John Mark, also known as "Mark," was one of the men who traveled with Paul on his missionary journeys. He is most likely the author of the Gospel of Mark.
* John Mark accompanied his cousin Barnabas and Paul on their first missionary journey.
* When Peter was put in prison in Jerusalem, the believers there were praying for him at John Mark's mother's house.
* Mark was not an apostle, but was taught by both Paul and Peter and worked together with them in ministry.
