I have often thought about this and now know the answer. It by use of a simple sales technique. The only way on earth to influence other people to talk about what they want and show them how to get it.
Talk about what they want: everyone wants to see the end of crime, disease, hunger, death, old age, and would it not be great to see your dead mother, father, child, or aunt again on earth by means of a resurection? And the big one, not having to die at all.
Show them how to get it: All you have to do is get baptized, go to 5 meetings a week, go from door to door, study the same information over and over, be no part of the world, don't ask questiions. etc.
