How do we know that justification cannot come through the law?

The Apostle Paul emphatically states in Galatians 3:11, 'But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.' This assertion underscores core Reformed theology, which teaches that justification is by faith alone in Christ alone and not by any works of the law. The law serves to reveal our sinfulness and our inability to attain righteousness on our own. Attempting to be justified by the law only leads to condemnation because, as the Bible teaches, breaking one point of the law makes one guilty of all. Thus, reliance on the law for justification is a grave misunderstanding of God’s plan of salvation.
