The Mosaic Law is one of six covenants that God made with Israel, all six of which have five concepts in common: their authority resides in Him, they all came at a time of crisis, no covenant nullifies a previous one, salvation from sin is not obtained by keeping any covenant, and significant negative events followed the instigation of each. The theological context of the Mosaic Covenant is Israel’s election by grace and the redemptive context God’s deliverance of Israel from Egypt. The content of the covenant follows the pattern of the ancient suzerainty treaty. The covenant was the most conditional of all the covenants, and like all the covenants, it promised blessings for obedience and curses for disobedience. The covenant addressed itself to Israel and Israel alone with its divinely authoritative rules that stipulated standards of righteousness. No one can justly separate the moral, civil, and ceremonial parts of the Law from each other; it is a unit. The Law has no authority over Christians because it has been fulfilled by the death of Christ.
