How do we know Jesus kept the law perfectly?

Scripture clearly states that Jesus kept the law perfectly, fulfilling every aspect of it—moral, ceremonial, and civic—expressed in Matthew 5:17 where He said, 'I came not to abolish but to fulfill the law.' This fulfillment is essential for our justification, as no one else has the capability to meet the demands of God's holy standard. The law serves as an indictment against our inability to obey. Jesus, as the true vine, maintained that perfect obedience and provides the only means through which we can abide in God's grace and righteousness.
