On a Sunday afternoon in 1935, J. Gresham Machen stepped into a broadcast booth at WIP Radio in Philadelphia and began something no one had tried before: teaching Reformed theology over the radio. In the vein of C.S. Lewis’s landmark “Mere Christianity” talks, Machen’s addresses are a crystal-clear articulation of the basics of the Christian faith, unfolding into an exceptional and persuasive explanation of Reformed theology.
Things Unseen is both an accessible systematic theology, and a masterclass in evangelistic apologetics.
Introduced by Timothy J. Keller, Foreword by Sinclair B. Ferguson, Historical Preface by Stephen J. Nichols, Afterword by Richard B. Gaffin, Jr.
“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, Founder, Ligonier Ministries
“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 Professor of Theology and Apologetics, Westminster Seminary California
“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). HisChristianity 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, Emeritus Professor of New Testament, Trinity Evangelical Divinity School
“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, President, The Southern Baptist Theological Seminary
“The life and teaching of J. Gresham Machen are rightly revered by contemporary Christians who prize Reformed orthodoxy. Machen’s compelling voice lives again in the pages of this masterful treatment of Christian doctrine. As a theologian for ordinary Christians, his clear and concise communication of biblical truth will draw new readers into a deeper and more personal knowledge of the risen Christ.”
Philip Ryken, President, Wheaton College
“J. Gresham Machen was one of the lions of Reformed evangelical thought in the 20th century. His clarity of thought and courage borne of a deep conviction and a personal walk with the God about whom he spoke and wrote suffuses this entire book. With disarming simplicity, Machen presents the most important truths in the world and challenges us all to take them seriously. We need more of such clarity and directness today.”
