God's design for family and marriage gives our relationship a beautiful and meaningful purpose and accomplishes His plans for the world. In scripture there is a providential dimension to marriage; it is to be a permanent and exclusive relationship, but also to be inclusive in the sense that it includes every part of the husband and wife's lives: their spirits, minds, hearts, and bodies. When couples are united as one, and live in this kind of unity, they reflect God's purpose for marriage.
