God a Cheerful Being?

President Heber C. Kimball said: "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" (D&C 59:15). That arises from the perfection of His attributes; He is a jovial, lively person, and a beautiful man.

(Journal of Discourses, 4:222.)

Kinda gives one pause to think of a Cheerful God. I, at least, often think of God in terms of grave seriousness. I mean, this is serious business! (Life, the Plan, etc.).

So, in terms of "Be ye therefore perfect, even as your Father which is in heaven is perfect", I guess that means we should strive to be cheerful, pleasant, lively, and good-natured.
