Then Jesus said:
“If anyone loves Me, he will keep My word. My Father will love him and We will make come to him and make Our home with him … The word that you hear is not from Me, but is from the Father who sent Me.” — John 14:23

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.
