How does the faith of Christ relate to the righteousness of believers?

The faith of Christ is foundational to the believer's righteousness, as stated in Philippians 3:9. Paul clarifies that it is not by one's own works or a self-made righteousness that we stand justified before God, but rather through Christ's actual faith and obedience. It is through this divine means that believers are accounted righteous, as Romans 3:22 illustrates that the righteousness of God is accessible through faith in Jesus Christ for all who believe. Hence, the righteousness of believers is ultimately grounded in Christ’s unwavering faithfulness.
