"When Jesus gave His disciples a new commandment to 'love one another; as I have loved you,' (John 13:34), He gave to them the grand key to happiness in this life and glory in the next.
"Love is the greatest of all the commandments--all others hang upon it. It is our focus as followers of the living Christ. It is the one trait that, if developed, will most improve our lives."
(Joseph B. Wirthlin, "The Great Commandment," Ensign, Nov. 2007, 30-31)
