How do we know the law cannot save us?

Scripture clearly teaches that the law cannot save. In Galatians 3:21, it states, 'If there had been a law given which could have given life, verily righteousness should have been by the law.' The law serves to highlight our guilt and our inability to meet God's standards, ultimately emphasizing that our salvation must come through faith in Christ alone. Paul’s writings continually reaffirm that those who are under the law are under a curse if they rely on their works for righteousness (Galatians 3:10). The realization that we can do nothing to earn salvation leads us to trust fully in Jesus Christ, who has fulfilled the law on our behalf.
