Receive the Holy Ghost

I'll cite Nephi's words in the beginning of 2 Nephi 32.

"Angels speak by the power of the Holy Ghost" and at the same time we're told that once we receive the Holy Ghost "ye could speak with the tongue of angels." In other words, what allows an angel to speak with such power and conviction are when they speak the words of Christ and they are carried to the listener by the "power of the Holy Ghost."

If man has the potential to speak with the tongue of angels (in other words, by the same power) then we have to acquire that power by "feasting upon the words of Christ that will tell us all things what we should do." When we feast upon the words of Christ, we'll find individual instruction and direction to "bring us into the light." To summarize the words of Nephi, "this is the doctrine of Christ."

How easily is that spirit offended? How easily will he depart from us and we lose that power? If we pray, feast upon the words of Christ, and follow the individual instruction we receive, then we can have the Holy Ghost as a guide and companion and speak with the tongue of angels.
