"A lady came into our office the other day and asked to see me on a private matter. She informed me that she felt very badly, because her opportunities for getting a husband had not been favorable. … She wanted to know what her condition would be in the other life, if she did not succeed getting a husband in this life. I suppose this question arises in the hearts of our young people. … I desire to give a little explanation for the comfort and consolation of parties in this condition. There is no Latter-day Saint who dies after having lived a faithful life who will lose anything because of having failed to do certain things when opportunities were not furnished him or her. In other words, if a young man or a young woman has no opportunity of getting married, and they live faithful lives up to the time of their death, they will have all the blessings, exaltation and glory that any man or woman will have who had this opportunity and improved it. That is sure and positive. … People who have no opportunity of marrying in this life, if they die in the Lord, will have means furnished them by which they can secure all the blessings necessary for persons in the married condition. The Lord is merciful and kind, and He is not unjust. There is no injustice in Him; yet we could scarcely look upon it as being just when a woman or a man dies without having had the opportunity of marrying if it could not be remedied in the other life. There would be injustice in that, and we know that the Lord is not an unjust being. My sister Eliza R. Snow, I believe, was just as good a woman as any Latter-day Saint woman that ever lived, and she lived in an unmarried state until she was beyond the condition of raising a family. … I cannot for one moment imagine that she will lose a single thing on that account. It will be made up to her in the other life, and she will have just as great a kingdom as she would have had if she had had the opportunity in this life of raising a family." http://lds.org/manual/teachings-of-presidents-of-the-church-lorenzo-snow/chapter-9-sacred-family-relationships.p14,p15?lang=eng
Excerpt from Lorenzo Snow church manuelDon't get me wrong. In posting this it is in no way showing that I don't think I will marry in this life. Quite the opposite. I believe I will get married sometime in this life. I have a brightness of hope. Even still I find it marvelous that ALL opportunities to receive All blessings will be given to ALL the children of God. All that is required of us is to live worthy and do all we can to come close to the father. He is a just merciful and fantastic God. I take comfort in that knowledge of his goodness.
