O let us never forget; that the wonderful things contained in the divine law can neither be discovered nor relished by the “natural man,” whose powers of perception and enjoyment are limited in their range to the objects of time and sense. It is the divine Spirit alone who can lighten the darkness of our sinful state, and who can enable us to perceive the glory, the harmony, and moral loveliness which everywhere shine forth in the pages of revealed truth (John Morison).
