The Law was enacted with this promise attached to it: "This do, and thou shalt live." But man, by the total corruption of his nature, flowing from the original sin of Adam, is incapaciated from perfectly keeping this Law, and from working out any righteousness which can entitle him to heaven. But what man could not perform for himself, Christ hath done for man: He hath wrought out for him a perfect and everlasting righteousness. He, for man, was obedient to the Law, during His incarnation, in all its spiritual extent and requirements. And this vicarious sinless obedience of Christ is the justifying righteousness of the believer, and is his title to eternal glory: for this obedience of Christ is imputed to the believer in the same manner as the sins of the believer are imputed to Christ.
