We are taught from infancy how to wear masks. How to cover up our innermost being, our thoughts, and emotions. It is no surprise then that this tendency transfers into our dancing. But God wants more. He wants to use us as transparent vessels for His glory. Vessels that He can pour into and out of.

Matthew 5:15-17 (KJV)
 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
