These, however, cannot of themselves produce a firm faith in Scripture until our heavenly Father manifest his presence in it, and thereby secure implicit reverence for it. Then only, therefore, does Scripture suffice to give a saving knowledge of God when its certainty is founded on the inward persuasion of the Holy Spirit. Still the human testimonies which go to confirm it will not be without effect, if they are used in subordination to that chief and highest proof, as secondary helps to our weakness.
