God freely justifies the persons whom he effectually calls. He does this, not by infusing righteousness into them but by pardoning their sins and by accounting them, and accepting them as righteous. This He does for Christ's sake alone and not for anything wrought in them or done by them. The righteousness which is imputed to them, that is, reckoned to their account, is neither their faith nor the act of believing nor any obedience to the gospel which they have rendered, but Christ's obedience alone. Christ’s one obedience is twofold – His active obedience rendered to the entire divine law, and His passive obedience rendered in his death.
