How do we know husbands should love their wives as Christ loved the church?

In Ephesians 5:25, Paul commands husbands to love their wives just as Christ loved the church, emphasizing a love that sacrifices for the benefit of the spouse. Christ's love is demonstrated through His actions—He gave of Himself completely for the church. This establishes a standard for husbands to love their wives in a manner that reflects Christ’s care, protection, and commitment, which is foundational to a healthy marriage. This theological and marital framework guides husbands to ensure their wives feel loved and supported.
