Mormon's How Tos

4 Nephi 1:23 "rich because of their prosperity in Christ"
You can cross reference this to Mormon 5:10, where Mormon says: "realize and know from whence their blessings come"  This is the reason Mormon is including the pride cycle, so the people who read the book can realize the source of the problem, and know where their prosperity comes from so they don't fall into the same cycle.  Let's apply the wise words of this prophet!

4 Nephi 1: 41 "and they did... build up churches unto themselves" I had an interesting thought with this phrase: They did not build their churches unto God, the one who instigated the churches for them in the first place.  They were using things He created to build unto themselves.  We will get so much more out of life is we build the things in it unto their original creator - God.  A life dedicated to and built for the Lord will be a happy one. :)

Mormon 2: 26 "and did beat them nevertheless the strength of the Lord was not with us" Don't fight this way. Mormon is giving us examples of this so we can recognize when we fall into doing it.

Mormon 3:1 "preparing their lands and their arms against the time of battle" Mormon has definitely read his scriptures! He is applying the war tactics of Moroni. This reminds me to apply the words of the prophets, just like Mormon did.

Mormon 5:1 "and did repent of the oath which I had made that I would no more assist them" The word "repent" used here is interesting.  It reminds me that, though Mormon is probably the most righteous among them, he is still repenting and constantly turning to the Lord. Righteous people are always repenting, that's what makes them righteous.

Mormon 5:24 "tear you in pieces, and none can deliver" This is a portion of the same phrase from 3 Nephi 20:16 and 3 Nephi 21:12.  I'm still not sure exactly what it means. (Refer to this post, scroll down to 3 Nephi 20:16.)
