The Law of Moses was, we may say, prophetic. It commanded sacrifice, which was indicative of the great Sacrifice that was to be made. Its performances and ordinances were visible signs of the Messiah whose coming they foretold. We place on record here as the best comment, the testimony of King Benjamin:
And the Lord God hath sent his holy prophets among all the children of men, to declare these things to every kindred, nation, and tongue, that thereby whosoever should believe that Christ should come, the same might receive remission of their sins, and rejoice with exceeding great joy, even as though he had already come among them.
Yet the Lord saw that his people were a stiffnecked people, and he appointed unto them a law, even the law of Moses.
And many signs, and wonders, and types, and shadows showed he unto them, concerning his coming; and also holy prophets spake unto them concerning his coming; and yet they hardened their hearts, and understood not that the law of Moses availeth nothing, except it were through the atonement of his blood.
(Mosiah 3:13-15)
