The Jehovah of the heavens stood before the people in Bountiful, clothed in a resurrected body. Thus, when he declares that he is the origin of the law, it is both the firm foundation upon which the new law will be built, but it is also a declaration that he was the author of the law that was old. To make the connection between the old and new, he brings up the prophets again. He will give new commandments, but just as with the prophets of old, the message is that we owe God obedience to whatever God’s commandments might be. The prophets had testified of the importance of keeping covenants and commandments. They knew of Christ, and knew that those fundamental principles would remain.
