There’s so much in here, but I have time to pick out only a couple of verses:
Wherefore, when thou hast read the words which I have commanded thee, and obtained the witnesses which I have promised unto thee, then shalt thou seal up the book again, and hide it up unto me, that I may preserve the words which thou hast not read, until I shall see fit in mine own wisdom to reveal all things unto the children of men.
This one’s interesting because I suddenly realised it addresses a question I hadn’t thought about all that much (one of those “was this always in there?” moments). The question being why Joseph Smith had to give the plate back. The reason is given here :”that I may preserve the words which thou hast not read” (my emphasis). Never mind people attempting to retranslate the Book of Mormon itself: the concern given here is over the sealed portion, which the Lord has kept back at this time.
And they shall contend one with another; and their priests shall contend one with another, and they shall teach with their learning, and deny the Holy Ghost, which giveth utterance.
As I’ve mentioned before, one of the themes of 2 Nephi 25-30 is the way a contrast is built up between human learning and the knowledge from God, and this is an example, where contending priests are condemned for teaching by their learning while denying the Holy Ghost and true inspiration. I find it cautionary: in my approach to the scriptures, and when I discuss them with other people, how often do I rely on what I think I know rather than being open to the spirit to teach me things I don’t?
For behold, at that day shall he rage in the hearts of the children of men, and stir them up to anger against that which is good.
2 Nephi 28 also spends quite a bit of time talking about the different tactics of the devil, including flattery, complacency and in this case rage. A lot of present political developments are currently predicated on rage, of course, with people being “angry” and demanding that their anger be validated. And I’ve found in turn that there’s a strong temptation to be angry in turn with certain movements. Such unbridled anger, however, is a tool of the devil, and we/I have to be careful not to let him use such tools against us.
