In the Bible, so much of the marriage language about weddings, brides, and grooms is discussing the relationship between God and his people. In the Bible, in spite of humanity’s sin, turning away from God, the Lord is depicted as a faithful groom.
In the New Testament, the church is depicted as the bride and Christ is the groom. That’s part of the reason why our passage said “husbands love your wives as Christ loved the church and gave himself up for her.”
