What does the Bible say about marriage and Christ's relationship with the church?

In Deuteronomy 24:5, the law describes how a man, after taking a new wife, should not go out to war but should cheer up his bride. This is interpreted as a reflection of Christ, who chooses His bride and provides unbroken communion with her. Just as a husband is to make his wife glad, Christ has espoused His church, ensuring she experiences His love and righteousness. This relationship is characterized by a sweet, eternal union where His desires become our desires, and we find joy in following Him.
