Religion might affect a person outward appearance but the Gospel changes a person from inside out.
A religious person wears a new set of clothing in keeping with the moral law and therefore looks different and even presentable to the world.
But a person whose conviction is changed is a new man, a man who is born again.
For true lasting change starts from the heart and overflows into godly living. And for such a man there’s no limitation of good works to the glory of God.
