You: What you're saying is false. Do you care?
My comment here didn't originate with me...I simply am taking a "cue" from two Lds past "prophets":
(1) Joseph F. Smith, Joseph Smith's nephew
(2) and Joseph Fielding Smith, Joseph Smith's great nephew
Here's what they had to say 'bout the import of marriage from a Mormon perspective:
...this doctrine of the eternal union of the husband and wife and of plural marriage, is one of the most important doctrines ever revealed to man in any age of the world. Without it man would come to a full stop; without it we never could be exalted to associate with and become gods neither could we attain to the power of eternal increase... (Joseph F. Smith, Journal of Discourses, Vol. 21, pp. 9-10)
"So if you want to enter into exaltation and become as God, that is a son of God or a daughter of God, and receive a fulness of the kingdom, then you have got to abide in his law-not merely the law of marriage but all that pertains to the new and everlasting covenant... (Joseph Fielding Smith, Doctrines of Salvation, Vol. II, p. 63)
The latter citation comes from a book published by the Mormon Church itself:
Deseret Book.com: Doctrines of Salvation
So are you telling us, SP, that these "prophets'" teachings are "false?"

Here's some related material:
In the Mormon view of heaven, ONLY those entering into Mormon "covenants" and obeying fully Mormon laws get to live forever in God's presence:
* Eternal life is living with Heavenly Father and Jesus Christ in the celestial kingdom. This blessing--which is also called exaltation--comes only to those who keep the commandments and make the necessary covenants (Source: Preparing for Exaltation Teacher's Manual, p. 4, 1998)
Obviously one of the "covenants" Mormons are expected to enter into is marriage...and not only "marriage," but marriage "for eternity" in the Mormon temple...so says the Mormon Encylopedia: “’Eternal life’ is a higher state than immortality alone and means to live forever in a resurrected condition in the presence of God, and to become like God…Eternal life is exaltation into the type and quality of life that God lives. Receiving eternal life is conditional, predicated upon obedience to the fullness of gospel law and ordinances (D&C 29:43-44; 130:20-21). It REQUIRES voluntary obedience to all of the ordinances and principles of the gospel…continuing through…the covenants of the Endowment and MARRIAGE IN THE TEMPLE…” (Encyclopedia of Mormonism, 2:677-678)
