In June of 2013, Elder L. Tom Perry described the impact of digital technologies on missionary work. He said:

“When I was a young missionary, we were able to speak with contacts on the street and knock on doors to share the gospel. The world has changed since that time. Now, many people are involved in the busyness of their lives. They hurry here and there, and they are often less willing to allow complete strangers to enter their homes, uninvited, to share a message of the restored gospel. Their main point of contact with others, even with close friends, is often via the Internet. The very nature of missionary work, therefore, must change if the Lord is to accomplish His work of gathering Israel ‘from the four corners of the earth’ (2 Nephi 21:12). The missionaries are now authorized to use the Internet in their proselyting efforts. …

“As missionaries enter this new age where they will use computers in the work of the Lord, we invite the young and the old, the adults, the young adults, the youth, and the children everywhere to join with us in this exciting new work by becoming Facebook friends with the missionaries in your area on your own computers and sharing their gospel messages online and by becoming involved in missionary work yourselves” (“Missionary Work in the Digital Age” [worldwide leadership training meeting, June 2013]; lds.org/broadcasts).
