President Kimball tells a personal experience he had in one of his many stays at the hospital:
"In the hospital one day I was wheeled out of the operating room by an attendant who stumbled, and there issued from his angry lips vicious cursing with a combination of the names of the Savior. Even half-conscious, I recoiled and implored: 'Please! Please! That is my Lord whose names you revile.'
"There was a deathly silence, then a subdued voice whispered, 'I am sorry.' He had forgotten for the moment that the Lord had forcefully commanded all his people, 'Thou shalt not take the name of the Lord thy God in vain' (Exodus 20:7.)"
President Kimball went on to relate that such language demonstrates many things about a person: that they do not have self-control, and that they do not demonstrate gratitude towards God.
