Then Jesus said:
“If anyone is ashamed of me and my words, the Son of Man will be ashamed of him when He comes in His glory and in the glory of the Father and of the holy angels” — Luke 9:26

And C.S. Lewis said:
“A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic — on the level with the man who says he is a poached egg — or else he would be the Devil of Hell.
“You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse.” – C.S. Lewis, Mere Christianity.
