Some missionaries are called to service as Church Service Missionaries such as
in a ward in a different stake. Some are called to service in the Family History
Libraries around the world as well as here in Salt Lake. some, mostly the
younger sisters are called to work in Temple Square. It doesn't matter
where they serve just as long as THEY SERVE there fellow man
"helping in the community" you talk as though that is something new.
Service has long been a valuable tool in missionary service to replace tracting.
Some areas are making the change more recently but cautions are certainly
implemented in using social media.
What happens when Mormon missionaries can use the Internet? Well, if my mission
proved anything, very bad things. Missionaries need to get out on the street and
start helping and interacting with the community. Quit knocking on doors, that
only puts people off. Let the area members do that. Get involved with doing
things that benefit the community daily and the community will begin to open
there hearts to the message through example.
