John 4:46-50

So Jesus came again to Cana of Galilee where He had made the water wine. And there was a certain nobleman whose son was sick at Capernaum. When he heard that Jesus had come out of Judea into Galilee, he went to Him and implored Him to come down and heal his son, for he was at the point of death. Then Jesus said to him, “Unless you people see signs and wonders, you will by no means believe.” The nobleman said to Him, “Sir, come down before my child dies!” Jesus said to him, “Go your way; your son lives.” So the man believed the word that Jesus spoke to him, and he went his way.
