Why I Believe is a program that explores conversion and why we as members of The Church of Jesus Christ of Latter-day Saints believe in certain principles of the gospel. Conversion stories are shared by individuals who have had their lives touched and have become converted to the gospel of Jesus Christ, and doctrines and principles of the gospel are explored.
Five missionaries who served in St. Petersburg, Russia, talk about their experience. They discuss their initial impression of the call to serve and their first impression when they got there. They also speak about conversion stories of members they taught. The missionaries also talk about how their service in Russia changed their outlook on life and changed them into who they are today.
