Do you ever look at yourself in the mirror? Really look. Not just check your appearance. What does your face say about your outlook on life? Where are you going? What is written in it? Do you stop for introspection and ask yourself who you really are? When no one's around and it's just you and the mirror do you take a moment to reflect on what you really see in yourself?
I think this can be a useful exercise in gaining a visual representation of your emotional, mental, and physical state. We can get caught up in the busyness of life and just check appearances, make sure the exterior is in place and not pause to check out the interior. Next time you look into a mirror take a moment to reflect on how you look inside. Are you all hustle and bustle or calm and collected? Does God's peace sit beneath the exterior?
