How do we know that Christ fulfills the law?

In Romans 10, it is declared that 'Christ is the end of the law for righteousness to everyone who believes,' encapsulating the fact that His life and death satisfied the entirety of the law's demands. The Lord Jesus' fulfillment of the law not only silences the condemnation of the law but establishes a new standard of righteousness which is obtained by faith. With Christ’s sacrificial death, He has perfectly completed the work that the law aimed to achieve, giving believers liberty and a new status before God, which is based not on their performance, but on His grace and righteousness.
