In the context of a power struggle within a couple, the Bible teaches that marriage is a partnership based on love, mutual respect, and submission to one another. In Ephesians 5:21-33, it emphasizes the importance of wives submitting to their husbands as the head of the household, just as the church submits to Christ. However, this submission is not about dominating or controlling one another, but rather about sacrificial love. Husbands are called to love their wives as Christ loved the church, giving themselves up for her. Therefore, a healthy power dynamic is one where both partners value and uplift each other, seeking to serve and support one another in a harmonious and loving relationship.
