Don't be concerned about the outward beauty that depends on fancy hairstyles, expensive jewelry, or beautiful clothes.
You should be known for the beauty that comes from within, the unfading beauty of a gentle and quiet spirit, which is so precious to God.
That is the way the holy women of old made themselves beautiful. They trusted God and accepted the authority of their husbands.
For instance, Sarah obeyed her husband, Abraham, when she called him her master. You are her daughters when you do what is right without fear of what your husbands might do.
In the same way, you husbands must give honor to your wives. Treat her with understanding as you live together. She may be weaker than you are, but she is your equal partner in God's gift of new life. If you don't treat her as you should, your prayers will not be heard.
Finally, all of you should be of one mind, full of sympathy toward each other, loving one another with tender hearts and humble minds.
Don't repay evil for evil. Don't retaliate when people say unkind things about you. Instead, pay them back with a blessing. That is what God wants you to do, and he will bless you for it.
For the Scriptures say, "If you want a happy life and good days, keep your tongue from speaking evil, and keep your lips from telling lies.
Turn away from evil and do good. Work hard at living in peace with others.
The eyes of the Lord watch over those who do right, and his ears are open to their prayers. But the Lord turns his face against those who do evil."
