President Boyd K. Packer, President of the Quorum of the Twelve Apostles, explained that teaching about sin in too much detail may stir one’s curiosity to experiment with sin:
“I am convinced that two of the major mistakes are to teach too much about the subject and to teach it at the wrong time. …
“I know of more than one instance in which a young person has been led to experiment in gross and perverted immorality because of a suggestion that originated with his bishop in an interview.
“Those who teach, and I refer to leaders, to teachers, and to parents, should keep in mind this message. Picture a father and mother leaving home for a period of time. Just as they go out the door they say to their little children who are to be left untended during their absence, ‘Now children, be good. Whatever you do while we are gone, do not take the footstool into the pantry, and do not climb to the fourth shelf and move the cracker box and reach back and get the sack of beans and take a bean and put it up your nose, will you?’
“Some of us are just that foolish. The humor of the illustration is wry humor when you think of the first thing that happens after the parents are gone. Surely we can be wiser than that. Young people should know from the very beginning that chastity is a sacred subject” (Teach Ye Diligently [1975], 256–57).
