“Now Jesus did many other signs in the presence of the disciples, which are not written in this book; but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.” John 20:30-31
John’s Gospel account is my favorite Gospel. This was one of the first books of the bible I studied after becoming a Christian. I have often wondered, “What were all the other signs Jesus did that John did not record?” We don't know for sure, although the synoptic Gospels give us a few more miracles that John doesn't record. But one thing John does is he tells us why he includes what he does in his gospel account. That you may believe! John wrote everything he did with one point in mind– that you may understand who Jesus is and believe.
