Alma 19:9

9 And Ammon said unto her: Believest thou this? And she said unto him: I have had no witness save thy word, and the word of our servants; nevertheless I believe that it shall be according as thou hast said.

I've often wondered if her desire influenced her belief. But I really do think she believed. Really believed.

Just more proof that believing is an action that I can choose to DO, not a passive state or result of circumstances.
