Reformed theology has been immensely influential in the West and in evangelicalism. Every believer, Reformed or not, will profit from a thoughtful reading of Grace Unknown. Few evangelical Christians today understand Reformed theology. They know it has something to do with predestination, and they may have heard of "the five points." But they can't name these points, and they think no one believes most of them anymore. R. C. says there's more to Reformed theology than these five points, so he devotes the first half of Grace Unknown to its most foundational doctrines. In the second half he explains each of the five points, showing their source in Scripture and their coherence with each other. Reformed theology reveals just how awesome the grace of God is. This doctrine has eluded so many evangelical Christians that true grace is, in some respects, unknown. In Grace Unknown R. C. explains "the heart of Reformed theology" and makes plain the reality of God's amazing grace.

Dr. R.C. Sproul (1939–2017) was founder of Ligonier Ministries, an international Christian discipleship organization located near Orlando, Fla. He was founding pastor of Saint Andrew’s Chapel in Sanford, Fla., first president of Reformation Bible College, and executive editor of Tabletalk magazine. Ligonier Ministries began in 1971 as the Ligonier Valley Study Center in Ligonier, Pa. In an effort to respond more effectively to the growing demand for Dr. Sproul’s teachings and the ministry’s other educational resources, the general offices were moved to Orlando in 1984, and the ministry was renamed. Dr. Sproul’s radio program, Renewing Your Mind, is still broadcast daily on hundreds of radio stations around the world and can also be heard online. Dr. Sproul produced hundreds of lecture series and recorded numerous video series on subjects such as the history of philosophy, theology, Bible study, apologetics, and Christian living. He contributed dozens of articles to national evangelical publications, spoke at conferences, churches, and academic institutions around the world, and wrote more than one hundred books, including The Holiness of God, Chosen by God, and Everyone’s a Theologian. He signed the 1978 Chicago Statement on Biblical Inerrancy and wrote a commentary on that document. He also served as general editor of the Reformation Study Bible, previously known as the New Geneva Study Bible. Dr. Sproul had a distinguished academic teaching career at various colleges and seminaries, including Reformed Theological Seminary in Orlando and Jackson, Miss. He was ordained as a teaching elder in the Presbyterian Church in America.
