In Mormonism, the concept of the eternal family is central to the plan of salvation. Through temple ordinances such as celestial marriage and sealing, families are believed to be bound together beyond death. Parents, children, and extended generations can remain united eternally if covenants are made and kept.
This teaching makes family relationships a core part of Mormon religious life. Faithful members strive for temple marriage and family sealing, since these ordinances are viewed as requirements for exaltation in the Celestial Kingdom. The idea of eternal families reinforces the importance of obedience, temple worship, and covenant keeping in everyday LDS practice.
