Then Jesus said:
“What comes out of a person, that defiles him. For from within, out of people’s hearts come evil thoughts, sexual immoralities, thefts, murders, adulteries, greed, evil actions, deceit, lewdness, stinginess, blasphemy, pride and foolishness. All these evil things come from within and defile a person.” — Mark 7:20-23

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.
