We know Jesus is the promised seed through prophetic scripture and His fulfillment of the requirements laid out in Genesis 3:15.
The identity of Jesus as the promised seed is confirmed through various Old Testament prophecies and their fulfillment in the New Testament. Genesis 3:15 serves as the first prophetic announcement of a Savior who would come to crush the serpent's head, which is ultimately fulfilled in Christ's death and resurrection. Throughout scripture, Jesus is continually referenced as the promised Messiah who was to be born of a virgin (Isaiah 7:14) and the one through whom God's redemptive plan unfolds. Believers can trace the lineage and fulfillments that point directly to Christ, affirming His role as the promised seed.
