"And it came to pass that in that same year in which [Ether] was cast out from among the people there began to be a great war among the people..." (Ether 13:15).
Moroni makes note of the fact that the war began in the very year that this prophet was cast out by the people. The ensuing war never ceases until the consumption decreed makes an entire end of the Jaredites. None of the "fair sons and daughters upon the face of the whole earth" repented of their sins, but persisted in a course that was contrary to the warnings of the Lord. He had sent a prophet among them warning them. This prophet taught them of "all things, from the beginning of man" yet the people chose to pursue their present course.
The perpetual war became so "swift and speedy" that there were none left to bury the dead (Ether 14:22). They left "the bodies of both men, women, and children strewed upon the face of the land, to become a prey to the worms of the flesh" (ibid.). The people who were left were tormented by the terrible scent upon all the face of the land, both day and night (Ether 14:23). Millions were destroyed (Ether 15:2).
"And thus we see that the Lord did visit them in the fulness of his wrath, and their wickedness and abominations had prepared a way for their everlasting destruction" (Ether 14:25).
At last, when men were nigh unto death they "began to remember" the words of Ether and of all the prophets (Ether 15:1, 3). Still, few chose to repent. These were exceedingly sorrowful times (Ether 15:16-17). The people could not pull themselves away from the fighting because "the Spirit of the Lord had ceased striving with them, and Satan had full power" over their hearts (Ether 15:19).
Ether had written an extensive record. Moroni wants us to understand that he deliberately chose which items from Ether's record to include in the plates we were going to receive. He explains that he gave not even "the hundredth part" to us (Ether 15:33). It is all the more significant, therefore, that Moroni includes what he does in the record. We must pay attention to those items he chose for inclusion in the record we have inherited.
Moroni saw the terrible scene of iniquity and destruction that will be poured out upon this land in our day. It was revealed by the Lord to the prophet Joseph Smith. The consumption decreed will eventually make an end of all nations (D&C 87:6; D&C 45:30-33). All people will be at war one with another (D&C 45:33). Disease will spread (D&C 45:31; D&C 29:14-21). The only place of safety will be Zion. The only promise of protection is to be clean from the blood and sins of this generation.
What a sad state; Satan's will to rule and reign with blood and horror completely enacted upon the earth. We should learn from history. We should also learn from prophets the Lord sends declaring the message of repentance. The Lord's victory seems too small.
God's sword is bathed in heaven, and shall fall upon the inhabitants of the earth (D&C 1:13). The telestial world and its inhabitants are almost utterly wasted before and at his coming, all to begin anew. The course of the Lord is one eternal round. In great mercy, he will ever gather his children -worlds without end.
