"Adam and Eve were taught the law of sacrifice and were commanded to practice it by giving offerings. They obeyed without questioning… Adam and Eve were taught the law of sacrifice and were commanded to practice it by giving offerings. These included two emblems: the firstlings of the flock and the first fruits of the field. They obeyed without questioning (see Moses 5:5-6). President David O. McKay pointed out: “The effect of this [law] was that the best the earth produced, the best specimen in the flock or herd should not be used for self, but for God” (“The Atonement,” Instructor, Mar. 1959, 66). At a time in history when it was a struggle to make sure the family had food, those who sought to worship the Lord were asked to sacrifice the best part of their source of life. It was a real test of Adam and Eve’s faith, and they obeyed.
Likewise, Abel, Noah, Abraham, Isaac, Jacob, and all the holy prophets from Adam to Moses offered to the Lord sacrifices in a similar way.
The Law of Moses - Because of the rebellious nature of the children of Israel in the days of Moses, the practice of the law of sacrifice was changed; it became a strict law requiring daily observance of performances and ordinances. During the time of Moses there was an expansion in the number and variety of offerings under the law of sacrifice. The Mosaic sacrifices consisted of five major offerings that fell into two primary categories—obligatory and voluntary. The difference between the obligatory and the voluntary offerings might be compared to the difference between the law of tithing and the law of fast offerings.
One thing remained the same in all of these offerings: everything about Mosaic sacrifice focused on Christ. Like Christ, the priest acted as the mediator between the people and their God. Like Christ, the priest had to have the right parentage to officiate in his office. Like Christ, the offerer through obedience willingly sacrificed what was required by the law.
The part of sacrifice that most strongly paralleled the Savior was the offering itself. Notice with me some of these parallels.
First, like Christ, the animal was chosen and anointed by the laying on of hands. (The Hebrew title Messiah and the Greek title Christ both mean “the Anointed One.”) Second, the animal was to have its life’s blood spilt. Third, it had to be without blemish—totally free from physical flaws, complete, whole, and perfect. Fourth, the sacrifice had to be clean and worthy. Fifth, the sacrifice had to be domesticated; that is, not wild but tame and of help to man (see Lev. 1:2-3, 10; Lev. 22:21). Sixth and seventh, for the original sacrifice practiced by Adam and the most common sacrifice in the law of Moses, the animal had to be a firstborn and a male (see Ex 12:5; Lev. 1:3; Lev. 22:18-25). Eighth, the sacrifice of grain had to be ground into flour and made into breadstuffs, which reminds us of our Lord’s title the Bread of Life (see John 6:48).
Ninth, the firstfruits that were offered remind us that Christ was the firstfruits of the Resurrection (see I Cor. 15:20). (See also Bible Dictionary, “Sacrifices”; Daniel H. Ludlow, ed., Encyclopedia of Mormonism, 5 vols. , 3:1248–49.)” (Elder M. Russell Ballard, The Law of Sacrifice, Ensign, October 1998).
