When reading Vos’s sermons, it is helpful to read them as related to his books. For example, his sermon “The More Excellent Ministry” reads as a thesis for The Pauline Eschatology. “The Joy of Resurrection Life” provides even further context for understanding Jesus’s death and resurrection as the pivot of history, which is the central focus of Vos’s sermons. Vos’s sermons help the reader to understand that his books are eminently practical, drawing Christians to a deeper relationship with their Lord and savior.
