Your beauty should not consist of outward things like elaborate hairstyles and the wearing of gold ornaments or fine clothes. Instead, it should consist of what is inside the heart with the imperishable quality of a gentle and quiet spirit, which is very valuable in God’s eyes. For in the past, the holy women who put their hope in God also beautified themselves in this way, submitting to their own husbands 1 Peter 3:3-5
1 Peter 3:3-4 (NCV) - It is not fancy hair, gold jewelry, or fine clothes that should make you beautiful. No, your beauty should come from within you—the beauty of a gentle and quiet spirit that will never be destroyed and is very precious to God.
