Heber C. Kimball

"I am perfectly satisfied that my Father and my God is a cheerful, pleasant, lively, and good-natured Being. Why? Because I am cheerful, pleasant, lively, and good-natured when I have His Spirit. That is one reason why I know; and another is--the Lord said, through Joseph Smith, 'I delight in a glad heart and a cheerful countenance.' That arises from the perfection of His attributes; He is a jovial, lively person."
