The first verse above quoted has the same meaning as this last quotation. The second refers to the events of his life of which they were witnesses. He foresaw that the record of those events would be read by future generations, and compared with later experiments. He had left the power to heal as a heritage to all who should come after him, possessing the requisite faith; and he knew that the testimony of his disciples concerning the works that he had performed would be compared with later exhibitions of the same power. He foresaw that the "Spirit of truth" would eventually discover the laws pertaining to his doctrines and his works, and that a comparison of the testimony of his followers with the discoveries of science would demonstrate to the world the essential truth of his history and of his spiritual philosophy. I shall now briefly point out a few of the more salient features of the history of Jesus which bear upon the subject under consideration, and shall undertake to show, first, how the discoveries of modern science confirm the accounts of his physical manifestations; and secondly, how they confirm the essential features of his spiritual philosophy. The prominent feature of his physical manifestations consisted in healing the sick; and in the discussion of the first division of the subject I shall confine myself to the consideration of that part of his career. The first proposition bearing upon the subject is, that Jesus Christ was the first who correctly formulated the exact conditions necessary and indispensable to the exercise of the power to heal the sick by psychic methods. The second proposition is, that the conditions which he declared to be necessary to enable him to exercise that power are the same conditions which are indispensable to-day. These propositions will be considered together. The condition which he declared to be essential, not only in the patient, but in the healer, is embraced in the one word _faith_. 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 him dominion over all 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 hill-tops of Palestine he gave to mankind the key to health and to heaven, and earned the title of Saviour of the World.
