It [the law] was designed, in the first instance, for the instruction of the Jews, now formed into a nation, and about to be established in the land which the Lord had promised to give to Abraham and his seed; and, in the second instance, to prepare them, by a course of discipline and education, for the coming of Him 'in whom all the families of the earth should be blessed.' They were put 'under tutors and governors until the time appointed of the Father,'—and 'the Law was their schoolmaster to bring them unto Christ, that they might be justified by faith.' For this reason it had a mixed character,—the 'Law' which came by Moses being 'added' to the 'Promise' which had been given to Abraham. It was neither purely Evangelical, nor purely Legal; it contained the Gospel, but 'the Law was added to it because of transgressions, till the Seed should come to whom the Promise was made.' The addition of the Law was not intended to alter either the ground, or the method, of a sinner's justification, by substituting obedience to the Law for faith in the Promise; for the Law which was originally 'ordained unto life' was now found, by reason of sin, 'to be unto death;' but it was now 'added,' and promulgated anew with awful sanctions amidst the thunderings and lightnings of Sinai, to impress the Jews, and through them the Church at large, with a sense of the holiness and justice of Him with whom they had to do,—of the spirituality and extent of that obedience which they owed to Him,—of the number and heinousness of their sins,—and of their utter inability to escape the wrath and curse of God, otherwise than by taking refuge in the free promise of His grace. Believers were justified, therefore, under the Law, not by works, but by faith: by faith, they were 'the children of Abraham,' and 'heirs with him of the same promise.' The Law—considered as a national covenant, by which their continued possession of the land of Canaan, and of all their privileges under the Theocracy, was left to depend on their external obedience to it,—might be called a national Covenant of Works, since their temporal welfare was suspended on the condition of their continued adherence to it; but, in that aspect of it, it had no relation to the spiritual salvation of individuals, otherwise than as this might be affected by their retaining, or forfeiting, their outward privileges and means of grace. It may be considered, however, in another light, as a re-exhibition of the original Covenant of Works, for the instruction of individual Jews in the principles of divine truth; for in some such light it is evidently presented in the writings of Paul. In this aspect, it was designed, not for the justification of sinners, but for the conviction of sin. In that form, it was afterwards employed even by the Apostles of Christ, to prove the impossibility of justification by the deeds of the Law, and the necessity of another righteousness, the righteousness of faith; and for the same end, it is still applied to the conscience by every faithful preacher of the Gospel. Thus considered,—as a re-exhibition of the Covenant of Works,—it had a tendency to produce 'a spirit of bondage unto fear;' and this would have been its only effect, had it not been associated with a revelation of God's purpose and promise of grace. But when the Gospel, which had been preached beforehand to Abraham, was known and believed, so as to impart a lively apprehension of 'the forgiveness which is with God,' then conviction of sin might become genuine contrition,—remorse might be turned into repentance,—and the more thoroughly the Law had done its work in the conscience, the more gladly would the promise of a Saviour be received into the heart. The economy of Moses, whatever prominence it gave to the Law, was unquestionably a dispensation of the Covenant of Grace. So far from superseding the promise given to Abraham, or 'making it void' and 'of none effect,' it was expressly founded upon it, and designed to carry it on to its accomplishment. That economy gathered up into itself all prior revelations of divine truth. It adopted also the Primæval and Patriarchal institutions—the Sabbath, Sacrifice, and Circumcision,—while it added to these a multitude of ordinances which were peculiar to itself—ceremonial and ritual observances, which were in themselves 'weak and beggarly elements,' and were felt to be 'a heavy yoke,'—yet they were all significant symbols, and typical prefigurations, of spiritual blessings. The believer, therefore, who could look beyond the sign to the thing signified, and see in the shadow the figure of the substance, might find Christ in every ordinance of the Old Testament Church, and obtain through Him, as revealed in the promise, forgiveness and acceptance with God. The devout Israelite, therefore, was justified by grace through faith, not less than the Christian believer. The divine Law, spiritually understood, awakened a deep conviction of sin; the divine promises, embodied and exhibited in the divine ordinances,—in those especially which related to the expiation of sin and the removal of ceremonial defilement,—pointed to a divine method of deliverance based on the principles of substitution and atonement, and produced trust in God's mercy and hope of His gracious acceptance; while the prospective character of these ordinances, as types of better things to come, and their utter insufficiency in themselves to 'take away sin,' or 'to make the comers thereunto perfect as pertaining to the conscience,' directed their thoughts forward to the time when the work of redemption should be actually accomplished by the promised Seed.
