Jesus is confirmed as the promised Savior through the prophecy of His lineage and His fulfillment of God's promises.
Jesus being the Savior is rooted in the promise of God, highlighted in Acts 13:23. This is tied to the lineage of David, as Jesus is referred to as the 'son of David.' The prophetic nature of Scripture validates His identity. Furthermore, the immutability of God's promises assures us that what God enacts cannot fail. This is a profound truth; while human promises can falter, God's promises are eternally secure, underpinning the faith we have in Jesus as our only Savior.
