How do we know submission in marriage is a biblical concept?

The concept of submission in marriage is rooted in biblical teachings. In Colossians 3:18, wives are instructed to submit to their husbands as it is fitting in the Lord. This principle is illustrated through the relationship between Christ and His Church, where believers submit to Christ's authority. The importance lies not in an outdated cultural norm but in the divine order and harmony established by God in marital relationships. The obedience to this role is motivated by the love of Christ, showing that submission is a reflection of trust and alignment with God's design.
