This book attempts to demonstrate the interconnectedness between Old and New Testaments. The primary consideration being the application to one's personal salvation. The New Testament makes one's salvation contingent upon the works and merits of Christ. The same is demonstrated in the Old Testament in the person of the Servant, Who makes His soul an offering for sin. The messianic character of the Servant is easily demonstrated in His exaltation, in which a significant portion is spent in consideration. There are New Testament quotes of Old Testament psalms attributed to Christ, justification for such attribution being demonstrated. The Abrahamic covenant is considered in that the promise made to Abraham is codified in both the New and Davidic covenants. There is much consideration of the new covenant and how it is intertwined with both Israel and the church. The concept of being born again is shown to have roots in the Old Testament, with links to the new covenant. We finally consider saving faith as it pertains to the condition of the heart, both from an Old and New Testament perspective. In short, there appears a rather seamless connection between the two covenants. This runs counter to the impressions of many, to whom, on the surface, the Old and New Testaments are seemingly disjoint in their characteristics.
