(1) Most of the duties naturally discerned by the conscience from the known relations of life are brought into more distinct and definite view by Christian revelation and experience. The natural discernment is often unclear, uncertain, partial, and faulty. The blindness, mistakes and misgivings of the moral sense form a large and perplexing chapter in the story of non-Christian morality. It has often led to doubt whether there is such a thing as a fixed, sure, immutable morality. A remedy for this has been needed. By its immense number of specific _precepts_ for particular relations and circumstances, revelation gives correctness, minuteness, and fulness of application to the general principles of duty asserted by the moral sense. In manifold cases the conscience would be in the dark, or have only obscure or partial view, without the instruction and guidance thus supplied. Scarcely a situation or emergency in life can be named for which precept and counsel have not been given. When the sun rises the eye sees not only farther, but more minutely and with more certainty. Myriads of objects and relations before unseen flash into view. So by the light of the Scriptures, more of duty is known and better known. By common consent, even among skeptics as to the Christian religion, the ethical precepts of Christianity, in their purity and elevation, in their quickening directness and radical thoroughness, in their explicitness and universality, form an aggregate moral directory unapproached by the best codes of pagan sages or human philosophies, and add a grand aid to the moral judgments. ==Human Relations.==
