In Galatians
2:16-21, Paul emphasizes that we have been justified (using the aorist tense) through faith in Jesus Christ, not by the works of the law, illustrating that he has been crucified with Christ and now lives by faith in the Son of God. This passage highlights the futility of seeking righteousness through the law and underscores the necessity of faith in Christ for true justification, demonstrating that righteousness is granted through God's grace, not human efforts.
