The book of Philemon is a letter written by Paul in thanksgiving primarily to the man Philemon, but also to those in the church that meets in Philemon's home. Philemon's name means "affectionate" and Paul describes Philemon this way throughout the letter, referring repeatedly to Phlemon's love for Christ and the saints and the great joy and encouragement he provides in refreshing the hearts of the saints. Paul encourages Philemon also in offering thanks and prayer for his effectiveness in sharing his faith. Paul also tells Philemon that he also has received great joy and comfort in his imprisonment when hearing about his love and the way the saints have been refreshed by him. Paul urges Philemon to receive his "son", Omnesimus, who is a convert under Paul's teaching, and he affectionately refers to him as sending "my very heart" to serve as a useful partner in the gospel. Finally, he encourages Philemon by expressing his confidence in his obedience, "knowing that you will do even more than I ask".
