The gospel, or good news, of Jesus Christ was not a new concept introduced suddenly. It was part of God's divine plan, revealed through the prophets in the Old Testament. These prophets, inspired by God, spoke of a coming Messiah who would bring salvation to humanity. This promise is woven throughout the Scriptures, from the writings of Moses to the prophecies of Isaiah and beyond. By fulfilling these prophecies, Jesus Christ confirms the reliability and truth of God's word. This continuity between the Old and New Testaments underscores the faithfulness of God and His unwavering commitment to His people. Believers can find comfort and assurance in knowing that God's promises are steadfast and that His plan for redemption, as revealed through the prophets, has been fulfilled in Christ. This encourages a deeper trust in God's word and His promises, reinforcing the unity of the Scriptures and the central role of Jesus in God's redemptive plan.
Understanding this connection helps believers appreciate the depth and richness of the Bible, seeing it as a unified narrative of God's love and salvation. It also emphasizes the importance of the Old Testament as foundational to understanding the New Testament and the life and mission of Jesus.
