Hence the necessity of the dispensation of the Holy Spirit. Hence the various directions, which are given in the Scriptures not to grieve, and not to quench the Holy Spirit. Hence the declaration, that Christians are the temple of the Holy Ghost. And accordingly it is a great truth, though but imperfectly understood and estimated, that he, who, moves and acts in religious things without the attendant operation and grace of the Holy Ghost, cannot be spiritually wise, and is not in the way to be spiritually benefited.
