Turretin on Gospel Growth
Francis Turretin (1623-1687):
As faith is the instrument of justification by receiving the righteousness of Christ, so it is the root and principle of sanctification, while it purges the heart and works through love. Justification itself (which brings the remission of sins) does not carry with it the permission or license to sin (as the Epicureans hold), but ought to enkindle the desire of piety and the practice of holiness. . . . Thus justification stands related to sanctification as the means to the end.--Institutes of Elenctic Theology (3 vols; P&R 1994), 2:692-93
