A Division Arose Among the Jews

A division arose among the Jews – two camps, two inferences: John 10:19;

Camp 1:
▪︎ Jesus was crazy, or demon possessed, ruled by Satan – John 10:20;
  
Camp 2:
▪︎ His speech was clear and good.
▪︎ He was performing amazing signs and wonders – John 10:21;
  
Other Considerations:
▪︎ Jesus is considered by a large segment of the population to be a profoundly good teacher.
▪︎ If Camp 1 were true, He could not be considered good, but would rather be most evil.
▪︎ Consider too, that for the last 2,000+ years He has had the most profoundly positive effect on human civilization.

Conclusion: Jesus was who He said He was, the Expected One, the Messiah –

      19A division occurred again among the Jews because of these words. 20Many of them were saying, “He has a demon and is insane. Why do you listen to Him?” 21Others were saying, “These are not the sayings of one demon-possessed. A demon cannot open the eyes of the blind, can he?”
      22At that time the Feast of the Dedication took place at Jerusalem; 23it was winter, and Jesus was walking in the temple in the portico of Solomon. 24The Jews then gathered around Him, and were saying to Him, “How long will You keep us in suspense? If You are the Christ, tell us plainly.” 25Jesus answered them, “I told you, and you do not believe; the works that I do in My Father’s name, these testify of Me. 26“But you do not believe because you are not of My sheep. 27“My sheep hear My voice, and I know them, and they follow Me; 28and I give eternal life to them, and they will never perish; and no one will snatch them out of My hand. 29“My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of the Father’s hand. 30“I and the Father are one.”

For more info on this subject consider famous passage from C.S. Lewis’s book [Mere Christianity] (goodreads.com) (Book 2, Chapter 3: “The Shocking Alternative”). Lewis argues that Jesus cannot just be viewed as a great moral teacher, stating: “He would either be a lunatic — on a level with the man who says he is a poached egg — or else he would be the Devil of Hell.”
