Charity is not an emotion or an action. It is not something we feel or do. Charity is who the Savior is. It is His most defining and dominant attribute. It is what enabled Him to endure the Garden and the cross for you and me. It is one of the things that makes Him God. Thus, when we plead for the gift of charity, we aren't asking for kind feelings toward someone who has wounded us. We are pleading for our very natures to be changed, for our character to become more and more like the Savior's, so that we literally feel as He would feel and do what He would do. This is why Mormon said that when the Savior appears, those who have been gifted with charity will be like him, for they will "see him as he is."
