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.

What does Romans 3:20 mean?

Romans 3:20 says that no one can be made right with God by doing what the law commands, because the law’s main role is to make people aware of their sin. The verse emphasizes that following rules alone cannot justify anyone in God’s eyes.

Paul is writing to believers in Rome, explaining that both Jews and non-Jews are under sin and cannot earn righteousness by their own efforts. In this verse, Paul highlights that the law, given by God, serves to reveal what sin is, not to provide a way for people to become righteous by their own deeds.

The Greek behind Romans 3:20

  • νόμος (nomos, G3551): This word means "law" and refers to the commandments and instructions given by God, especially those found in the Old Testament. Paul uses it here to show that the law’s purpose is not to justify but to expose sin.
  • ἔργα (erga, G2041): Translated as "deeds," this word means actions or works. Paul is pointing out that human actions, even those meant to keep the law, are not enough to make someone righteous before God.
  • ἐπίγνωσις (epignōsis, G1922): This word means "knowledge" or "recognition." Paul uses it to say that the law brings a clear understanding of what sin is, making people aware of their shortcomings.

Why Romans 3:20 matters

  • Romans 3:20 clears up the misunderstanding that obeying religious rules or doing good deeds can make someone right with God; instead, it shows that everyone falls short.
  • This verse highlights the law’s true purpose: to reveal sin and show people their need for something beyond their own efforts.
  • Romans 3:20 sets up the argument for why faith, rather than works, is needed for justification, connecting to Paul’s larger message in Romans about grace and salvation.
