"Take the good out of the murky"

It's not good to care so much about our outward selves, that we forget our inward selves. Then again its not good to not care about our outward selves such that we don't even respect our body or appreciate the beauty that we are part of God's creation. The answer is not black and white. Wearing bummy clothes and never combing our hair is not what Peter's asking. He's asking that we remember where our TRUE beauty lies; he's asking us to examine ourselves and ask the tough questions 'Does outward beauty matter more than inward beauty to us?', 'Are we putting more effort inwards than we do outwards?'. Really it all boils down to one question, 'Where do our hearts lie? In ourselves or in God?'

Therefore its good to love our outward selves and appreciate the fact that we are God's creation, while seeking and searching to conform our inward selves to the beauty of Christ-likeness through the transforming power of the Holy Spirit.

"Your beauty should not come from outward adornment, such as braided hair and the wearing of gold jewelry and fine clothes. Instead, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God's sight." - 1 Peter 3:3-4
