My favorite scripture from the Book of Mormon is Alma 33:16
"..Thou art angry, O Lord, with this people, because they will not understand thy mercies which thou hast bestowed upon them because of thy Son"
I love this scripture because I love the idea that God is frustrated when we don't understand how much he did for us, and how much he loves us, and how many times he will forgive us. I understand his frustration, and am trying to help others feel the joy of understanding how merciful he is.
