One of my favorite things about the Book of Mormon is its pragmatic view of human nature. Undoubtedly, its authors knew the best and worst of the human experience, and weren’t pulling any punches.
An example of this is the honest depiction of missionary work here, namely its tediously frustrating reality. Though the Book of Mormon does have some more neutral general observations about how people are (such as here and here), most of the time the text is pessimistic.
Here are nine such passages:
O that cunning plan of the evil one! O the vainness, and the frailties, and the foolishness of men! When they are learned they think they are wise, and they hearken not unto the counsel of God, for they set it aside, supposing they know of themselves, wherefore, their wisdom is foolishness and it profiteth them not. And they shall perish.
And now I, Nephi, cannot say more; the Spirit stoppeth mine utterance, and I am left to mourn because of the unbelief, and the wickedness, and the ignorance, and the stiffneckedness of men; for they will not search knowledge, nor understand great knowledge, when it is given unto them in plainness, even as plain as word can be.
4. People tend to be easily swayed by charismatic leaders who promise them what they want
And there were many in the church who believed in the flattering words of Amalickiah, therefore they dissented even from the church; and thus were the affairs of the people of Nephi exceedingly precarious and dangerous, notwithstanding their great victory which they had had over the Lamanites, and their great rejoicings which they had had because of their deliverance by the hand of the Lord.
Thus we see how quick the children of men do forget the Lord their God, yea, how quick to do iniquity, and to be led away by the evil one.
And thus we see that except the Lord doth chasten his people with many afflictions, yea, except he doth visit them with death and with terror, and with famine and with all manner of pestilence, they will not remember him.
O how foolish, and how vain, and how evil, and devilish, and how quick to do iniquity, and how slow to do good, are the children of men; yea, how quick to hearken unto the words of the evil one, and to set their hearts upon the vain things of the world!
Behold ye are worse than they; for as the Lord liveth, if a prophet come among you and declareth unto you the word of the Lord, which testifieth of your sins and iniquities, ye are angry with him, and cast him out and seek all manner of ways to destroy him; yea, you will say that he is a false prophet, and that he is a sinner, and of the devil, because he testifieth that your deeds are evil.
But behold, if a man shall come among you and shall say: Do this, and there is no iniquity; do that and ye shall not suffer; yea, he will say: Walk after the pride of your own hearts; yea, walk after the pride of your eyes, and do whatsoever your heart desireth—and if a man shall come among you and say this, ye will receive him, and say that he is a prophet.
And it came to pass that thus passed away the ninety and fifth year also, and the people began to forget those signs and wonders which they had heard, and began to be less and less astonished at a sign or a wonder from heaven, insomuch that they began to be hard in their hearts, and blind in their minds, and began to disbelieve all which they had heard and seen–
Imagining up some vain thing in their hearts, that it was wrought by men and by the power of the devil, to lead away and deceive the hearts of the people; and thus did Satan get possession of the hearts of the people again, insomuch that he did blind their eyes and lead them away to believe that the doctrine of Christ was a foolish and a vain thing.
And it came to pass that the people began to wax strong in wickedness and abominations; and they did not believe that there should be any more signs or wonders given; and Satan did go about, leading away the hearts of the people, tempting them and causing them that they should do great wickedness in the land.
