There is no doubt whatever that Jesus created a revolution. Of course, some people would not have it, for it was too revolutionary for them. But others said: "Never man spake like this man" (John 7:46 - A.V.). And it is said of Him that "He taught them as having authority, and not as the scribes" (Mark 1:22). He brought in a complete revolution, but He did it by bringing Himself into view by what He said about Himself. He was always talking about Himself, and He is the only one in this world who has a right to do that. We are here today because He had a right to talk about Himself.
So the one business of disciples is to know Him, and to do what He called His disciples to do: "Take my yoke upon you, and learn of me" (Matthew 11:29). Jesus came to bring heavenly knowledge in His own person, and in His person we come into heavenly knowledge.
