"We are here to prepare to live, and to teach our children how to live after us; and to teach the world the same lesson if they will only receive it. We know that our spirits existed with the Father before we came here. We know that we are immortal as well as mortal beings, and that we have had to do with another world as well as this. We know that the world abounds with corruption; but it is our business to keep ourselves from it, and to progress in virtue, truth, integrity and holiness” (Teachings of Presidents of the Church: John Taylor, p. 187).
