How do we know Jesus is our perfect Savior?

The assurance of Jesus as our perfect Savior lies in His dual nature as both God and man, which allows Him to embody the perfection required by God's law. Jotham, in the story of Judges, represents this perfect Savior whose very name means 'Jehovah is perfect'. The New Testament reinforces this, claiming that Jesus was without sin and bore our sins on the cross, making Him our righteousness before God. Therefore, He fulfills God's requirement for perfection, providing hope and salvation to His people.
