Adam Offers Sacrifices in Similitude of the Sacrifice of the Only Begotten
Moses 5:5–9
5 And he gave unto them commandments, 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 commandments of the Lord.
6 And after many days an angel of the Lord appeared unto Adam, saying: Why dost thou offer sacrifices unto the Lord? And Adam said unto him: I know not, save the Lord commanded me.
7 And then 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.
8 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 forevermore.
9 And in that day the Holy Ghost fell upon Adam, which beareth record of the Father and the Son, saying: I am the Only Begotten of the Father from the beginning, henceforth and forever, that as thou hast fallen thou mayest be redeemed, and all mankind, even as many as will.
Elder L. Tom Perry said:
“Our Father in Heaven understood the need for His children to be reminded of the promises He has made to us if we would obey His laws. In making such covenants, the Lord offered blessings in exchange for obedience to particular commandments. A plan was laid out for us from the very beginning. The central figure in his plan of salvation is our Lord and Savior, Jesus Christ. His atoning sacrifice for all mankind is the centerpiece of the history of our Father in Heaven’s children here on earth. Each of us who accepts the divine plan must accept the role of our Savior and covenant to keep His laws that our Father has developed for us. As we accept Christ in spirit and in deed, we may win our salvation. We read in the scriptures: ‘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 forevermore’ (Moses 5:8).
“Is it any wonder that the Lord, from the very beginning, wanted to keep His plan firmly fixed in the minds of His children here on earth? Among the laws given to Adam and Eve, the law of sacrifice was instituted to remind them of the great event that would occur in the meridian of time:
“‘And he gave unto them commandments, that they should worship the Lord their God, and [they] should offer the firstlings of their flocks, for an offering unto the Lord. And Adam was obedient unto the commandments of the Lord.
“‘And after many days an angel of the Lord appeared unto Adam, saying: Why dost thou offer sacrifices unto the Lord? And Adam said unto him: I know not, save the Lord commanded me.
“‘And then 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’ (Moses 5:5–7).
“From that time onward until the Savior came to earth, whenever the priesthood was present, man offered sacrifices to remind him of the time when the Son of Man would come to earth to make the supreme sacrifice for all of us.”
