How do we know Jesus is the promised Christ?

The identification of Jesus as the promised Christ is firmly rooted in His genealogical lineage as a descendant of David and Abraham, which is evidenced in Matthew 1:1. Furthermore, the Apostle Paul notes in 1 Corinthians 15 that the entirety of Jesus's life and mission was in accordance with the Scriptures. The testimonies found in both the Old and New Testaments consistently reveal His fulfilling role—He embodies the prophecies concerning the One who would save His people from their sins. Thus, through a confluence of prophecy, lineage, and fulfillment, we can confidently assert that Jesus is indeed the promised Christ.
