Those He Justifies, He Sanctifies

For we dream neither of a faith devoid of good works nor of a justification that stands without them. This alone is of importance: having admitted that faith and good works must cleave together, we still lodge justification in faith, not in works. We have a ready explanation for doing this, provided we turn to Christ to whom our faith is directed an from who it receives its full strength.

Why, then, are we justified by faith? Because by faith we grasp Christ's righteousness, by which alone we are reconciled to God. Yet you could not grasp this without at the same time grasping sanctification also. For he "is given unto us for righteousness, wisdom, sanctification, and redemption" [1 Cor. 1:30]. Therefore Christ justifies no one whom he does not at the same time sanctify. These benefits are joined together by an everlasting and indissoluble bond, so that those whom he illumines by his wisdom, he redeems; those whom he redeems, he justifies; those whom he justifies, he sanctifies.
