What does the Bible say about the purpose of marriage?

The Bible portrays marriage as a profound mystery that reflects the relationship between Christ and the Church (Ephesians 5:32). It is established by God as an institution of divine significance, created before the fall of man. In Genesis 2:18-25, we see that God created Eve from Adam to be his companion, symbolizing a union designed for love, protection, and mutual support. As such, marriage holds a foundational place in God's creation, showcasing not just human relationships, but also illustrating the greater relationship of Christ's love for His people.
