text: As a background to his specific plea for Onesimus, Paul clarifies his intentions and circumstances. Although he has the boldness to command Philemon to do what would be right in the circumstances, he prefers to base his appeal on his knowledge of Philemon's love and generosity. He also describes the affection he has for Onesimus and the transformation that has taken place with Onesimus's conversion to the Christian faith. Where Onesimus was "useless", now he is "useful" – a wordplay, as Onesimus means "useful". Paul indicates that he would have been glad to keep Onesimus with him, but recognised that it was right to send him back. Paul's specific request is for Philemon to welcome Onesimus as he would welcome Paul, namely as a Christian brother. He offers to pay for any debt created by Onesimus' departure and expresses his desire that Philemon might refresh his heart in Christ.
  Conclusion and greetings (21–25)
  In the final section of the letter, Paul describes his confidence that Philemon would do even more than he had requested, perhaps indicating his desire for Onesimus to return to work alongside him. He also mentions his wish to visit and asks Philemon to prepare a guest room. Paul sends greetings from five of his co-workers and concludes the letter with a benediction.
