“In view of the present-day tendency to emphasize the diversity of the contents of the Bible, it is not superfluous to call particular attention to the fact that it should be interpreted as a unity. And the first question that confronts the interpreter is that of the relation in which the Old and New Testaments stand to each other.

“Both the Old and the New Testament form essential parts of God’s special revelation. God is the Author of both, and in both has the same purpose in mind. They both contain the same doctrine of redemption, preach the same Christ, and impose upon men the same moral… duties. At the same time, the revelation they contain is progressive, and gradually increases in definiteness, clearness, and spiritual conception. As the New Testament is implicit in the Old, so the Old is explicit in the New. Therefore we say that… [t]he Old and New Testament [sic] constitute a unit.

The Word of God is an organic production, and consequently the separate books that constitute it are organically related to one another. The Holy Spirit so directed the human authors in writing the books of the Bible that their productions are mutually complementary. They are one in recording the work which God, in the execution of his divine plan, wrought in Christ for the redemption of a people that would glorify him eternally. The Old Testament reveals this work, first of all, historically in the formation and guidance of Israel as a nation. The poetical books and the wisdom literature disclose its fruit in the spiritual experiences and the practical life of God’s people. And the prophets view it in the light of God’s eternal council, emphasizing the failure of the people to live up to the divine requirements, and directing the hopes of the pious to the future. A similar line of development runs through the New Testament. The Gospels and Acts contain the history of the work of redemption in Christ. The Epistles reveal the effect of this work in the life and experience of the churches. And the Apocalypse discloses its final issue in rays of heavenly light” (Principles of Biblical Interpretation, pp. 134-135, 138-139).
