“therefore I make a record of my proceedings in my days”
Sometimes we assume that the book of 1 Nephi is like a journal – that he kept it as he went along. Maybe that’s the case for the other plates he kept, I don’t know, but with the version we have access to, Nephi wrote this record 30 years after Lehi’s family left Jerusalem, and well after the time they arrived in the Promised Land. (see 1 Nephi 19:1-5 / 2 Nephi 5:28-31)
Why does that matter, you ask? Well, it doesn’t, really. I just thought that was kind of cool.
Then again, maybe you could draw the lesson from it that keeping a journal is not enough, we should write our life history, too.
Okay, so maybe that’s not the intent, but that’s a good lesson, too!
