The Church of Jesus Christ of Latter-day Saints Missions
Young people are encouraged to go on missions when they get old enough. Before an August 2012 change in church policy, men had to be 18 in most countries, and women throughout the world 21, before they could go on missions. More men go on missions than women do. The Church tells them where they need to go. Missionaries will go to people who live near them and teach them about the Church, and baptize people who want to join the Church. They also help people around them, even if these people are not in the Church. Often they help by building houses for people who need them.
