“You thus learn some of the first principles of the Gospel, about which so much hath been said. When you climb a ladder, you must begin at the bottom, and ascend step by step, until you arrive at the top; and so it is with the principles of the Gospel–you must begin with the first, and go on until you learn all the principles of exaltation. But it will be a great while after you have passed through the veil before you will have learned them all. It is not all to be comprehended in this world; it will be a great work to learn our salvation and exaltation even beyond the grave.”
