The law was […] offered to fallen man in order that, lacking all faculty of fulfilling the law, he may fulfill it through Christ.
Therefore, the promulgation of the law to Israel on Mount Sinai was a very gracious act. (Johannes Wollebius, Compendium Theologiae Christinae, p. 76)
Throughout this series we have been answering the question from which we began, “how was Christ administered to the saints of the Old Testament?” We have shown that Christ was administered and dispensed by means of the Land and Seed promises, the ordained Sacrifices, the Sacrament of Circumcision, and we have for the last couple of posts been discussing the Law itself as part of the administration and dispensation of the one redemptive work of Christ to the saints of the Old Testament.
Contrary to the assumption of many, the Law was not simply a ministration of death (2 Cor. 3:7), that which slew Paul (Rom. 7:9), the sting of death (1 Cor. 15:56), etc., but was rather a very gracious act of God—a redeeming act of God—Christ Himself promulgating the Law to His own people from Mt. Sinai, carrying them on eagle’s wings through the Wilderness, and in the Law displaying His own perfect and most desirable character. As we discussed last time, the Law became death to apostate Jews, not because it was not holy, righteous, and good in itself, but because we are fallen and evil by nature. What the Jews had failed to see was the purpose of the Law, preferring in the pride of their uncircumcised hearts to “do this and live,” rather than believe in their hearts and confess with their mouths the faith that was by it brought near.
