Speak only per D&C 52:14-19, "He that speaketh...". That is well worth reviewing (with section 50 also).

• D&C 52:13-19 (Learn the behaviors. It talks about how to judge ... all ... under the whole heaven: you and I have spirits too) dnc 52 main
• Be gentle. The Savior's way of teaching is very instructive (as in a somewhat recent conference talk, like maybe 2019-4 or before).
• Be certain the service is done in humility, & harmony w/ Him, not thinking mainly of oneself.
