How does Christ make us righteous?

The concept of imputed righteousness is foundational in Reformed theology and centers around the work of Christ. In 2 Corinthians 5:21, we learn that Christ was made sin for us so that we might become the righteousness of God in Him. His perfect obedience to the law fulfills the requirements for righteousness that we could never attain. Through His sacrifice on the cross, He paid the debt of sin for His people, enabling them to be counted as righteous before God. This transfer of righteousness is not merely a legal declaration but a transformation that occurs when one is united with Christ. Thus, believers are not just declared righteous; they are made righteous by the work and grace of Christ alone.
