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. Carolyn Nystrom (MA, Wheaton College) has written more than eighty books, Bible study guides, and children's titles. She coauthored Praying with theologian J. I. Packer and Is the Reformation Over with scholar Mark Noll. She is also the author of the LifeGuide Bible Studies 1& 2 Peter and Jude, Money and Work, Friendship, Listening to God and more. In addition to actively serving in her church, she has been a foster parent, an elementary schoolteacher, the stated clerk of her EPC presbytery, and a book editor. Carolyn lives in northern Illinois with her husband, and they have four grown children.
