What does it mean to be clothed in the righteousness of Christ?

To be clothed in the righteousness of Christ refers to the imputation of Christ's righteousness to believers. As depicted in Zechariah 3, Joshua is stripped of his filthy garments and clothed with clean attire, symbolizing the righteousness that is conferred upon us through faith in Christ. This concept is foundational in Reformed theology, affirming that believers are accepted by God not based on their own works but entirely due to the perfect holiness of Christ. In this relationship, we are granted the privilege to stand before God as justified and sanctified, free from the guilt and power of sin.
