A haughty look, a proud heart, and the plowing of the wicked are sin. (Proverbs 21:4)
The rolling of the eyes, the furling of the brow and curling of the lips is the language of a haughty look. They come from a proud heart and ought to be a strong symptom of the presence of sin in our lives. Body language and facial expressions reveal who we are more than the words we use and the actions we take. God's word is clear these things are sin and must be remedied. The cure comes through the realization that there is sin in our lives and the confession of that sin. For us to love righteously, we must die to sin. When sin shows its ugly face, change sin's expression and change the heart that brought it to the surface of who we are. Learn to read and understand your expressions. Do not hide behind a poker face, but change your hand by changing your heart. And put a smile on your face.
