2 Nephi Chapter 33

33:1 - "...neither am I mighty in writing, like unto speaking..."
Nephi was not mighty in writing, but in speaking he was.  One example of this is in 1 Nephi 4:1-3 - where Nephi gives an amazing motivational speech to his brothers.  He understands public speaking very well.  I think I need to learn more public speaking...but mainly speaking by the power of the Holy Ghost, because that's when it makes a difference!

33:10-12 - "...and if ye shall believe in Christ ye will believe in these words, for they are the words of Christ..."
The Book of Mormon testifies of Christ...and if we believe in Christ, we will also believe in the words in the Book of Mormon.  This is because they are the words of Christ, and if we truly study, we come to understand that it is another testament of Jesus Christ.  Our behavior will change as we appreciate more fully the meaning of that statement.  We will study more intently the teachings in the Book of Mormon because applying those teachings will bring us to Christ, and help us become like Him.  That's our work.  Then we will help uthers repent and follow that same course.  That is our glory.
 
33:15 - "...for thus hath the Lord commanded me, and I must obey..."
When we receive commandments and promptints from the Lord, we must obey.  As we do this, we will have the Holy Ghost with us more, because we're acting in faith and putting ourselves into a position to be more receptive to the Spirit.  Joseph Smith understood this: "I made this my rule: When the Lord commands, do it." (Teachings of Presidents of the Church: Joseph Smith (2007), 160).
We must follow the Spirit, as well as the Lord's commandments.
