Believers in the church should not only set the example for the world to follow, but should also be clearly and distinctly different than everyone else. To be holy is not to be separated from sinful people or to be morally perfect, but to be whole and complete, like Jesus. When we realize this, we will spare ourselves endless toil and self-effort trying to become something we already are. Belief in our true identities begins a transformation that makes us into the image of God. Reflecting Jesus is how we demonstrate what it is to be the light in a spiritually dark world.
