Exaltation or Eternal Life is a belief among members of The Church of Jesus Christ of Latter-day Saints that mankind can return to live in God's presence and continue as families. Exaltation is believed to be what God desires for all humankind. The Church teaches that through exaltation believers may become joint-heirs with Jesus Christ as stated in Romans 8:12 and Revelation 21:7. The objective of adherents is to strive for purity and righteousness and to become one with Jesus as Jesus is one with the Father. A verse in the canonized scripture, Doctrine and Covenants, states that those who are exalted will become gods, and a 1925 statement from the church's highest governing body said that "All men and women are in the similitude of the universal Father and Mother... capable, by experience through ages and aeons, of evolving into a God."
