2 Nephi Chapter 32

32:2 - "...after ye had received the Holy Ghost ye could speak with the tongue of Angels..."
This may be talking about the gift of tongues, or being able to speak in other languages so other people could understand and be edified by the message...but it also could entail speaking as though you were an angel sent by God.
It's definitely something to think about...if God can trust you and send you to deliver a message, why would He send an angel if you could have that opportunity to serve and grow?  At that time, you are the angel needed.  We need to be ready at any moment to be ready to help anybody that needs it.  We can be ready by preparing as outlined in the next verse.

32:3 - "...feast upon the words of Christ..."
If we feast upon the words of Christ, we will have divine guidance and revelation to accomplish God's will when it is needed.
Elder Spencer J. Condie (November 2007 Ensign, pg. 16-18) talked about this and said that feasting upon the words of Christ is one way to receive the exceeding great and precious promises of the gospel (see 1 Nephi 19:23).
If we do what's required, we will be blessed.

32:4-5,8-9 - "...if ye cannot understand them it will be because ye ask not..."
It works together - we don't understand because we don't ask.  If we ask, then work to apply what we do know, we will receive more answers as we need them.  The trick is to not listen to Satan, who tells us not to pray.  It's subtle sometimes.  We reach a point where we want to be acting in faith, but then we neglect asking in faith.  There needs to be a good balance between the two.  The more we understand our relationship with God, the more natural our prayers become.  We want to talk to Him.

32:7 - "...knowledge...is given unto them in plainness..."
The Jews sought deeper - maybe for more understanding, or maybe to avoid understanding...but whatever the reason, the result was that they missed the mark.
We need to understand plainly the gospel; a great teacher can take a seemingly complicated principle and break it down to make it plain.  We must do this in our own teaching and learning.
