Still it is one of the most hopeful features of present-day Christianity that men are becoming sensible that they are not mere individuals, but are members of a society; and that they must bear the shame of the existing condition of things in society. Intelligent Christian men now feel that the saving of their own souls is not enough, and that they cannot with complacency rest satisfied with their own happy condition and prospects if the society to which they belong is in a state of degradation and misery. It is by the growth of this sympathetic shame that reformation on a great scale will be brought about. It is by men learning to see in all misery and vice their own share of guilt that society will gradually be leavened. To those who cannot own their connection with their fellow-men in any such sense, to those who are quite satisfied if they themselves are comfortable, I do not know what can be said. They break themselves off from the social body, and accept the fate of the amputated limb.
"Again therefore Jesus spake unto them, saying, I am the light of the world: he that followeth Me shall not walk in the darkness, but shall have the light of life. The Pharisees therefore said unto Him, Thou bearest witness of Thyself; Thy witness is not true. Jesus answered and said unto them, Even if I bear witness of Myself, My witness is true; for I know whence I came, and whither I go; but ye know not whence I come, or whither I go. Ye judge after the flesh; I judge no man. Yea and if I judge, My judgement is true; for I am not alone, but I and the Father that sent Me. Yea and in your law it is written, that the witness of two men is true. I am He that beareth witness of Myself, and the Father that sent Me beareth witness of Me. They said therefore unto Him Where is Thy Father? Jesus answered, Ye know neither Me, nor My Father: if ye knew Me, ye would know My Father also."--JOHN viii. 12-19.
At the Feast of Tabernacles Jesus, who knew that He was sent to confer upon men the realities which had been symbolised and promised in all religious rites, proclaimed that He was the fountain of life (vii. 37); and thus responded to the unuttered prayer of those who looked with some weariness at the old routine of drawing water in remembrance of the provision God had made for their fathers in the desert. Another feature of the same Feast leads Him now to declare a further characteristic of His person. In commemoration of the Pillar of Fire that led their fathers in the trackless desert, the people lit large lamps round the Temple, and gave themselves up to dancing and revelry. But this, too, was no doubt felt to be for the superficial souls that can live upon rites and symbols, and do not seek to lay bare their inmost being to the very touch of eternal reality. Not merely the cynic would smile as venerable men joined in the lamp-light dance, but possibly even the grave and pious onlooker, looking back on his own mistakes in life, and conscious of the blind way in which he was still blundering on, stood wondering where the true Guide of Israel, the real Light of human life was to be found. In sympathy with all such longing after truth and clear vision Jesus cries, "I am the light of the world; he that followeth Me shall not walk in darkness, but shall have the light of life."
His words must be interpreted by their reference to the light which was then being celebrated. Of that light we read that "the Lord went before them by day in a pillar of cloud, to lead them the way, and by night in a pillar of fire, to give them light." This was a customary mode of directing the movements of large bodies of men, whether caravans or armies. In the case of an army a tall pole was erected in front of the chief's tent, and from it a basket of fire was suspended, so that the glare of it was visible by night, and its smoke by day. The head of a marching column could thus be descried from a great distance, especially in wide level tracts with little or no vegetation and few inequalities of surface to interrupt the view. The distinctive peculiarity of the Israelitish march was that Jehovah was in the fire, and that He alone controlled its movements, and thereby the movements of the camp. When the pillar of cloud left its place and advanced the tents were struck, lest they should be separated, from Jehovah and be found unfaithful to Him. During the whole course of their sojourn in the wilderness their movements were thus controlled and ordered. The beacon-fire that led them was unaffected by atmospheric influences. Dispelled by no gales, and evaporated by no fiercest heat of the Eastern sun, it hovered in the van of the host as the guiding angel of the Lord. The guidance it gave was uninterrupted and unerring; it was never mistaken for an ordinary cloud, never so altered its shape as to become unrecognisable. And each night the flame shot up, and assured the people they might rest in peace.
