Is there any group of people on the Earth today that should be easier to baptize than the FLDS?
They already have a testimony of Joseph Smith and the BoM. They already have a testimony of Brigham Young and John Taylor. All we have to do is convince them that Wilford Woodruff really was a prophet, and they’re in. They probably haven’t ever really prayed to find out if the LDS church is true, and if they did, they must be close enough to the Holy Ghost for God to testify to them of their error.
Instead of sending missionaries to areas of the world with incredibly low rates of conversion and huge cultural and religious obstacles (Japan?), we should be blitzing Colorado City, where everyone is a dry Mormon with the same concern to resolve.
