The answer is: Cousin

Colossians 4:10 - Some older versions have translated as sister's son (or nephew) but the Greek word here 'anepseeos' is the word for cousin and is translated as such in modern translations.

The link between John Mark and Barnabas adds a layer of richness to our understanding of the early church. Barnabas himself was an ardent supporter of Paul, bringing him into the fold as a trusted companion. You can imagine the dynamics when John Mark, who is indeed Barnabas' cousin, joins their missionary efforts. This familial connection might explain the close bond and resilience they showed together, especially during those tumultuous journeys to spread the message.

It's also fascinating to note how John Mark's role evolved over time. Initially, he accompanied Barnabas and Paul on their first journey. However, a rift formed when John Mark left the mission early, leading to contention between Barnabas and Paul. This split is intriguing because it highlights the human side of these early leaders. Even the mightiest figures faced struggles within their relationships! Ultimately, John Mark found his footing again, with later references in the New Testament indicating he became an important figure in the church, eventually credited as the author of the Gospel of Mark.

Beyond this familial and youthful drama, consider how John Mark symbolizes a broader theme in Scripture: the idea of redemption and second chances. His early departure could have been viewed negatively, but he is welcomed back later. Has anyone considered that it encourages us to give grace to those who stumble, believing they can rise again? That's the very essence of growth in community!
