Brigham Young
There is a great difference in the individual capacity of people. Some can receive much more than others can: hence we read of different degrees of glory. How many kingdoms glory of there are, I know not; and how many degrees of glory there are in these kingdoms, I know not; but there are multitudes of them. Paul speaks of three, Joseph Smith and Sidney Rigdon saw three, and multitudes more have we seen by the Spirit of revelation, according to the capacity of our understandings. Can we so live and direct ourselves as to receive glory, immortality, and eternal lives? We can. Then love not the world, nor the things of the world. Desire not that which is not for us, but desire only that which God has ordained for our benefit and advancement in the science of eternal life; then can we advance with accelerated speed in the things of God.
JD 9:107
Brigham Young
The kingdoms that God has prepared are innumerable. Each and every intelligent being will be judged according to the deeds done in the body, according to his works, faith, desires, and honesty or dishonesty before God; every trait of his character will receive its just merit or demerit, and he will be judged according to the law of heaven as revealed; and God has prepared places suited to every class. The Savior said to his disciples—“In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.” How many kingdoms there are has not been told to us: they are innumerable. The disciples of Jesus were to dwell with him. Where will the rest go? Into kingdoms prepared for them, where they will live and endure.
