How do we know that marriage reflects God's design?

God's design for marriage is firmly established in the Scriptures, beginning with His declaration in Genesis that it is not good for man to be alone (Genesis 2:18). This initiation of the marital relationship reflects God's intention for companionship, partnership, and support. Furthermore, the imagery used in Ephesians 5 portrays this union as a sacred mystery that mirrors Christ's sacrificial love for His church. The biblical narrative consistently underscores the purpose of marriage as not just a societal construct, but as an essential part of God's creative order, designed for intimacy, support, and the modeling of Christ-like love.
