What does the Bible say about Jesus being perfect?

Jesus Christ is described in Scripture as the only truly perfect child. Luke 2:39-40 notes that He grew in wisdom and grace, emphasizing His complete holiness and perfect fulfillment of the law. The historical necessity of His perfection lies in the fact that, as the Son of God, He was required to be without sin to serve as the perfect sacrifice for humanity's sins. His perfection is foundational for our salvation, as it is His righteousness that believers rely upon for justification before God.
