I have been anxious to make these observations, because it seems to me that the passage of St. John's Gospel of which I am to speak to-day will be utterly obscure to us--nay, that the whole Gospel will be obscure--if we forget them. St. John can in nowise separate the idea of the Baptist from that of a witness concerning the Light, a messenger to declare the divine Word that in Him all men might believe. This he considers the fundamental, radical meaning of his mission, apart from which his baptism of repentance had no sense or purpose whatever. But to identify _a man_ as connected with this teaching--as the subject of it--this was the difficulty. To do this the Baptist needed a special, formal revelation, accompanied by an outward sign. The baptism of Jesus, and the visible token that the Spirit was given Him, are said to have been the assurance which was required. While he was without it, he was a preacher of the Word who was with God and was God. He was a preacher of a light of men. He was announcing, as the prophets of old had announced, that a day of the Lord was at hand; that there would be a manifestation of the light. Thenceforth he began to mingle his previous message with announcements concerning _the Word made flesh_. These announcements are not repeated as if they were parts of a continuous discourse, like his words to the crowds that had flocked to him from every part of Palestine. They come forth as if they were the effect of sudden intuitions--lightning flashes which must often have been followed by periods of dimness and darkness. John knew that a crisis was at hand which would try the hearts of all men. He knew that he was sent by God to speak to their hearts of Him, as being the same now that He had been in the days of their fathers. He knew that whatever good was awaiting his countrymen must come from a fuller revelation of God. This was the preparation, the only possible preparation in his own mind, for the recognition of Jesus as the Christ,--the only way in which he could prepare his countrymen for _such_ a Christ.
