How do we know Jesus is the Savior of our sins?

The certainty of Jesus as the Savior stems from His divinely appointed role as the Lamb of God. Acts 4:12 proclaims, 'Neither is there salvation in any other; for there is none other name under heaven given among men, whereby we must be saved.' This emphasizes that salvation is exclusive to Jesus, who, through His sacrificial death, provides complete and perfect atonement for sin. He is the one who not only carries our sins but also removes them entirely from us. As John stressed in his proclamation, understanding this truth requires spiritual revelation, which God grants to His chosen people.
