It isn't natural. I remember a story I heard from a missionary that reminded me of similar things I have seen. A girl in one of his churches was campaigning to have women cover their arms fully because bare arms were worldly. The issue caused quite a controversy in their church as people debated whether they should mandate covered arms. The real sadness of stories like this is that they are so common.
Christians underestimate the reality of their own sin.
They get caught up in avoiding some external representation of sin, only to be ruined when the real thing overtakes them from within. So we've seen that when God saves us, he views us as perfect. He views us as having died and risen again to a new life. As a result, he comes to have fellowship with us. The Holy Spirit comes to live with us to change us.
