Without the family, there is no plan; there is no reason for mortal life.

Parents, teachers, and leaders of youth need to teach the rising generation the doctrine of the family. It is essential to help them achieve eternal life (see Moses 1:39). They need to know that the theology of the family is based on the Creation, the Fall, and the Atonement. They need to understand the threats to the family so they will know what they are fighting against and can prepare. They need to understand clearly that the fulness of the gospel is realized in temple ordinances and covenants....“The Family: A Proclamation to the World” was written to reinforce that the family is central to the Creator’s plan. 

Without the family, there is no plan; there is no reason for mortal life.
