Image is everything—or so the saying goes. We live in a world consumed with how things look rather than what they are. Often, the same is true of ourselves, when we worry about our appearance to others rather than our hearts, which guide our thoughts and deeds. Paul was aware of this tendency in people, so he encouraged the Ephesian believers to throw off the old self—the one stuck in darkness, callousness, impurity, and greed—and put on the new self—the one characterized by holiness and righteousness. This is how we begin to look like Christ's followers inside and out.
