Why is the law unable to save us?

The law serves to expose human sinfulness and the inability of individuals to attain righteousness through their own efforts. Galatians 3:10 elucidates this: 'For as many as are of the works of the law are under the curse; for it is written, Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.' This illustrates that the law requires perfect obedience, which none of us can achieve. Therefore, instead of leading to salvation, the law points us to our need for a Savior, making it clear that redemption is found only in Christ's perfect obedience and sacrifice.
