How do we know that Christ is the end of the law?

In Galatians 3:24, Paul tells us that the law was our schoolmaster to bring us to Christ, and according to Romans 10:4, 'For Christ is the end of the law for righteousness to everyone that believeth.' This means that through Christ's sacrificial death, the demands of the law have been satisfied, and believers are no longer under its authority for justification. Christ Himself stated in Matthew 5:17 that He came not to destroy the law but to fulfill it, which affirms His role as the completion of the law's demands, thus freeing those who believe from its bondage.
