Well, it's quite simple, really. We, as
Latter-Day Saints, perform baptisms for the dead, just as they did in New
Testament times. The apostle, Paul said, "Else what shall they do which are baptized
for the dead, if the dead rise not at all? Why are they then baptized for the
dead?" (1 Corinthians 15:29). Paul was testifying of the resurrection,
saying if there wasn't a resurrection, they wouldn't be baptizing for the dead.
But, they WERE baptizing for the dead and there IS a
resurrection.
We,
likewise, perform this same ordinance in our days in LDS temples. Now some
might say, 'you mean, you actually baptize dead bodies?' Of course not! Those
who have passed on are baptized by proxy through us.
Now others might say this,
'why would you force that upon someone else if you don't know he/she really
wants that?' Well, nothing is forced upon them. The individual may CHOOSE to
accept or reject the ordinance performed for him or her. Our Heavenly Father would
never force anyone into anything. He has given us all the precious gift of agency. But, we pray that all WILL accept this saving ordinance.
This
is a major reason Latter-Day Saints are interested in family history. We want
to find all of our ancestors who didn't have a chance to hear and learn the
restored gospel on earth—the true and full gospel that Jesus brought to the world.

Enter this door as if the floor within were gold;
And every wall of jewels all of wealth untold;
As if a choir in robes of fire were singing here;
Nor shout nor rush but hush … for God is here.
Is that not beautiful? The temple is
the one place on earth that is closest to heaven. How grateful I am for the
power it brings to my life!
