The hair under discussion in 1 Corinthians 11 is the hair on a person's head. Shaving your legs is not related to this issue. As for arching your eyebrows, that is a different matter. Are you really so unhappy with the way God designed your face that you feel you must take matters into your own hands and alter it. We can understanding plucking out hairs that grow where hair normally doesn't grow, but to alter the basic shape and structure of your eyebrows seems to us to be an expression of contempt toward our Creator. We encourage you to learn to be content in your own skin; that is, with the way God made you. You are welcome to make the most of what you have, but why try to make it different from what God has made. You are your most beautiful to the Lord when you present yourself to Him as He made you. Paul said, 'Godliness with contentment is great gain!'
