As Paul winds down his exposition of the gospel in this monumental letter to the Romans, he concludes by commending individuals who were laboring in kingdom work. Two categories of kingdom workers stand out: coworkers and hard workers. Paul highlights the labor of Prisca and Aquila who were now in Rome and who had joined with him in ministry in Corinth and Ephesus. He also calls attention to 4 women who worked really hard in the Lord. This list reminds us that God uses all kinds of men and women, ordained and non-ordained, to advance His kingdom.
