Hunt has held ministry positions at Lavonia Baptist Church, Mooresboro, North Carolina (July 1976–August 1979), Falls Baptist Church in Wake Forest, North Carolina (1979–1980), Longleaf Baptist Church, Wilmington, North Carolina (May 1981–December 1, 1986), and at First Baptist Church in Woodstock, Georgia (1986 to December 2019).[6] First Baptist Woodstock is one of the largest churches in the United States. Under his ministry the church grew from about 1,000 to more than 19,000 members.[7]
In June 1996, Hunt was named the President of SBC Pastor's Conference. On March 11, 1997, the Johnny Hunt Chair of Biblical Preaching was established at the Southeastern Baptist Theological Seminary. In June 2008, Hunt succeeded Frank Pageaspresident of the Southern Baptist Convention, and served in that capacity for two years. He was succeeded by Bryant Wright.[8]
In November 2016, his church celebrated his 40 years in ministry and serving as senior pastor at First Baptist Woodstock Church for 30 years.
In August 2018, Hunt, alongside his wife Janet, announced to FBC-Woodstock that he would be transitioning out of his full-time pastoral position to fulfill a Senior VP ministry for the North American Mission Board. He stepped down after a tenure of 33 years.
In May 2022, Hunt resigned from the North American Mission Board after a report investigating the Southern Baptist Convention's handling of sex abuse cases was released and included an accusation that he had sexually assaulted another pastor's wife in 2010 which the report found credible. Hunt denied the accusation.[9] The Guideposts Report states: "We include this sexual assault allegation in the report because our investigators found the pastor and his wife to be credible; their report was corroborated in part by a counseling minister and three other credible witnesses; and our investigators did not find Dr. Hunt’s statements related to the sexual assault allegation to be credible."[10]
