There is only one obvious answer, these people are not hearing from God. If God was dwelling within them, and they heard the truth, then one would think the Spirit would stir inside them to confirm the truth. They would immediately repent, ask forgiveness, and sin no more.
I really believe that Elder Ephraim of Arizona is one of the exceptions!
(It is really worth watching it. I think he gives an answer to Daniel Larimer @ 43:10!)
Wait. Are you saying thay father Paisius is not an exception?
