Geerhardus Vos, a pioneer in biblical theology, continues to influence Bible students today. Widely known for his scholarship on Vos, editor James T. Dennison Jr. here collects, for the first time, all of Vos's extant letters. Many of these letters were written to such luminaries as Abraham Kuyper, Herman Bavinck, B. B. Warfield, and J. Gresham Machen. The editor's notes to each letter assist the reader in understanding references in them.
