In the Bible, the relationship between a couple is emphasized as a sacred and holy union, based on love, respect, and mutual submission. Ephesians 5:25-33 teaches husbands to love their wives as Christ loved the church, and wives to submit to their husbands. This passage highlights the importance of sacrificial love, mutual respect, and unity in marriage, with both partners honoring and serving each other in a God-honoring way. Ultimately, the Bible teaches that a strong and healthy marriage is grounded in faith, commitment, and a deep love for one another, mirroring the love that Christ has for His church.
