Speaking of the spirits of the dead Joseph F. Smith said, 'I  claim that we live in their presence, they see us, they are solicitous  for our welfare, they love us now more than ever...They see the  temptations and evils that beset us in life, and the proneness of mortal  beings to yield to temptation and to wrong doing; hence their  solicitude for us and their love for us and their desire for our well  being must be greater than that which we feel for ourselves..If we can  see, by the enlightening influence of the Spirit of God and through the  words that have been spoken by the holy prophets of God beyond the veil  that separates us from the spirit world, surely those who have passed  beyond can see more clearly through the veil back here to us than it is  possible for us to see to them from our sphere of action..we are not  separated from them..We cannot forget them; we do not cease to love  them; we always hold them in our hearts, in memory, and thus we are  associated and united to them by ties that we cannot dissolve, or free  ourselves from." (Gospel Doctrine, pp. 430-31)  
“So often we think of our responsibility to do something for those who have gone before. We need to understand that probably one of the most important beneofits of preserving our heritage is what it does for us today. If we want our problems to be solved, one of the surest ways of doing that is to search for our past, for therein we receive strength, guidance, and understanding. All of you here today are giving an added eternal dimension to your lives as you learn and study the past. We can receive strength and
help from those who have gone on before. To raise our families today, we need to do family research and genealogy.” -- Elder John H. Groberg
"To my mind, there isn't anything to great and so glorious in  this world as to labor for the salvation of the living and for the  redemption of the dead." 
-- Joseph F. Smith YWJ 23:130, January 1912 
"The work for our dead . . . l should not be neglected. We  should avail ourselves of those sacred and potent ordinances of the  gospel which have been revealed as essential to the happiness, salvation  and redemption of those who have lived in this world when they could  not learn the gospel and have died without the knowledge of it and are  not waiting for us; their children, who are living in an age when these,  ordinances can be performed, to do this work necessary for their  release from the prison-house. Through our efforts in their behalf their  chains of bondage will fall from them, and the darkness surrounding  them will clear away, that light may shine upon them and they shall hear  in thespirit world of the work that has been done for them by their  children here and will rejoice with you in your performance of these  duties. 
-- Joseph F. Smith CR, p. 6, October 1916
