The condition which Jesus of Nazareth, on various occasions during the three years of his ministry on earth, declared to be essential, in the mind of both healer and patient, is contained in the one word--FAITH. Can drugs suddenly cure leprosy? When the ten lepers were cleansed and one returned to give thanks in Oriental phrase, Jesus said to him: "Arise, go thy way; thy faith hath made thee whole." That was Christian Science. In his "Law of Psychic Phenomena" Hudson says: "That word, more than any other, expresses the whole law of human felicity and power in this world and of salvation in the world to come." It is that attribute of mind which elevates man above the level of the brute, and gives dominion over the physical world. It is the essential element of success in every field of human endeavor. It constitutes the power of the human soul. When Jesus of Nazareth proclaimed its potency from the hilltops of Palestine he gave to mankind the key to health and heaven, and earned the title of "Savior of the World." Whittier, grandest of mystic poets, saw the truth: "That healing gift He lends to them Who use it in His name; The power that filled his garment's hem Is evermore the same." Again, in a poem entitled "The Master," he wrote: "The healing of his seamless dress Is by our beds of pain; We touch Him in life's throng and press, And we are whole again." [Footnote: About 1868, the author of SCIENCE AND HEALTH healed Mr. Whittier with one visit, at his home in Amesbury, of incipient pulmonary consumption.--M.B. EDDY.] That Jesus operated in perfect harmony with natural law, not in defiance, suppression, or violation of it, we cannot doubt. The perfectly natural is the perfectly spiritual. Jesus enunciated and exemplified the principle; and, obviously, the conditions requisite in psychic healing to-day are the same as were necessary in apostolic times. We accept the statement of Hudson: "There was no law of nature violated or transcended. On the contrary, the whole transaction was in perfect obedience to the laws of nature. He understood the law perfectly, as no one before him understood it; and in the plentitude of his power he applied it where the greatest good could be accomplished." A careful reading of the accounts of his healings, in the light of modern science, shows that he observed, in his practice of mental therapeutics, the conditions of environment and harmonious influence that are essential to success. In the case of Jairus' daughter they are fully set forth. He kept the unbelievers away, "put them all out," and permitting only the father and mother, with his closest friends and followers, Peter, James, and John, in the chamber with him, and having thus the most perfect obtainable environment, he raised the daughter to life. "Not in blind caprice of will, Not in cunning sleight of skill, Not for show of power, was wrought Nature's marvel in Thy thought."
