This first volume of Sermons by Jonathan Edwards on the Matthean Parables contains a previously unpublished series by Edwards on Jesus’ Parable of the Wise and Foolish Virgins, as found in Matthew 25. Edwards preached these sermons in 1737-38, in the lull between the Connecticut Valley Revival of 1734-35 and the Great Awakening, which started in Massachusetts in late 1740. Not only does this series have significance for its place in the Protestant evangelical awakening of the eighteenth century, but it is also an important index of Edwards’ developing thought on the nature of sainthood and related topics of theoretical and practical Christianity, particularly in the context of widespread spiritual renewal. To assist the reader, preceding the series are two introductions that describe Edwards’ preaching style and method and provide an historical context for the series itself. Prepared from the original manuscripts by the staff of the Jonathan Edwards Center at Yale University, this series represents a significant addition to the available Edwards corpus that will be of interest to scholars, religious leaders, and general readers.
