John MacArthur is an American pastor, author, and Bible teacher, best known for his long tenure as the senior pastor of Grace Community Church in Sun Valley, California, a position he has held since 1969. Born on June 19, 1939, in Los Angeles, MacArthur is a prominent figure in evangelical Christianity, especially within the Reformed and conservative theological circles. He is also the president of The Master’s University and The Master’s Seminary, institutions committed to biblical education and training for ministry. MacArthur is widely recognized for his verse-by-verse expository preaching and for his extensive body of written work, which includes the MacArthur Study Bible and dozens of books on theology, Christian living, and pastoral ministry. A vocal advocate of biblical inerrancy and a critic of modern evangelical trends, MacArthur has often been a polarizing figure, known for his uncompromising stances on doctrinal issues.
