J. I. Packer (1926–2020) is regarded as one of the most well-known theologians and influential evangelicals of our time. Once named to Time magazine's list of the 25 Most Influential Evangelicals in America, Packer wrote what many consider the definitive classic evangelical book of the twentieth century, Knowing God, which has sold more than one million copies in North America alone. As the author of forty-seven books, as well as untold numbers of journal articles, book reviews, dictionary entries, and forewords, Packer's prolific work has impacted countless pastors, thought leaders, theologians, and authors.
