The Old Testament is foundational; the New Testament builds on that foundation with further revelation from God. The Old Testament establishes principles that are seen to be illustrative of New Testament truths. The Old Testament contains many prophecies that are fulfilled in the New. The Old Testament provides the history of a people; the New Testament focus is on a Person. The Old Testament shows the wrath of God against sin (with glimpses of His grace); the New Testament shows the grace of God toward sinners (with glimpses of His wrath).
