Law Not Contrary to Faith

The law evidently is not contrary to faith; otherwise God would be unlike himself; but we must return to a principle already noticed, that Paul's language is modified by the present aspect of the case. The contradiction between law and faith lies in the matter of justification. You will more easily unite fire and water, than reconcile these two statements, that men are justified by faith, and that they are justified by the law. “The law is not of faith;” that is, it has a method of justifying a man which is wholly at variance with faith.
