IV. Others, not elected, although they may be called by the ministry of the Word, and may have some common operations of the Spirit, yet they never truly come to Christ, and therefore can not be saved: much less can men, not professing the Christian religion, be saved in any other way whatsoever, be they never so diligent to frame their lives according to the light of nature, and the law of that religion they do profess; and to assert and maintain that they may is without warrant of the Word of God.
