Fashion, style, and the look take over many people on a regular basis. We tend to communicate signals convincingly to other people by our look. Millions of dollars are spent each day around the world on this very matter.
I suppose there is value in how we look. Certain jobs and opportunities would not be available to us if our 'look' was wrong. I remember a business interviewer who swore by the socks men wore in their suits for work. He would simply say that if they missed these small details, then they weren't a high enough standard for the company.
What are we communicating? What do we intend to communicate by our look? Does it resemble the 'look' of Jesus?
1 Samuel 16:7 (NIV)
7 But the LORD said to Samuel, "Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things man looks at. Man looks at the outward appearance, but the LORD looks at the heart."
