Here's something copied from Mormon.org:
"If you’ve seen them walking, riding their bikes or driving around your town, you’ve probably wondered what Mormon missionaries are doing, exactly.
Why would these young men and women choose to put on their dress clothes and traipse around strange parts of the world for two years? The Lord’s Church has always been a missionary church. Just as Jesus Christ and His disciples preached the gospel, more than 50,000 missionaries for The Church of Jesus Christ of Latter-day Saints are spreading His word today. They are called to preach the gospel of Jesus Christ in all parts of the world. Most missionaries are about 20 years old, though many older married couples also choose to serve. Missionaries voluntarily put aside school, work and dating for about two years in order to serve the Lord at their own expense. Communication with family is even limited to letters or email and very occasional phone calls so that they can focus wholeheartedly on serving the Lord and the people where they serve. During their two years of full time service they devote themselves to studying, meeting people and teaching about Jesus Christ and His restored Church. Their work is a labor of love, and most missionaries end up feeling they gained more than they gave by serving."
People from all around the world are like me sharing our message!
Yeah, I'm doing what they are doing, pretty cool.
