George Q. Cannon teaches: "There are different degrees of glory. Some attain to a more exalted glory. They must help those who are lower to rise up to their plane. Then there is another degree below them, and they must labor to lift those who are lower than they... progressing from one degree of glory to another, without end, because there is no end to eternity."
