1 Peter 3:3-5 says: "Don’t be concerned about the outward beauty of fancy hairstyles, expensive jewelry, or beautiful clothes. 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."
These Bible verses basically mean that beauty is not the outside, but it's on the inside. Beauty is how you think and how you act. It's about having a gentle and quiet spirit.
These are the things that are precious to God.
So, why put so much work on your outside?
Why not work on your inner-beauty?
