This little letter is a book of one chapter is primarily address to Philemon whose house the church was meeting in as outlines in the first verse. This first verse as well as verse nine and thirteen tells us that Paul was an old man in prison when he wrote the letter, but Paul was hoping to visit soon as mentioned in verse twenty two.
Paul as often the case when opening his letters greatly encourages them of their Godly love for one another and their faith in the Lord, which brought great joy to Paul himself (Philemon 4 to 7)
The main of the chapter (Philemon 8 to 21) concerns the relationship between Philemon and Onesimus. Onesimus had been a slave to Philemon, was now with Paul. Paul had led Onesimus to the Lord while he was in prison, and with compassion was suggesting he return to Philemon requesting Philemon would accept him back as a brother in Christ.
The letter reads - 1 Paul, a prisoner of Christ Jesus, and Timothy our brother,
To Philemon our dear friend and fellow worker— 2 also to Apphia our sister and Archippus our fellow soldier—and to the church that meets in your home:
3 Grace and peace to you[a] from God our Father and the Lord Jesus Christ.
4 I always thank my God as I remember you in my prayers,5 because I hear about your love for all his holy people and your faith in the Lord Jesus. 6 I pray that your partnership with us in the faith may be effective in deepening your understanding of every good thing we share for the sake of Christ. 7 Your love has given me great joy and encouragement, because you, brother, have refreshed the hearts of the Lord’s people.
8 Therefore, although in Christ I could be bold and order you to do what you ought to do, 9 yet I prefer to appeal to you on the basis of love. It is as none other than Paul—an old man and now also a prisoner of Christ Jesus— 10 that I appeal to you for my son Onesimus] who became my son while I was in chains. 11 Formerly he was useless to you, but now he has become useful both to you and to me.
12 I am sending him—who is my very heart—back to you. 13 I would have liked to keep him with me so that he could take your place in helping me while I am in chains for the gospel.14 But I did not want to do anything without your consent, so that any favour you do would not seem forced but would be voluntary. 15 Perhaps the reason he was separated from you for a little while was that you might have him back forever—16 no longer as a slave, but better than a slave, as a dear brother. He is very dear to me but even dearer to you, both as a fellow man and as a brother in the Lord.
17 So if you consider me a partner, welcome him as you would welcome me. 18 If he has done you any wrong or owes you anything, charge it to me. 19 I, Paul, am writing this with my own hand. I will pay it back—not to mention that you owe me your very self. 20 I do wish, brother, that I may have some benefit from you in the Lord; refresh my heart in Christ.21 Confident of your obedience, I write to you, knowing that you will do even more than I ask.
22 And one thing more: Prepare a guest room for me, because I hope to be restored to you in answer to your prayers.
23 Epaphras, my fellow prisoner in Christ Jesus, sends you greetings. 24 And so do Mark, Aristarchus, Demas and Luke, my fellow workers.
25 The grace of the Lord Jesus Christ be with your spirit.
