1 Peter 3:4-5 You should clothe yourselves instead with the beauty that comes from within, the unfading beauty of a gentle and quiet spirit, which is so precious to God.  This is how the holy women of old made themselves beautiful. They put their trust in God and accepted the authority of their husbands.
In the previous verse, Christian women are told to not worry about fancy hairstyles or clothing. Instead, they are to “clothe themselves with the beauty that comes from within.” Wives are to respect the authority of the husband. I don’t believe this is inequality. Instead, it’s that husbands and wives cannot be compared! We have two completely different roles.
