Temples existed throughout Biblical times. These buildings were considered the house of the Lord (see 2 Chronicles 2:1-5). Latter-day Saint temples are likewise considered houses of the Lord by Church members. To Latter-day Saints, temples are sacred buildings in which they are taught about the central role of Christ in God’s plan of salvation and their personal relationship with God. In temples, members of the Church make covenants with God to live a virtuous and faithful life. They also offer sacraments on behalf of their deceased ancestors. Temples are also used to perform marriage ceremonies that promise the faithful eternal life with their families. For members of the Church, family is of central importance.
