When theologian J. Gresham Machen died suddenly during a visit to North Dakota on New Year’s Day, 1937, he left unfinished one of the most innovative theological projects of his time. For the last two years of his life, Machen had begun work on what he hoped would be an accessible four part introduction to Christian theology. Only, he wasn’t just writing. He was broadcasting. Throughout 1935 and 1936, WIP radio in Philadelphia broadcast 50 of Machen’s “little talks,” as he called them, introducing listeners to profound doctrines in a popular and exciting format.     Machen’s complete radio talks have now been collected into a single volume titled “Things Unseen” with an introduction by Tim Keller, a foreword by Sinclair Ferguson, and more.  Over the next few weeks, we’re going to share some specially selected chapters from the audiobook of “Things Unseen.” I hope you’ll listen in and enjoy experiencing these talks the way their author intended.
