Marriage is God's idea. He created Adam with a need for a wife (Genesis 2:18). Unless called to be single, all men have this need. Marriage fulfills and completes each person.
Together, husband and wife have the capacity to demonstrate to the world the relationship between Christ and the Church. Can there be a higher calling? The husband loves the wife as Christ loves the church and the wife respects her husband as the church respects Christ (Ephesians 5:21-33). God therefore is glorified through the marriage relationship.
In most cases, it is also God's plan for a husband and wife to have children. Parents are given the primary responsibility to train their children in having a relationship with God (Deuteronomy 6:1-8; Ephesians 6:1-4).
As married adults are taught how to know God, walk with Him, and obey Him, they will in turn live lives that are full and meaningful. They will bring glory to God because they are satisfied in Him. Our goal then is to equip husbands, wives, and parents to fulfill their God-given assignments.
