In 3 Nephi 11, after he has appeared and the multitude has come forth and witnessed for themselves, Jesus calls Nephi and 11 others and speaks to them specifically about his doctrine. In verses 39-40, he says
After this, Mormon creates a break in Jesus' words (" it came to pass that when Jesus had spoken these words unto Nephi, and to those who had been called...").39 Verily, verily, I say unto you, that this is my , and whoso upon this buildeth upon my rock, and the of hell shall not prevail against them.40 And whoso shall more or less than this, and establish it for my doctrine, the same cometh of evil, and is not built upon my rock; but he buildeth upon a foundation, and the gates of hell stand open to receive such when the floods come and the winds beat upon them.
Then, Jesus again speaks to the multitude and gives the Sermon at the Temple that we know as the Sermon of the Mount in Matthew 5. As we know, this sermon ends with
Again, immediately after this, Mormon breaks it up: "And now it came to pass that when Jesus had ended these sayings". What follows is the talk on the other sheep and the gathering of Israel, healing of the sick, blessing the children and introducing the sacrament in chapters 16-18. After he has talked about the sacrament, towards the end of the first day of his ministry among the Nephites, Jesus says24 Therefore, whoso heareth these sayings of mine and doeth them, I will liken him unto a wise man, who built his house upon a —25 And the descended, and the floods came, and the winds blew, and beat upon that house; and it not, for it was founded upon a rock.26 And every one that heareth these sayings of mine and doeth them not shall be likened unto a man, who built his house upon the —27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell, and great was the fall of it. (3 Nephi 14)
After a few more verses, Mormon breaks it up again in verse 17: "And it came to pass that when Jesus had spoken these words unto his disciples...". This time Jesus says a few more words to the multitude before he gives his disciples the power to give the Holy Ghost and departs into heaven.12 And I give unto you a commandment that ye shall do these things. And if ye shall always do these things blessed are ye, for ye are built upon my .13 But whoso among you shall do or less than these are not built upon my rock, but are built upon a sandy foundation; and when the rain descends, and the floods come, and the winds blow, and beat upon them, they shall , and the of hell are ready open to receive them.
What did we observe here? Jesus repeats the theme of building upon his rock three times during the first day of his visit to the Nephites. These all somehow seem to mark the ending of a segment of that day. I find it peculiar and don't really know what to make of it. At the moment, I'm just fascinated by the complexity and structure of the Book of Mormon. Like I've said before, these intricate patterns are not created by a poor farmer dictating a text while looking in a hat.
But the message is quite clear anyway: We must give heed to the words of Christ and do according to them. Then we build upon the rock and get a sure foundation. This is the way of life. The alternative is not doing what he says or doing "more or less". This results in a sandy foundation and is the way of death.
