So, when [Peter] had considered this, he came to the house of Mary, the mother of John whose surname was Mark, where many were gathered together praying.
Acts 1:12-17 Being called by one’s name is a sign of inclusion, a sign that we are “known.” But when Luke, the writer of Acts, mentions a significant woman by name, he has to explain who she was because she was not well known: “Mary, the mother of John whose surname was Mark.” Most people would have been familiar with Mark, the cousin of Barnabas and missionary assistant to Barnabas and Paul. But very few knew Mark’s mother’s name.
Mary was not a leader that we know of. But she used what she had to serve the Jerusalem church. She apparently had a large house—vestibule, courtyard, and possibly two stories of living area—and a servant. Her house could be the one referred to as a meeting place in Acts 1:12-17; it was definitely a meeting place in Acts 12:12-17. It was the place where the church gathered to pray for Peter when he was imprisoned in Jerusalem.
You may not have a large house and servants, but everybody has something to use—including the abilities and spiritual gift(s) God has given you. Ask God to show you how to use for Him what you have from Him.
The highest honor in the church is not government but service.
