"It is our duty to concentrate all our influence to make popular that which is sound and good and unpopular which is unsound." - Joseph Smith
Basically this quote is about putting good morals out there so people know and that that may change their ways. We tech lessons so people will learn. We bring certain topics to a new light to inform people. Being informed is what will create better lives. Sometimes it is difficult because some topics are considered taboo. So that makes things very inconvenient. Sometimes people are too stubborn to listen to reason or to communicate at all. I am not sure with the definition of popularity. I am assuming it means well known or liked by the majority. The main priority to influence people and to improve lives is to inform people. If people do not completely comprehend what is going on we will not be able to find a decent solution. Everyone has their own perspectives yet we fail to understand other's.
