In the book of Ephesians, it teaches us about the importance of mutual respect, love, and communication within a marriage. Just like Christ loved the church, husbands are called to love their wives selflessly and sacrificially. Likewise, wives are instructed to submit to their husbands, not as a sign of inferiority, but as a way to show respect and create harmony in the marriage. By following these biblical principles, a couple can build a strong and loving relationship that is centered on God's teachings.
