Families - their importance
" . . . marriage between a man and a woman is ordained of God . . . the family is central to the Creator’s plan for the eternal destiny of His children.

"All human beings — male and female — are created in the image of God. Each is a beloved spirit son or daughter of heavenly parents, and, as such, each has
a divine nature and destiny. Gender is an essential characteristic of individual premortal, mortal, and eternal identity and purpose. ..." (Proclamation on the Family, 1995)
Members of The Church of Jesus Christ of Latter-day Saints view the family from an eternal perspective. For those who have the opportunity to enter into temple marriage in this mortal life, the potential blessings in the eternities are beyond our ability to imagine.

For those who would have been married in an LDS temple if they had been given the opportunity—they will receive that glory in God's own time in the next life.
"Our journey through life has periods of both good times and bad. . . . How we learn to adjust to the changes which come along depends on the foun- dation on which we build. The gospel of our Lord and Savior provides a sure and solid foundation . . . constructed piece by piece as we gain knowledge of the Lord’s eternal plan for His children. The Savior is the Master Teacher. We follow Him. . . .

"Many in our worried society understand that the disinteg- ration of the family will bring only sorrow and hopelessness into a troubled world. As members of the Church, we have the responsibility to preserve and protect the family as the basic unit of society and eternity. The prophets have warned and forewarned about the inevitable and destructive consequence of a deterioration of family values." (Elder Perry)
