A new video highlights Elizabeth McCune's missionary work.

Since President Thomas S. Monson's 2012 announcement reducing the minimum age for full-time missionary service, LDS men and women have joined the throng of proselytizing young adults in increasing numbers.

The Church of Jesus Christ of Latter-day Saints' growing missionary program now includes 20,000 single women whose predecessors are the subject of a video released Monday on the Mormon Newsroom website.

The video is part of a Church History Department series and focuses on Elizabeth McCune, a woman whose influence in England led to the calling of the first full-time sister missionaries in 1898.

Sister missionaries have received additional attention this week in a June 29 article in The Tampa Tribune. The article by Michelle Bearden highlights the two women's proselytizing efforts outside a Broadway performance of "The Book of Mormon" musical and emphasizes how their service has deepened their friendship and their commitment to the LDS Church.

"Going on a mission takes you out of yourself and puts the focus on others,” Jennifer Knight, author of a book for sister missionaries, told Bearden. “It cultivates the spirit like nothing else can. It’s life-altering, and it will forever change how you look at things.”
