The Role of the New Testament

The New Testament reveals the fulfillment of God’s promises, introduces the new covenant through Jesus, and shows the foundation of the Christian church. Where the Old Testament promised a Savior, the New Testament reveals Him. Where the Old presented shadows and types, the New provides clarity and completion.

Jesus Christ is the central figure of the New Testament. His life, death, and resurrection are not just historical events—they are the turning point of human history. The New Testament testifies to this reality and teaches how followers of Christ are to live in light of that truth.

How the New Testament Connects to the Old Testament

The New Testament does not replace the Old—it fulfills it. The Old Testament is full of prophecies, symbols, and promises that find their meaning in Christ. Together, both parts of the Bible tell one unified story of redemption.

Examples of cross-references:

• Matthew 1:22–23 fulfills Isaiah 7:14 – the virgin birth prophecy.
• Hebrews 10:1 explains that Old Testament sacrifices pointed to Jesus.
• Luke 24:27 shows Jesus explaining how the Law, Prophets, and Psalms all point to Him.
• Galatians 3:16 connects God’s promise to Abraham with the coming of Christ.

The New Testament frequently quotes the Old Testament, building upon its foundation. It cannot be properly understood apart from the Old Testament, just as the Old Testament finds its full meaning in the New.

The New Testament contains 27 books that fulfill, explain, and expand upon the promises made in the Old Testament. From the birth of Jesus to the spread of the early church and the final hope of Christ’s return, the New Testament reveals God’s ultimate plan to redeem and restore through His Son.

Two testaments. One Savior. One eternal Gospel. Together, the Old and New Testaments tell the complete story of God’s love and redemption for the world.
