Helaman 14 - 16

At the command of an angel, Samuel, the Lamanite returned to the Nephites to say -

"...ye shall hear my words, for, for this intent have I come up upon the walls of this city, that ye might hear and know of the judgments of God which do await you because of your iniquities, and also that ye might know the conditions of repentance..." (Book of Mormon Helaman 14:11)

"And also that ye might know of the coming of Jesus Christ, the Son of God, the Father of heaven and of earth, the Creator of all things from the beginning; and that ye might know of the signs of his coming, to the intent that ye might believe on his name." (Book of Mormon Helaman 14:12)

But not only the signs of his coming, but also

"...a sign of his death." (Book of Mormon Helaman 14:14)

"For behold, he surely must die that salvation may come; yea, it behooveth him and becometh expedient that he dieth, to bring to pass the resurrection of the dead, that thereby men may be brought into the presence of the Lord." (Book of Mormon Helaman 14:15)

Suggesting that not being in the presence of Lord or and endless seperation is a very real death or spiritual death, for the Savior -

"...redeemeth all mankind from the first death—that spiritual death; for all mankind, by the fall of Adam being cut off from the presence of the Lord, are considered as dead, both as to things temporal and to things spiritual.
17 But behold, the resurrection of Christ redeemeth mankind, yea, even all mankind, and bringeth them back into the presence of the Lord." (Book of Mormon Helaman 14:16 - 17)

But only to the extent to be -

"...brought to stand before the bar of God, to be judged of him according to their works whether they be good or whether they be evil—
11 If they be good, to the resurrection of endless life and happiness; and if they be evil, to the resurrection of endless damnation, being delivered up to the devil, who hath subjected them, which is damnation—" (Book of Mormon Mosiah 16:10 - 11)

The latter again being a spiritual death. The glad tidings of great joy is that the atonement -

"...bringeth to pass the condition of repentance, that whosoever repenteth the same is not hewn down and cast into the fire; but whosoever repenteth not is hewn down and cast into the fire; and there cometh upon them again a spiritual death, yea, a second death, for they are cut off again as to things pertaining to righteousness.
19 Therefore repent ye, repent ye, lest by knowing these things and not doing them ye shall suffer yourselves to come under condemnation, and ye are brought down unto this second death." (Book of Mormon Helaman 14:18 - 19)

For -

"...whosoever will believe might be saved, and that whosoever will not believe, a righteous judgment might come upon them; and also if they are condemned they bring upon themselves their own condemnation." (Book of Mormon Helaman 14:29)

The Lord has set the conditions of mercy. It is our burden to comply!

"...remember, remember...that whosoever perisheth, perisheth unto himself; and whosoever doeth iniquity, doeth it unto himself; for behold, ye are free; ye are permitted to act for yourselves; for behold, God hath given unto you a knowledge and he hath made you free.
31 He hath given unto you that ye might know good from evil, and he hath given unto you that ye might choose life or death; and ye can do good and be restored unto that which is good, or have that which is good restored unto you; or ye can do evil, and have that which is evil restored unto you." (Book of Mormon Helaman 14:30 - 31)
