Ah, yes; the Forever Family® that they so famously tout!
Families can be together forever. To enjoy this blessing we must be married in the temple. When people are married outside the temple, the marriage ends when one of the partners dies. If we keep our covenants with the Lord, our families will be united eternally as husband, wife and children. Death cannot separate us (Gospel Principles, 2009 ed., p. 209).
Wanna bet!?
Romans 7 (nasb)
1 Or do you not know, brethren (for I am speaking to those who know the law), that the law has jurisdiction over a person as long as he lives?
2 For the married woman is bound by law to her husband while he is living; but if her husband dies, she is released from the law concerning the husband.
Matthew 22
23 That same day the Sadducees, who say there is no resurrection, came to him with a question.
24 Teacher, they said, Moses told us that if a man dies without having children, his brother must marry the widow and raise up offspring for him. 25 Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. 26 The same thing happened to the second and third brother, right on down to the seventh. 27 Finally, the woman died. 28 Now then, at the resurrection, whose wife will she be of the seven, since all of them were married to her?
29 Jesus replied, You are in error because you do not know the Scriptures or the power of God. 30 At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven.
