The LORD brought Israel, a seed of Abraham, out of Egypt to make them into His own possession, a kingdom of priests and a holy nation. They would enter a covenant for this privileged relationship with the holy God, and they would do so on His terms, the law. Although they entered this covenant with their eyes wide open (informed and aware of the solemnity of this covenant), they failed to be faithful. They violated this covenant and demonstrated that they needed a new heart by the grace of God (Deut. 30:6). Though they failed to be God’s true son (4:22), that holy and royal priesthood, Jesus fulfilled. He became all that Israel should’ve been and thus fulfilled the Father’s plan for the ultimate seed of Abraham who blesses all the nations as their priest and king, and how Peter applies this reality to the church is most stunning.
