"In sincerity of heart"

1. Mosiah 4: 10
   10 And again, believe that ye must repent of your sins and forsake them, and humble yourselves before God; and ask in sincerity of heart that he would forgive you; and now, if you believe all these things see that ye do them.
2. Mosiah 26: 29
   29 Therefore I say unto you, Go; and whosoever transgresseth against me, him shall ye judge according to the sins which he has committed; and if he confess his sins before thee and me, and repenteth in the sincerity of his heart, him shall ye forgive, and I will forgive him also.
3. D&C 5: 24
   24 Behold, I say unto him, he exalts himself and does not humble himself sufficiently before me; but if he will bow down before me, and humble himself in mighty prayer and faith, in the sincerity of his heart, then will I grant unto him a view of the things which he desires to see.
