How do we know the righteousness of Christ is our righteousness?

The righteousness of Christ is foundational to the Christian faith, particularly within the framework of sovereign grace theology. In Philippians 3:9, the Apostle Paul expresses his desire to be found in Christ, not having a righteousness of his own but that which comes through faith in Christ. This idea of 'imputed righteousness' signifies that Christ's perfect obedience and merits are counted as ours through faith, which is a central theme throughout the New Testament. This truth assures believers that they stand righteous before God, not based on their own merit but on Christ’s finished work, allowing them to have peace with God.
