This is the eternal law of heaven: Amos 8:7
Surely the Lord God will do nothing, but he revealeth his secret unto his servants the prophets.

HMMMmmm...

I guess ol' Joseph shudda seen THIS coming...

JESUS: Hey Smith! Remember that boast you made about doing more than even I had done to hold the 'church' together?

JOSEPH SMITH: Where am I?

JESUS: Don't you remember? A few seconds ago you were in that jail.

JOSEPH SMITH: Oh; yeah; but where am I NOW?

JESUS: Don't you remember? Does bang - bang ring a bell?

JOSEPH SMITH: Oh; yeah - that crummy gun I had was about USELESS!

JESUS: I hope you left instructions on how to hold your church together.

JOSEPH SMITH: Dang! I knew there was SOMETHING I was forgetting!

JESUS: Looks like there's a power struggle going on down there.

JOSEPH SMITH: Yeah; there was always SOMEone who wanted the power that I held - especially over the LADIES - wink wink.

JESUS: No need to worry about that now; remember what my friend Matthew wrote down?

JOSEPH SMITH: This? “At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven” (Matthew 22:30)

JESUS: That's it.

JOSEPH SMITH: I thought that was mistranslated.

JESUS: Nah - it was right.

JOSEPH SMITH: Oh well; it was fun while it lasted. My buds will still get it on with the girls.

JESUS: Uh; I'm sorry; in just a few more years; your followers will cavein to the United States government and abandon the 'Everlasting Covenant' that you came up with.

JOSEPH SMITH: ME!? YOU are the one that told me to do that!

JESUS: Sorry; but you must have mistranslated what I told you. What part of Do NOT commit ADULTERY did you not understand?

JOSEPH SMITH: mumble....

JESUS: What did you say?

JOSEPH SMITH: Oh, nothing.

JESUS: Well; it was interesting talking to you; but now I must get back to perparing a place for those who believe in Me.

JOSEPH SMITH: Oh, yeah; the Celestial Kingdom.

JESUS: No...

JOSEPH SMITH: The Telestial one?

JESUS: Nope.

JOSEPH SMITH: SUREly not the TERRESTRIAL one!!

JESUS: Nope. Didn't you read that the mind of man had NOT conceived of it? Paul wrote it down in 1 Corinthians 2:9.

JOSEPH SMITH: I thought that was mistranslated.

JESUS: No; it wasn't.

JOSEPH SMITH: You SURE?

JESUS: Yes. Now I must be going: what did you say your name was again?

JOSEPH SMITH: Joseph Smith.

JESUS: Hmmmm. According to my Heavenly FAITHbook, you didn't sign in as one of my friends - sorry, I never knew you.

JOSEPH SMITH: But....

This is the eternal law of heaven:

The Doctrine and Covenants

Section 132

Revelation given through Joseph Smith the Prophet, at Nauvoo, Illinois, recorded 12 July 1843, relating to the new and everlasting covenant, including the eternity of the marriage covenant, and also the plurality of wives (see History of the Church, 5:501 - 7). Although the revelation was recorded in 1843, it is evident from the historical records that the doctrines and principles involved in this revelation had been known by the Prophet since 1831.

58 - 66, Laws governing the plurality of wives are set forth.
