Petto: Christ Satisfied the Law

Some think the righteousness of Jesus Christ, or his active obedience in our stead, needless; unless as a part of his satisfaction for sin; because (say they) the law requires not of us both suffering and obedience. I Answer, the Law, as a Covenant of Works, required suffering in satisfaction for sin, and as it belongeth to the Covenant of Grace, so it requireth perfect obedience (to be fulfilled by Jesus Christ) as the condition of the Justification and Life of sinners.
