Peter’s Night Vision
Then Peter dreamed that Jesus came to the rescue and, stretching forth his hand, took hold and lifted him up, saying: “O, you of little faith, wherefore did you doubt?”
In connection with the latter part of his dream Peter arose from the seat whereon he slept and actually stepped overboard and into the water. And he awakened from his dream as Andrew, James, and John reached down and pulled him out of the sea.
To Peter this experience was always real. He sincerely believed that Jesus came to them that night. He only partially convinced John Mark, which explains why Mark left a portion of the story out of his narrative. Luke, the physician, who made careful search into these matters, concluded that the episode was a vision of Peter's and therefore refused to give place to this story in the preparation of his narrative. ~ The Urantia Book, 152:4.2
