What does the Bible say about true righteousness?

The Bible emphasizes that true righteousness is not something that can be achieved through human effort or adherence to the law. In Romans 2, Paul explains that even those who follow the law are unable to fully meet God's standard of holiness due to their sinful nature. True righteousness is instead given to believers through faith in Jesus Christ, who is referred to as 'the Lord our righteousness,' as stated in Jeremiah 23:6. This righteousness is not based on our actions but is a free gift from God, freely bestowed upon those who put their trust in Christ.
