18 And I, Nephi, have written these things unto my people, that perhaps I might persuade them that they would remember the Lord their Redeemer.
This verse seems to be a wrap-up to a thought Nephi started
earlier in the chapter. In verse six he states that he would only include
sacred things in his engravings, and then he puts in a disclaimer that the
things included in the record are there because he thought they were sacred, and what some take to be sacred,
others disregarded. Verse seven has him using the Savior as an example of that
statement, how men trample under their feet even the very God of Israel. Verses
8–17 have Nephi quoting, paraphrasing, and commenting on the words of the
prophets regarding prophesies of Christ to testify that he really was their God.
Verse 18 seems to begin the conclusion to this topic. Nephi states why he is
writing all this, and it is for the express purpose that his people would
remember the Lord their Redeemer.
