We know Jesus is a successful Savior because Scripture affirms His divine mission will be accomplished without fail.
The assurance that Jesus is a successful Savior is deeply rooted in the promises of Scripture. Matthew 1:21 states emphatically, 'for he shall save his people from their sins,' indicating a certainty about His redemptive work. In contrast to other figures in the Bible, such as Moses who spoke of potential atonement, Jesus guarantees salvation. His mission is not merely an attempt but a definitive promise of victory over sin and death. Sovereign grace theology affirms that all those whom the Father has given to the Son will come to Him (John 6:37), indicating that Jesus will not lose any of His sheep. Therefore, His successful salvific work is assured and encompasses a specific people chosen before the foundation of the world, ensuring that when He says 'I will save,' it is an accomplished fact that brings glory to God.
