Paul addresses a profound shift in understanding righteousness. The Gentiles, who were not part of the Jewish law and tradition, have found righteousness through faith in Jesus Christ. This was unexpected because they were not actively pursuing righteousness through the law, as the Jews were. Instead, they embraced the message of the Gospel and were justified by faith. This highlights the inclusive nature of God's salvation plan, which is available to all, regardless of their previous religious background or efforts to adhere to the law.
The verse emphasizes that righteousness is not achieved by human effort or adherence to the law, but through faith in Christ. This challenges the traditional Jewish belief that righteousness was attained through the law and underscores the new covenant established through Jesus. It invites believers to understand that faith, rather than works, is the key to righteousness. This message is a cornerstone of Christian belief, emphasizing grace and faith over legalistic adherence to religious rules.
