When he heard that Jesus was come out of Judaea into Galilee, he went unto him, and besought him that he would come down, and heal his son: for he was at the point of death.
Then said Jesus unto him, Except ye see signs and wonders, ye will not believe.
The nobleman saith unto him, Sir, come down ere my child die.
- John 4:47-49 KJV
*I also always think of a Latin phrase a friend of mine came up with which I used to tell the Jews for Jesus when they ambushed me at every street corner back when I worked downtown in the early 00s: "Nihil curo de ista tua stulta superstitione" (I'm not interested in your dopey religious cult).
