Luke 2:19; refer in this text to Alma 37:28; 2 Ne. 32:7
“It is not wise to continually talk of unusual spiritual experiences. They are to be guarded with care and shared only when the Spirit itself prompts you to use them to the blessing of others. I am ever mindful of Alma’s words (Alma 12:9). I heard President Marion G. Romney once counsel mission presidents and their wives … , ‘I do not tell all I know, … for I found out that if I talked too lightly of sacred things, thereafter the Lord would not trust me.” (Boyd K. Packer, Ensign, Jan. 1983, p. 53)
