J. Gresham Machen (1881–1937) taught New Testament at Princeton Theological Seminary from 1906 to 1929, when he founded Westminster Theological Seminary.

Does the gospel of Christ have a future in our increasingly secular world?
J. Gresham Machen, who paid a steep price, professionally and personally, for his adherence to the gospel, pondered that question in the writings that comprise this thought-provoking booklet:
• "The Gospel and the Modern World" (1929)
• "Selected Correspondence with Harold John Ockenga" (1931)
• "Preaching the Gospel in the Modern World" (1931)
• "Skyscrapers and Cathedrals" (1931)
