This publication is the first survey of Jonathan Edwards's harmonic interpretation of Epistle to the Hebrews. This methodology emphasized harmony between the history of the world and its account in the Word. Drawn from a planned publication on The Harmony of the Old and New Testament, the harmonic interpretation of Jonathan Edwards sought to harmonize the Old and New Testament by employing three habits: (1) the habit of observing Old Testament prophetic fulfillment in the person and work of Christ in the New Testament; (2) the habit of perceiving typology in the natural world and Scripture that typified the Messiah, Jesus Christ; (3) the habit of harmonizing the Old and New Testament according to its doctrines and precepts. After introducing this methodology to readers, this study provides eight thematic case studies on how Edwards demonstrated this methodology in his interpretation of the Epistle to the Hebrews.
