The Gospel, then, is of great antiquity. Older than the hills, older {XXVII} than the earth; for in the heavenly kingdom was it formulated before the foundations of the earth were laid. Nor were men left in ignorance of the plan of their redemption until the coming of the Messiah in the flesh. From the first that plan was known. Our annals are imperfect on that head, doubtless, but enough exists even in the Jewish scriptures to indicate the existence of a knowledge of the fact of the Atonement and of the redemption of man through that means. Abel, the son of Adam, is the first we read of in the Jewish scriptures as offering "the firstlings of his flock" as a sacrifice unto God. How came he to offer sacrifice of the firstlings of his flock? Doubtless behind Abel's sacrifice, as behind similar offerings in subsequent ages, stood the fact of the Christ's Atonement. [6] In it was figured forth the means of man's redemption--through a sacrifice, and that the sacrifice of the first-born. But where learned Abel to offer sacrifice if not from his father Adam? It is reasonably certain that Adam as well as Abel offered sacrifices, in like manner and for the same intent; and to Adam, though the Jewish scriptures are silent respecting it, God must have revealed both the necessity of offering sacrifice and the great thing of which it was but the symbol. And here, to some advantage, may be quoted a passage from the writings of Moses, as revealed to Joseph Smith, in December, 1830. From what was then made known to the great latter-day Prophet of the writings of Moses, it appears that our book of Genesis does not contain all that was revealed to Moses respecting the revelations of God to Adam and his children of the first generation. According to this more complete account of the revelation to Moses, after Adam was driven from Eden, God gave commandments both to him and his wife, that they should worship the Lord their God, and should offer the firstlings of their flocks for an offering unto the Lord, and Adam was obedient unto the commandment: And after many days an angel of the Lord appeared unto Adam, saying: Why doest thou offer sacrifices unto the Lord? And Adam said unto him: I know not, save the Lord commanded me. And the angel spake, saying: This thing is a similitude of the sacrifice of the Only Begotten of the Father, which is full of grace and truth. Wherefore, thou shalt do all that thou doest in the name of the Son, and thou shalt repent and call upon God in the name of the Son for evermore. [7] After some time elapsed and men multiplied in the earth and wickedness increased; after Abel, the righteous, was slain and Cain was a vagabond in the earth for the murder; after Lamech had also become a murderer and Satan had great power among the disobedient--then, it is written:
