Pres. Ezra Taft Benson gave a talk in 1998 on Flooding the Earth with the Book of Mormon.
The basic premise of his sermon was that the Book of Mormon is the "most correct book of any on the Earth," and it should be used as the Latter-day Saint's greatest weapon in furthering the kingdom of God. He challenged members to use the Book of Mormon in their gospel sharing, and trust in its power to help others come to Christ.
Well, the church just made it easier.
Church developers have created a mobile app of the Book of Mormon, but without the footnotes, superfluous links and other works of scripture available in the popular Gospel Library app. The new app is available on iTunes, the Google Play store, and the Windows marketplace.
Still no word on a Blackberry app. But you can always try this format.
