Animal Sacrifice and the Coat of Skins

Before Adam and Eve were cast out of the Garden of Eden, the Lord clothed them in the skins of an animal to provide a covering for them. In the Old Testament, the word atonement, in its various forms, appears 81 times. In 73 of those occurrences, the original Hebrew word is kaphar, which literally means “to cover.” After their expulsion from the garden, Adam and Eve were commanded to offer the firstlings of their flocks for an offering unto the Lord. An angel later instructed them that this practice was “a similitude of the sacrifice of the Only Begotten of the Father” (Moses 5:7).
Animal sacrifices continued under the law of Moses, along with the ritual covering of those participating in priesthood ordinances. When we covenant with the Lord and receive His holy ordinances, His Atonement covers us so that we are no longer exposed to the full effects of the Fall of Adam. Jesus Christ is truly the Lamb of God who was sacrificed for us so that we no longer have to be subject to the effects of sin and death.

When Tempted to be casual in wearing of the Temple Garment Consider these points from above:

1. It is a gift from the Lord

2. We are to give the firstlings of our flocks...in our day can't we make it a priority to give "dress" as an offering.

3. It is a symbol of the covering of the atonement from death, sin--the fall of Adam. Should we not be clamoring and running for this salvation and covering.  

We need not expect to do this vast work for the dead in a short time.

As the Saints moved forward with this sacred work, “it soon became apparent that some had long records of their dead, for whom they wished to administer,” recalled Elder George A. Smith, a member of the Quorum of the Twelve. “This was seen to be but the beginning of an immense work, and that to administer all the ordinances of the Gospel to the hosts of the dead was no light task. Some of the Twelve asked Joseph if there could not be some shorter method of administering for so many. Joseph in effect replied: ‘The laws of the Lord are immutable; we must act in perfect compliance with what is revealed to us. We need not expect to do this vast work for the dead in a short time.’”
