Radical: Taking Back Your Faith from the American Dream

David Platt (b. 1978) is an American evangelical megachurch pastor and a bestselling author. Radical is his most widely known work, but he has written several other books as well (including a sequel, Radical Together). Platt grew up in Georgia and studied at the University of Georgia and New Orleans Baptist Theological Seminary (NOBTS), earning his PhD at the latter. He has been personally affiliated with the Southern Baptist Convention for most of his career, from his studies at NOBTS (a Southern Baptist ministry school) through his pastoral ministry. He began working in Christian ministry in New Orleans, serving both as the dean of the chapel and an associate professor at NOBTS, as well as pastor of Edgewater Baptist Church.

In 2006, he became the pastor of the Church at Brook Hills in Birmingham, Alabama—a congregation with a weekly attendance of over 4000—making him the youngest megachurch pastor (at 27 years old) in the USA. It was during his time at the Church at Brook Hills that Radical was written and published, released in 2010. Four years later, Platt resigned from the church to take a position as the president of the International Mission Board (IMB), the Southern Baptist mission agency and one of the largest Christian missionary organizations in the world.
