How long does a woman's hair have to be?
"Does not even nature itself teach you that if a man has long hair, it is a dishonor to him? But if a woman has long hair, it is a glory to her; for her hair is given to her for a covering" (I Corinthians 11:14-15).
"Long" is a relative term. God is not dictating a specific length of hair. Instead, He is insisting that the prevailing hair styles among men is to be shorter than the prevailing hair styles among women. Since the beginning of time, God expected a distinction to be made between the sexes. For example, in the law of Moses, God said "A woman must not wear men's clothing, nor a man wear women's clothing, for the Lord your God detests anyone who does this." (Deuteronomy 22:5) Other than articles of clothing, the relative length of hair is the most distinctive difference between men and women. If the hair on a woman leaves you wondering whether she might really be a he, then the hair is too short.
Satan, the old enemy of God, has filled people's minds with the idea that everyone should look and act the same. Somehow he has convinced people that men and women looking different is wrong. Why can't people, and especially Christians, be content to follow the teaching of the Bible, custom, and common sense, and let men be men and look like men and women be women and look like women?
