Why is it important that Jesus is our only righteousness?

The importance of Christ as our only righteousness is emphasized in Philippians 3:9, where Paul speaks of being found in Christ, not having a righteousness of his own but that which is through faith in Christ. This highlights that human righteousness cannot meet God's perfect standard, as all have sinned and fall short of the glory of God (Romans 3:23). Therefore, only the perfect righteousness of Jesus, which is imputed to believers, can satisfy God's requirements for salvation and provide assurance of eternal life.
