When a person treats the information in an appropriate way, they "prove" themselves (Abraham 3: 25) worthy of weightier information to be given them. (D&C 132: 20-21.) Then they are laid under a strict command that they shall not impart, only according to the heed and diligence which another should give to the word. (Alma 12:9.)
Entrusting the things that are in truth "most sacred" to those who are not qualified will arouse their anger. They will "turn and rend you" because you have shown them something which excites their envy, jealousy, hatred and fear. They know you have something they lack. They resent you because of what they cannot easily obtain. Therefore, you must measure carefully what you give to others. The final arbiter of the decision to impart is not made by you, it is made by the Lord.
Those who are eager to share with others any tidbit of information they learn about the sacred are not helping anyone, and may forfeit things themselves. Why would they do such a thing? Is it to make themselves look good; therefore vanity? Is it to try to help others? If it is to help, then the information should not be shared; the manner in which the information is gained should be shared. Teaching another the way to receive sacred information for themselves is charitable. Showing off sacred information is worse than foolish, it will bless no one, and destroy both the unprepared audience and the unwise speaker.
Getting to know the Lord is the definition of salvation. (John 17: 3.) Getting to know me will save no one. It is foolish to consider anything or anyone more important than learning the means to come back to the Lord.
