I was going to write a snarly little response because I don't have much trouble with my children being contentious with each other--instead, I have a huge problem with me creating contention by being a grump.
Instead, I'm going to refer everyone to President Uchtdorf's message in the June Ensign. I was thinking about what Julia had written when I read his message and several things stuck out to me. Mostly, and most importantly, this:
"There is a way to rise above the turbulence of everyday life . . .. You must create lift" by cultivating your own personal righteousness.
He was speaking mainly of prayer but all personal righteousness, including scripture study, helps create the lift that we need.
A few other thoughts I liked from his talk that don't relate to Ju's question include: "Our prayers should spring from our deepest yearning to be one with our Father in Heaven."
And, "The sincere prayer of the righteous heart opens to any individual the door to divine wisdom and strength in that for which he righteously seeks." Like more patience with my children? A greater ability to feel joy? Increased unity with my spouse?
My favorite part of the whole message though was the scripture he quoted, D&C 46:30: "He that asketh in the Spirit asketh according to the will of God; wherefore, it is done even as he asketh."
