What does the Bible say about the law's inability to save?

The law, represented by Moses, denotes our inability to attain righteousness on our own due to the weakness of our flesh. In Romans 8:3, it states, 'For what the law could not do in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh.' This underlines that the law cannot redeem; instead, it points us to our need for grace and salvation through Jesus Christ, our Savior, who fulfills the law's requirements and gives us life.
