“Thirdly, I add ‘of a man justified’ for two causes. First, to show that justification and sanctification are two divers gifts of God, and their difference may appear in three things: first, in that justification is out of a man, sanctification is within him; secondly, justification absolves a sinner and makes him stand righteous at the bar of God’s judgment, sanctification cannot do this; thirdly, justification brings peace of conscience, so does not sanctification, but follows that peace. Thus, the apostle has them distinct: ‘Ye are washed, ye are justified and sanctified’ (1 Cor. 6:11). Christ is made to us righteousness and sanctification (1:30). Secondly, because justification goes with sanctification. Though justification be before in nature, yet they are wrought at the same time. For when God accepts a man’s person, then he is made just, who is also sanctified.”
