Mosiah 3

Christmas is a time we rejoice in the coming of the Savior. We rejoice because of His life and His -

"...infinite atonement..." (Book of Mormon 2 Nephi 9:7)

Jarom reports that -

"...the prophets, and the priests, and the teachers, did labor diligently...persuading them to look forward unto the Messiah, and believe in him to come as though he already was…" (Book of Mormon Jarom 1:11)

King Benjamin taught his people -

"...whosoever should believe that Christ should come, the same might receive remission of their sins, and rejoice with exceedingly great joy, even as though he had already come among them." Book of Mormon Mosiah 3:13)

All of these that looked forward to His coming celebrated the spirit of Christmas. Even before Adam we know that in a pre-existent state -

"...there were many of the noble and great ones..." (Pearl of Great Price Abraham 3:22)

We also know there were also the rebellious for -

"...the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him." (New Testament Revelation 12:9)

One would have to assume that with these extremes there must have been many in different stages of obedience in this pre-earth life suggesting that there was even then the requirement of "faith in the Lord Jesus Christ" and "repentance". Just the same hoped that they -

"...might receive remission of their sins, and rejoice with exceedingly great joy, even as though he had already come among them." Book of Mormon Mosiah 3:13)

We seen this -

"When the morning stars sang together, and all the sons of God shouted for joy?" (Old Testament Job 38:7)

It seems to be apparent that all in this pre-earth life must have celebrated the coming of the Savior.

We rejoice now with the coming of the Savior with Faith in the Lord Jesus Christ and the opportunity of repentance.

In the worlds to come, we will continue to possess agency. Though I do not know the meaning of all things, I assume because of agency and because of an infinite atonement, we will still need faith in the Lord Jesus Christ and repentance. Because of that through the eternities will continually "rejoice with exceedingly great joy". In other words, we will continue to celebrate the birth of the Savior
