How can a sinner be made righteous before God?

The doctrine of justification teaches that a sinner cannot earn righteousness through their own works or adherence to the law. Instead, righteousness before God is granted through faith in Jesus Christ (Philippians 3:9). It is by grace that we are saved, receiving Christ's perfect righteousness as a gift. The Apostle Paul exemplifies this truth when he expresses his desire to 'be found in Him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ' (Philippians 3:9). This underscores the importance of reliance on Christ alone for our standing before God.
