I wholeheartedly believe in this. Those who love us on the other side of the veil must be anxiously engaged in work for us. Joseph Smith taught that they cannot be saved without us, but we also cannot be saved without them.

I've often wondered if the names we write down in the temple become the names those on the other side pick up when they go to do work for the living. I hope I never become too cynical or to hardened by the reality of life to see tender mercies coming from the other side of the veil. It might not always be the protection you were hoping for, but I believe a form of protection always comes.
