How do we know Jesus is the fulfillment of the Old Testament prophecies?

The New Testament asserts that Jesus is the fulfillment of the Old Testament prophecies, as affirmed by passages such as Matthew 1:21 and Luke 24:44. Jesus Himself claimed that the Scriptures testify about Him, marking Him as the connection between the Old and New Covenants. His birth, death, and resurrection were foretold by prophets who spoke by the Spirit of Christ (1 Peter 1:10-11), showing that all of Scripture points to His redemptive work. Particularly, Hannah’s experience in 1 Samuel serves as a precursor to the larger narrative of salvation, foreshadowing Mary's own joy at bearing the Messiah. This consistent revelation throughout Scripture affirms Jesus' identity as the Savior of His people, the anointed King who fulfills God’s redemptive plan.
