What is the Pupose of Temple Sealing?

OBJECT LESSON ON TEMPLE SEALING:

Have several paper clips lying on the table.  With a magnet, pick one up.  Touch that paper clip to another paper clip and they should stick together.  You will probably be able to pick up three paper clips touching each other in a line until the magnetism is too weak to pick up another and it will drop.  This symbolizes family members (paper clips) and earthlife (magnet).  While we are here on earth, we are connected, father to son to grandson, but it is not permanent.  Eventually one family member dies and the link is broken.  The bond is not strong enough.  It is simply "till death do you part."

Then pick up the paper clips again, but this time link them together instead of relying just upon the magnet.  This symbolizes our temple covenants.  It doesn't matter whether we have the magnet anymore.  The bond cannot be broken, and it can be linked back generations and forward generations with no fear of a break.

I saw this idea and felt it a great way to explain the sealing ordinance in the temple.  In the temple we are sealed as families to our spouses.  Each of the children are also sealed to the parents.  This allows multiple generations to be sealed together as families. 

As we do family history work, we seal a sets of families (parents and children) together, creating links, like the paperclips that span generations.  We are able to connect grandparents and great grandparents to their grand children and great grand children.  Its wonderful to think that in the eternities we can live together as families, bound and sealed together forever, generation upon generation.

As my husband is not a member of the LDS faith, I have not had the opportunity to be sealed to my family, or to my children.  Our link at the moment is broken.  There is authority that can be preformed to seal our family for time and all eternity, only until death do us part.  One day things might change, and that link might be able to be connected, but if not, my children still have the opportunity to be sealed for all eternity to their own spouses as they come of age to marry and as well as to their own children.
