That “everlasting covenant” with Abraham was a covenant of faith. It was everlasting, and therefore the giving of the law could not disannul it. It was confirmed by the oath of God, and therefore the law could not add anything to it. Because the law added nothing to that covenant, and yet was not against its promises, it follows that the law was contained in its promises. The covenant of God with Abraham assured to him and his seed the righteousness of the law by faith. Not by works, but by faith. EVCO 328.1
