Bob Mumford (July 22, 1930 – September 15, 2020) was an American preacher, Bible teacher, and author whose ministry profoundly influenced the charismatic movement through his emphasis on the Kingdom of God and personal spiritual growth. Born in Steubenville, Ohio, to a family that faced hardship after his parents’ divorce when he was 13, he left school to support his mother and five sisters. At 20, he joined the U.S. Navy as a Pharmacist’s Mate, where a dramatic conversion in 1954—while on leave attending a church service—shifted his life’s course. Discharged soon after, he enrolled at Valley Forge Christian College, graduating with a Bachelor of Science in Bible, and later earned a Master of Divinity from Reformed Episcopal Seminary in Philadelphia. In 1956, he married Judith, beginning a partnership that spanned his ministry. Mumford’s preaching career took off as he taught at Elim Bible Institute (1963–1970) and co-founded Christian Growth Ministries in 1970 with Derek Prince, Charles Simpson, Don Basham, and Ern Baxter, launching the controversial shepherding movement. His sermons, marked by humor and clarity, reached wide audiences through New Wine magazine and Lifechangers, a ministry he established in 1972 to distribute his teachings globally. Author of books like The Agape Road (2002) and Take Another Look at Guidance (1971), he addressed practical faith, though his role in shepherding drew criticism for authoritarianism, prompting a public apology in 1989. Father to Eric and Lisa with Judith, he resided in Raleigh, North Carolina, in his later years, leaving a legacy of mentorship and prophetic teaching until his death at 90.
