John 20:30–31: "Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name."
John 21:25: "Jesus did also many other things, which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written."
