Gordon B. Hinckley

You may think it is the macho thing to flare up in anger and swear and profane the name of the Lord.  It is not that macho thing.  It is an indication of weakness.  Anger is not an expression of strength.  It is an indication of one's inability to control his thoughts, words, his emotions.  Of course it is easy to get angry.  When the weakness of anger takes over, the strength of reason leaves.  Cultivate within yourselves the mighty power of self-discipline.

Gordon B. Hinckley, Ensign Now 1991, 49

Joseph Fielding Smith

I wonder if we ever stop to think why the Lord has asked us to pray. Did he ask us to pray because he wants us to bow down and worship him? Is that the main reason? I don't think it is. He is our Heavenly Father, and we have been commanded to worship him and pray to him in the name of his Beloved Son, Jesus Christ. But the Lord can get along without our prayers. His work will go on just the same, whether we pray or whether we do not. He knows the end from the beginning. ... Prayer is something that we need, not that the Lord needs. He knows just how to conduct his affairs and how to take care of them without any help from us. Our prayers are not for the purpose of telling him how to run his business. If we have any such idea as that, then of course we have the wrong idea. Our prayers are uttered more for our sakes, to build us up and give us strength and courage, and to increase our faith in him.
