Brigham Young
How many of the youth of our land are entitled to all the blessings of the kingdom of Heaven, without first receiving the law of adoption? When a man and woman have received their endowments and sealings, and then had children born to them afterwards, those children are legal heirs to the kingdom and to all its blessings and promises, and they are the only ones that are on this earth. Where is not a young man in our community who would not be willing to travel from here to England to be married right, if he understood things as they are; there is not a young woman in our community, who loves the gospel and wishes its blessings, that would be married in any other way; they would live unmarried until they could be married as they should be, if they lived until they were as old as Sarah before she had Isaac born to her. Many of our brethren have married off their children without taking this into consideration, and thinking it a matter of little of importance. I wish we all understood this in the light in which heaven understands it (Journal of Discourses, volume 11, 1 July 1865).

You [missionaries] go home and find a person that will stimulate you, one that will keep you on your toes, that will make you be bigger than you are—never anyone that will let you relax. I would never be in the Council of the Twelve today if I had married some of the girls that I have known. Sister Kimball kept me growing and never let me be satisfied with mediocrity. . . .
Go all over the Church if you need to, to find the girl that is better than you are (The Teachings of Spencer W. Kimball, p. 303).
