Mark 12

 In answering a question from the Sadducees, the Savior declares this truth - 

"...Do ye not therefore err, because ye know not the scriptures, neither the power of God?

25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven."  (Mark 12:24–25)

It appears that the covenant of  "eternal marriage" must be performed in this life or estate, whether in person or by proxy, before the resurrection.  Where after all are resurrected there will be know left from this life to perform the ordinance.

With this logic would suggest that the Savior must have been married for time and all eternity during His life.
