Perkin's life and the impact that Perkin and his missiology had and continues to have upon AGWM.
