I wish you as Latter-day Saints, when you go home, would sit down and study rationally, and see what principle there is that will be developed in building up the kingdom of God, according to the light of inspiration; you can read in the good book, and according to all that has ever shone around you, or in your own heart; and if you can find a principle in building up that kingdom, you will find one that, in the first place, is to be developed in the circle of every human being that hopes to be associated in building it up. ”
