Angels
In Mormon discourse angels are usually heavenly messengers whose purpose is not just to give information to human beings but to teach and instruct them on how to build heavenly conditions on earth, culminating in the construction of heavenly cities, including the City of Enoch, Zion, or the New Jerusalem. These celestial habitations are characterized by immortality, sustainability, abundance, and the presence of God.
Be not forgetful to entertain strangers: for thereby some have entertained angels unawares.
Do ye not remember that I said unto you that after ye had received the Holy Ghost ye could speak with the tongue of angels? And now, how could ye speak with the tongue of angels save it were by the Holy Ghost? Angels speak by the power of the Holy Ghost; wherefore, they speak the words of Christ. Wherefore, I said unto you, feast upon the words of Christ; for behold, the words of Christ will tell you all things what ye should do.”
