2 Samuel 6:14,21-22 NKJV
Then David danced before the LORD with all his might; and David was wearing a linen ephod. [21] So David said to Michal, "It was before the LORD, who chose me instead of your father and all his house, to appoint me ruler over the people of the LORD, over Israel. Therefore I will play music before the LORD. [22] And I will be even more undignified than this, and will be humble in my own sight. But as for the maidservants of whom you have spoken, by them I will be held in honor."
Dance before the Lord and don't be ashamed! Just like King David was not moved by his own wife's criticism for worshipping God don't be moved by others criticism of you! There will always be bitter people around but you don't have to be one of them. King David didn't care what others thought. It says he danced with all his might why? Because of the joy and thanksgiving he had toward the Lord! So go ahead and dance before the Lord with all your might!
