Our source of knowledge is light and truth. It is the word of God in the beautiful framework of continuing revelation. Truth and light must indeed be received before there can be a dissemination of it. The Savior provided living water to the spiritually deprived. We should strive for that capability also. Ours is not the role of the book vendor who merely carries out an exchange. As we convey properly, we must give of ourselves. Truth travels best on the wings of personal testimony and individual worthiness. – Robert L. Simpson, “These Four Things,” Ensign (CR) May 1976
