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

The assurance that Jesus is the Savior described in the Bible stems from the comprehensive nature of scriptural testimony throughout both the Old and New Testaments. Prophets foretold His coming, and the attributes and roles assigned to Him in Scripture reflect His divine mission. For instance, in Isaiah, He is called 'Wonderful Counselor, Mighty God' (Isaiah 9:6), while the New Testament confirms His fulfillment of these prophecies through His life, death, and resurrection. All that Christ has accomplished was predestined, culminating in His identity as the perfect sacrifice who is capable of saving His people from their sins, as indicated in Matthew 1:21. This cohesive narrative affirms His divine purpose and the certainty of His role as our Redeemer.
