Things Unseen

What Theologians Are Saying

  • “Virtually every page bristles with ideas for preaching and communicating the great doctrines of the faith...An unparalleled storehouse of great illustrations, delineations, and arguments for Christian doctrines. There is nothing quite like it.” —Tim Keller
  • “It is not always the case that an individual with such massive learning is as gifted a popular communicator as Machen...There is no dichotomy here between the preacher, the biblical scholar, and the systematic theologian. For orthodoxy, clarity, and sheer gospel verve they are hard to beat.” —Sinclair Ferguson
  • “The recovery of this work of J. Gresham Machen is not like finding a gold mine in the mountains, it is more like discovering a diamond mine. It is a true treasure—one of sparkling jewels and glorious truth. To mine this treasure is to find a deposit in heaven.” —R. C. Sproul
  • “Truly great biblical doctrine does not become outdated...Dominant in Machen’s address is, in a word, the gospel...A significant influence in my life, and I have had occasion to return to them always with great profit.” —Richard B. Gaffin, Jr.
  • “With the exegetical skills of a renowned New Testament scholar, the passionate precision of a defender of the faith, and the sweet sympathy of a human being, Machen treats theology as urgent life-and-death communication. Some of his references might be dated (by nine decades or so), but the substance remains as relevant as ever. I can think of few teachers of the past who are more reliable and rewarding to read, and now we can read his insights across the whole span of Christian doctrine.” —Michael Horton
  • “J. Gresham Machen was a man of his times, enmeshed in protracted and penetrating conflict over the triumphant liberalism of his day. He was also a man who transcended his times, because he undertook, with rare learning and clear-sighted understanding, the defense of the faith ‘once for all entrusted to God’s holy people’ (Jude 3). His Christianity and Liberalism, for instance, written almost a century ago, still sounds amazingly prophetic. This present volume brings together 50 of Machen’s radio talks of the 1930s, preserving Machen’s voice and emphases in an idiom that is more popular than his more academic books, but no less important. Machen is always worth reading.” —D. A. Carson
  • “J. Gresham Machen was one of the most prescient and courageous Christian theologians of the early 20th century. During his life, Machen was a clear and consistent voice for Christian orthodoxy and evangelical truth in the face of liberalism. This collection of lectures is a valuable addition to the Machen library. They reflect the heart of Machen’s ministry and provide yet another compelling presentation of Reformed Christianity. Machen’s works are as relevant now as they were when they were first written. These lectures are no exception.” —Albert Mohler
  • “In J. Gresham Machen, God gave the church an inimitable champion of biblical orthodoxy and gospel clarity. This book will show you why Machen is one of American evangelicalism’s most important 20th-century thinkers. More to the point, this book will ground you firmly in what it means to see in the face of Jesus Christ the grace and truth and glory of God.” —Russel Moore
