We know the law cannot justify us because Galatians 2:16 says, 'no flesh will be justified by the works of the law.'
The inability of the law to justify us is a recurring theme in Paul's writings. In Galatians 2:16, Paul asserts, 'Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ.' This clearly indicates that justification—a lawful declaration of righteousness—is contingent solely upon faith in Christ, not adherence to the law. Furthermore, Romans 3:20 reinforces this by stating that 'therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.' The law's primary function is to reveal our sinfulness rather than provide a means of justification.
