We know that the sacrifice of Jesus' life on the cross of Calvary covers our sins. I am reminded that Jesus continues to cover us as we walk daily. Our skin is an apt analogy for this covering. We don't often think of our skin as a body organ, but it is. It covers our vulnerable inner body and protects it from infection, insulates from cold, cools when over heated, and gives us the capacity to touch and sense our outer world. Although our skin may appear to be something static...like a rug on a floor...nothing could be further from the truth. Every minute of every day we shed about 40,000 dead skin cells and replace them with new ones. Most of the outer layer of skin is constantly at work producing a fresh covering. Our middle skin layer contains the nerve endings that help us navigate our world and avoid dangerous extremes of temperature. Our inner skin layer provides insulation. The skin helps the body maintain a constant 98.6 degree temperature, regardless of our activity level or the weather around us.
All of this reminds me of the dynamic work of Christ who lives within us today. His covering is at work to shield us from the damage of sin. His presence provides us with the capability of touching our world and of sensing danger to our spiritual health. His spirit helps regulate our spiritual temperature and keep us on an even keel. Our inner person is able to navigate in a tough outer world because of His living cover.
Exodus 26:14 "You shall also make a covering of ram skins dyed red for the tent, and a covering of badger skins above that.
