[Heber C. Kimball]
"I have noticed that a man who has but one wife, and is inclined to that doctrine, soon begins to wither and dry up, while a man who goes into plurality [of wives] looks fresh, young, and sprightly. Why is this? Because God loves that man, and because he honors his word. Some of you may not believe this, but I not only believe it but I also know it. For a man of God to be confined to one woman is small business. I do not know what we would do if we had only one wife apiece."
