How do we know that Jesus is the Savior mentioned in the Bible?

The affirmation of Jesus as the Savior is deeply rooted in Scripture, beginning with prophecies in the Old Testament promising the coming Messiah. For example, Isaiah 53 elaborates on the suffering servant who bears our iniquities. In the New Testament, Simeon in Luke 2:30 calls Jesus 'your salvation,' highlighting that He fulfills God's promise of deliverance. The convergence of prophecy, His miraculous birth, life, death, and resurrection collectively substantiate His identity as the Savior—an essential truth for believers in the sovereign grace tradition.
