Besides this evangelical character which unquestionably belongs to the Mosaic covenant, it is presented in two other aspects in the Word of God. First, it was a national covenant with the Hebrew people. In this view the parties were God and the people of Israel; the promise was national security and prosperity; the condition was the obedience of the people as a nation to the Mosaic law; and the mediator was Moses. In this aspect it was a legal covenant. It said, “Do this and live.” Secondly, it contained, as does also the New Testament, a renewed proclamation of the original covenant of works. It is as true now as in the days of Adam, it always has been and always must be true, that rational creatures who perfectly obey the law of God are blessed in the enjoyment of his favour; and that those who sin are subject to his wrath and curse. Our Lord assured the young man who came to Him for instruction that if he kept the commandments he should live (emphasis added).
