While we should certainly make a public profession of faith in Christ, our faith is authenicated in the sight of others by our works that back up our faith. If we have no good works to back up our faith, in the eyes of others our religion will be seen to have no impact, no power, and no force in our lives. However, if we properly exhibit a life filled with sacrifical good works, our faith and religion is proven to be pure and undefiled to our peers in our lives.
