Now the question is, how can we keep oil in our lamps? By keeping the commandments of God, remembering our prayers, do as we are told by the revelations of Jesus Christ, and otherwise assisting in building up Zion. When we are laboring for the kingdom of God, we will have oil in our lamps, our light will shine and we will feel the testimony of the spirit of God. On the other hand, if we set our hearts upon the things of the world and seek for the honors of men, we shall walk in the dark and not in the light.
– Wilford Woodruff, 1/9/1881
