President Boyd K. Packer of the Quorum of the Twelve taught us about how temple work and family history can bless our life,

“No work is more of a protection to this Church than temple work and the family history research that supports it. No work is more spiritually refining. No work we do gives us more power. No work requires a higher standard of righteousness.”
