The need of larger knowledge, than that furnished by simply naturalistic ethics, for the perfection of moral life, has everywhere been evident. The debasement of moral thought and the worse debasement of moral life frequently found among peoples outside of the atmosphere illuminated by Christian truth, is sad proof how crying this need of right knowledge may become. The strife of conflicting opinions as to the root and validity of moral principles, even among many in Christendom who look at the subject with faces averted from Christianity, is perpetual remembrancer of the room for more and better information. And the perplexing phenomenon of wide diversity of moral judgments in daily life, to which we have had occasion several times already to refer, resulting from the different degrees of correctness with which the relations of life are understood and interpreted, enforces the same truth. The moral power is educable. It sees its objects in the light, not in darkness, nor fully in dawn. It acts best when flooded with the fullest knowledge. Men can discern duty accurately and fully only when they comprehend all their relations to God above them, their fellow-men around them, their destiny before them, and the significance and moral demand of these relations. From the high origin of their nature, "in the image of God," they may carry some impress of the moral law from God in their hearts, in the inner order of insight and spiritual vision, and in measure "read God's thoughts after Him" about love and justice and truth and other essential virtues. But this rational reading of duty from the law of right within them and from the moral constitution about them, is grandly helped when revelation throws its illumination on the nature and relations of men, the meaning of life and the reach of its responsibilities. Whatever has been the short-coming of Christianity's professors in exemplifying its moral teaching, the history of its work is full proof of its containing the best ethical direction and power the earth has yet seen. In individuals and communities in which its teachings have been worthily turned into character and life, it presents an inspiring suggestion of what it is capable of doing for human exaltation when its instruction is truly followed. It is the completing factor for moral guidance, and the scientific view is false to itself when it fails to include the teachings and the phenomena of the Christian consciousness and life. Since Christianity has come and given the world its highest civilizations and elevations, its grandest progress in philosophy, science, art, literature, invention, enterprise and prosperity, all the purest and most beautiful amenities of life, and is still leading the best nations onward and upward, it is surely worse than idle to think of forcing ethical science back to a pagan or merely naturalistic standpoint. This would ignore the greatest moral phenomenon of history and the most impressive facts in
