The Gospel in the Old Testament and Its Fulfillment
The gospel is deeply rooted in the Old Testament, with numerous prophecies and promises that find their fulfillment in Jesus Christ. The concept of the gospel is first introduced in the Old Testament through various passages that foretell the coming of a savior. For instance, Isaiah 61:1-3 speaks of one who will bring good tidings to the afflicted, and this is later fulfilled in Jesus' ministry [1].
The Old Testament prophets anticipated the gospel, and their writings contain numerous references to the coming Messiah. The Hebrew term "Messiah" (mashiah) means "anointed one," and it is used to describe the expected savior who would be anointed by God [3]. The New Testament writers saw Jesus as the fulfillment of these Old Testament prophecies, and they frequently cited passages from the Hebrew scriptures to demonstrate this connection.
The Gospel of Matthew, in particular, highlights the fulfillment of Old Testament prophecies in Jesus' life and ministry. For example, Matthew 1:22-23 quotes Isaiah 7:14, showing how Jesus' virgin birth fulfilled this prophecy. Similarly, Matthew 12:17 cites Isaiah 42:1-4, demonstrating Jesus' role as the servant of the Lord [5].
The New Testament writers also understood the gospel as a fulfillment of the Old Testament covenant promises. The book of Hebrews, for instance, presents Jesus as the mediator of a new covenant, one that is superior to the old covenant [7]. This new covenant is based on the sacrifice of Jesus Christ, which provides forgiveness for sins and an eternal inheritance for believers [8].
The apostle Paul wrote that the gospel was "promised beforehand through His prophets in the Holy Scriptures" (Romans 1:2) [4]. This underscores the continuity between the Old and New Testaments, with the gospel being the fulfillment of God's promises to his people. The gospel is not a new or separate message, but rather the culmination of God's redemptive plan, which was initiated in the Old Testament.
The fulfillment of Old Testament prophecies in Jesus Christ demonstrates the unity and coherence of the biblical narrative. As the Tyndale House commentary on Matthew notes, Jesus' actions consistently fulfilled Old Testament promises regarding the Kingdom and the Messiah [6]. This understanding of the gospel as the fulfillment of Old Testament prophecies has been a cornerstone of Christian theology, shaping the way Christians understand the relationship between the two testaments. The New Testament is considered the "new testament" in contrast to the old covenant, emphasizing its fresh and flourishing nature [2].

"The covenant of grace is called new; it succeeds to the old broken covenant of works. It is ever fresh, flourishing, and excellent; and under the gospel it is dispensed in a more clear, spiritual, extensive, and powerful manner than of old" (Brown of Haddington). Hence is derived the name given to the latter portion of the Bible. (See [438]TESTAMENT.)”

The great Messiah is anointed "above his fellows" (Ps. 45:7); i.e., he embraces in himself all the three offices.
