Marriage is the foundry for social order, the fountain of virtue, and the foundation for eternal exaltation. Marriage has been divinely designated as an eternal and everlasting covenant. Marriage is sanctified when it is cherished and honored in holiness. That union is not merely between husband and wife; it embraces a partnership with God. “Husband and wife have a solemn responsibility to love and care for each other.” Children born of that marital union are “an heritage of the Lord.” Marriage is but the beginning bud of family life; parenthood is its flower. And that bouquet becomes even more beautiful when graced with grandchildren. Families may become as eternal as the kingdom of God itself.
Russell M. Nelson
