We are to fear Him: that is, in other words, we are to cherish an awful sense of His infinite grandeur and excellence, corresponding to the revelation He has made of these in His works and Word, inducing a conviction that His favor is the greatest of all blessings, and His disapprobation (disapproval) the greatest of all evils, and manifesting itself in leading us practically to seek His favor as the chief good we can enjoy, and avoid His disapprobation as the most tremendous evil we can be subjected to. Such is the fear which the Christian man ought to cherish and manifest towards God.
John Brown
