The impotence of the conscience before the moral task has always been an impressive fact. The perception of duty has lacked efficiency for the enforcement of duty. Vision of the right largely fails to secure conformity to it. Even the clearest intellectual discriminations and illuminations of the moral law have often been only as the play of cold light, almost like the aurora of the north quickening nothing into life or fruitage. Here is found the chief point of failure in natural ethics. It has power to dictate, but not to move. It wants an efficient dynamic for overcoming the moral evil that has established itself in human nature and life--evil so positive and dominant as to justify an apostle in representing the better ethical will as disabled: "Ye cannot do the things that ye would." Prof. Flint says: "The wisdom of the heathen world, at its very best, was utterly inadequate to the accomplishment of such a task as creating a due abhorrence of sin, controlling the passions, purifying the heart, and ennobling the conduct."[67] The aim of Christianity is supremely practical. It seeks to save from sin and bring to righteousness. It wastes no effort for simply speculative results. It comes "not in word only, but in power." Besides its service to morals in confirming and extending our needed knowledge of duty, its greatest ethical service is in supplying the needed dynamic or efficacious force for the realization of the holy life. How does it enable the moral task? ==Completion of the Ethical View.== =1.= In some degree by the completion of the ethical view itself. The clearer light is forceful and efficacious for a better realization of the moral task. "Knowledge is power," especially knowledge which throws into view the most impressive realities and relations, and appeals with the most cogent motives. By the strong illumination shed upon the general principles of right and virtue, by the definiteness and detail of the instruction and precepts for all situations in life, by the elevation of view in which the moral horizon is widened and extended, so as to show a living brotherhood of every man with every other round the world and a range of moral interests and responsibilities interminable as eternity, by the emphasis with which men are made amenable to God for all moral duties, even those to men, thus vivifying the whole moral consciousness with a sense of a close, unescapable accountability to God the conscience is better enlightened and quickened for its task, strengthened by the fullest certainty and under the vigor of a new inspiration. It has more light for direction; it bears grander motive forces before the will. ==Assurance of Success.==
