Then Jesus said:
“I am the resurrection and the life. The one who believes in me, even if he dies, will live. Everyone who lives and believes in me will never die, ever.” — John 11:25-26

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.
