Then Jesus said:
“If anyone loves me, he will keep my word. My Father will love him and we will come to him and make our home with him. The one who does not love me will not keep my word. The word that you hear is not mine but is from the Father who sent Me.” — John 14:23-24
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.
